How do I find the VixVolumeInfo.inGuestMountPoints for volumes that are mounted on a clean NTSF folder

red0mark — Fri, 20 Nov 2009 15:46:31 GMT

I have a vm guest with 2 disks… the boot disk is mounted at C: but the second disk it mounted on a founder in the C: file system.

E.g.
C:\drivef is a mount point for my second disk.

The VixVolumeInfo for the inGuestMountPoints is null so is there another way I can determine that the mound point is C:\drivef

Thanks,
-Ron

Limit on the number of mounted disks

giladb — Mon, 09 Nov 2009 21:42:37 GMT

Is there a limit on the number of simultaneous virtual disk that can be mounted with vmware-mount ?
What about mounting VDDK ?

Assuming I am mounting the disks on a Linux machine, is there a limit from the Linux side ?

Failed to open vmdk

MissionaryLiao — Mon, 02 Nov 2009 08:19:23 GMT

Hi all,

Here is some of my environment info:
- VMWare ESXi 4.0.0, 164009
- VMWare vCenter Server 4.0.0, 162856
- GuestOS: Win2k3 Server SP2

I use VixDiskLib_Open to open a vmdk, however, I got the error code: 0x36b9(14009): VIX_E_HOST_NETWORK_CONN_REFUSED.
I was confused by this error code because there is no error returned when I called VixDiskLib_Init and VixDiskLib_Connect.

Also there is no relative document on this error code, only short description: The server refused connection.

Can anyone here give me some hint for further investigation ?? Thanks.

VDDK Logging

giladb — Thu, 29 Oct 2009 19:04:03 GMT

When calling both VixDiskLib_InitEx and VixMntapi_Init my code provides all three logging functions.
Yet, there are still messages written to standard output, such as

[2009-10-29 11:51:47.209 B763BB30 info 'App'] Current working directory: /mnt/disk2/home/devel/trunk

[2009-10-29 11:26:10.032 B75A3B30 trivia 'SOAP'] Received soap response from [TCP:10.10.42.200:443]: GetConfig

How can these messages be prevented, or redirected to my own logging functions ?

VixDiskLib Opening delta disks (snapshots

tos2k — Wed, 28 Oct 2009 12:26:08 GMT

Hi!

Is it possible to open delta disks with VixDiskLib? Currently connect fails for me:

The VM has that snapshot, is powered-off and the connect works fine for base disks... Any ideas?

VixDiskLib_Open on RDM (Raw Device Mapping) always returns VIX_E_FILE_ALREADY_LOCKED

red0mark — Mon, 26 Oct 2009 15:09:57 GMT

All,

Does VDDK 1.1 support RDM(s)? We have a Window XP vm guest with a RDM but the call to VixDiskLib_Open always returns VIX_E_FILE_ALREADY_LOCKED. We are opening the disk in VIXDISKLIB_FLAG_OPEN_READ_ONLY mode.

Thanks,

can't mount remote vmdk

kinc — Wed, 21 Oct 2009 15:37:37 GMT

Hi,

I'd like to use vmware-mount to remotely mount a vmdk on our ESX 4 server,
but can't seem to be able to:

bash-3.2# vmware-mount -h esx -u root -F /root/infoblox 'Storage1Ubuntu/Ubuntu.vmdk' /tmp/vmdk

Any help is appreciated.

Multiple threads created by VDDK

giladb — Tue, 20 Oct 2009 17:27:36 GMT

I have a single threaded Linux application that uses VDDK.
While trying to connect to a virtual disk, ps shows that I have two additional threads (or processes), probably created by VDDK.
What are these additional threads ?
Is this behavior documented ?

VDDK Implementation Difficulty Question

RColbert — Mon, 12 Oct 2009 18:46:31 GMT

One of the new features of Windows 7 and Windows 2008 R2 is the ability to create/mount/manage VHDs from the host's LDM.

My question is how difficult would something like this be to implement using VDDK 1.1?

Any ideas on difficulty would be appreciated.

Can`t find best way of remote management

DinoPozzo — Mon, 14 Sep 2009 17:28:35 GMT

Hello!

I know that posting here my question is not really correct, but I need immediate answer very much, so please help me!

We`re upgrading
our few years old system to new configuration. Here is it:

-Dual Xeon-2.8 GHz CPU, 4Gb RAM, 1TB HDD

-Xeon 7000 Sequence, 8GB RAM, 4 TB HDD

-Intel Xeon DP 3.8F, 4 GB RAM, 2TB HDD

I`m running
MS Windows Server 2003 R2 on old stuff. I want to install Windows Server Core
R2, and manage it remotely, either iSCSI,
while on other 2 – Widows Server 2008 R2.
I`d like to install Server Core R2 to Xeon-2.8, to run Active Directory Domain
Service and Hyper-V on it.

Also I`m
thinking to purchase Discs Array HP StorageWorks MSA60. My old shared storage was managed by such iSCSI solution
as SvSAN, but it`s no good for me now.

What would
you adjust me, please?

Thank you!

VixDiskLib_Clone() Error

Alberto Gonzalez — Mon, 07 Sep 2009 10:05:28 GMT

Hi,

I am working in a project using VDDK API. I have been able to Connect, Open, Read and Write to VM virtual disks using VixDiskLib. But I have a problem using VixDiskLib_Clone() function to copy a vdisk. I have defined this function:

public static bool Clone(vixDiskSourceVixDisk, string SourceDiskPath, vixDisk TargetVixDisk, string TargetDiskPath, VixDiskLibProgressFunc ProgressFunc)
{

VixDiskLibCreateParams CreateParams = new VixDiskLibCreateParams();

CreateParams.adapterType = VixDiskLibAdapterType.VIXDISKLIB_ADAPTER_SCSI_LSILOGIC;
CreateParams.capacity = 20 * 2048;
CreateParams.diskType = VixDiskLibDiskType.VIXDISKLIB_DISK_MONOLITHIC_SPARSE;
CreateParams.hwVersion = vixDiskLib.VIXDISKLIB_HWVERSION_WORKSTATION_6;

IntPtr clientData = (IntPtr) null;
ulong ulStatus;

ulStatus = vixDiskLib.Clone(TargetVixDisk.VixConnHandle, TargetDiskPath, SourceVixDisk.VixConnHandle, SourceDiskPath, out CreateParams, ProgressFunc, clientData, true);

if (ulStatus != 0)
{
string msg = vixDisk.GetError(ulStatus);
return false;
}
return true;
}

If I define Target Server as blank "" to copy to local and call Clone() I get error: "invalid parameter was supplied"

TargetVmdkPath = @"C:\Users\Alberto\Desktop\vddk\test.vmdk";
TargetServer = "";
TargetVmxPath = "";
TargetDatacenter = "";
TargetDatastore = "";
TargetUser = "";
TargetPass= "";
TargetPort = 0;

If I define Target as ESX I can Connect,Open, Read.. disks in that ESX with Connect(), Open(), Read(). But when I call Clone() I get error: "Cannot connect to host" (17179887184) and I get this log in ESX hostd.log:

Technology Exchange Developer Day - Demo on VDDK, a part of vStorage APIs

navadavuluri — Wed, 19 Aug 2009 01:58:03 GMT

Hello,

We are happy to announce about our hands-on demo at Technology Exchange Developer Day 2009, Demo on VDDK(Virtual Disk Development Kit), a part of vStorage APIs
Presenter: Sudarsan Piduri

Demo ID: DS-07

Time: 5:45 - 6:45 PM

Abstract:

VixDiskLib and VixMntapi libraries can be used to manipulate virtual disks in both hosted and virtual infrastructure environments.
These libraries can be used to enable on-line backups of running VMs from outside the VM. This demo will illustrate some
additional use cases, like the use of these libraries to perform disk and file level tasks such as checking for presence of a file
on a powered off vm. The demo is implemented using standard C.

Windows volume mount warning for BCD & boot.ini?

red0mark — Fri, 31 Jul 2009 15:49:04 GMT

All,

What is this error and how does one correct it? I've run chkdsk & fixmbr on the virtual machine and my local machine but on luck so far. I see
this only on one on my vm systems. The VDDK 1.1 host system is XP Pro SP3 and the vm guest is also XP Pro SP3 on an ESXi server.

Thanks,

Creation of VMFS file system taking longer time on ESX server 3.5 Update 3

satyakada — Thu, 23 Jul 2009 06:11:01 GMT

Hi All,

I need help on to identify the issue while creating the datastore on ESX server 3.5 with Update 3. The issue is it is taking very long time to create VMFS file system. I am using third party vendor SAN, created VDisk and mapped the VDisk using FC to the esx server. I am using this LUN and creating datastore.It is taking longer time to create datastore and sometimes it is failing also. What might be the issue? Is the LUN and VPort are not good state, if so how to identify the state of the path?

Thanks,

--Satya.

Prepare to shrink. it's not working in offline mode

Kim76 — Tue, 21 Jul 2009 11:20:29 GMT

Hi all

I'm using these commands to shrink my 4 GB dynamic vmdk disk:

vmware-vdiskmanager -d "C:\Virtual Machines\w2kpro\w2kpro.vmdk"
vmware-mount J: "C:\Virtual Machines\w2kpro\w2kpro.vmdk" /v:1
vmware-vdiskmanager -p J:
vmware-mount J: /d
vmware-vdiskmanager -k "C:\Virtual Machines\w2kpro\w2kpro.vmdk"

and the size for reduces with about 200 MB every time I run the batch

If I start the gust OS and Prepare to shrink through VMware tool manually in the control panel and just power off guest OS with out the shrink option and run
vmware-vdiskmanager -k "C:\Virtual Machines\w2kpro\w2kpro.vmdk" then the vmdk file resize from 4 GB to 1,6 GB, in offline mode.
it must be something with the mapping of vmdk file.

Is there anyone ho know what the problem is?

VixDiskLib_Clone() just for conversion?

nicok — Fri, 10 Jul 2009 15:45:10 GMT

Hi,

I need some clarification about the VixDisklib_Clone() function.

Is the function only intended to move a vmdk from a local host to a ESX?

Could I use that function also to simply create a copy of my vmdk on the ESX?

Thanks in advance.

cannot connect to host

ayrus — Thu, 18 Jun 2009 07:45:27 GMT

I ve been working with VDDK programming API for the past couple of weeks. I encounter the following error when i am trying to connect the the managed disk on the esx server from another VM running on the same esx.

I issued the following command in windows xp: vixDiskLibSample.exe -info -host <host ip> -user root -password "1234" "Storage1/test/test.vmdk"

It worked fine with some warnings. like "host certificate chain is not complete" failed to read registry value .
"certificate verification is disabled so connection will proceed despite the error". And it showed the disk info .

I tried the same command in my ubuntu linux. (which is actually a VM in the same esx)

./vix-dislib-sample -info -host <host ip> -user root -password "1234" "Storage1/test/test.vmdk"

Getting the following error.

INFO: VixDiskLibVim: TicketLogin

(process:6770): WARNING **: VixDiskLibVim: Login failure - VixError = 0.

Error: ~~vixDiskLibSample.cpp:388~~ 4650 Cannot connect to host

PLZ HELP ME TO GET OUT OF THIS.

Thanx in advance.

HotAdd transfer mode using VDDK APis fails

dhd9 — Sat, 23 May 2009 05:50:48 GMT

Hi,
I'm using VDDK's Flexible transfer mode APIs VDIskLib_InitEx and VixDIskLIb_ConnectEx etc. for HotAdd transfer mode inside VM. But If I see logs, it fails and fall backs to nbd transfer mode.
I'm not sure what is issue here.
Is there any special configuration required for HotAdd transfer mode inside VM ?

Thanks in advance

troubles with vmware-mount "file not found" ??

soonblue — Fri, 22 May 2009 17:56:18 GMT

I work for the University of Delaware as a systems programmer and I'm looking to set up file-level backups using vmware-mount and our own networker software. I'm very close to being able to mount virtual disks remotely, but keep running into the following problem. A command-line run of vmware-mount and fuseMount.log are below:

Cannot mount vmdk file

writetonikhil — Wed, 13 May 2009 10:16:34 GMT

Hi all,

I am trying to mount a vmdk file on Windows XP. If I do it manually using the vmware-mount utility, I can mount it and access the VM without any issues. But if you fire the same command through a perl script(using Perl's 'system' command), I can mount the vmdk. The error I get in the vmware-mount logs is:

I couldnt find anything related to the error no. 30009. The strange thing about this issue is, the same vmdk file was getting mounted few hours back and I haven't changed anything on the VMDK file. Attached is the full vmware-mount log file.

Child vdmk files can be opened only with ESX credentials ?

flatino — Wed, 29 Apr 2009 16:14:07 GMT

Hello,

I have a Linux program which calls VDDK API to connect and read VMDK files.

I have a problem working with CHILD / snapshots files like <image-name>-000001.vmkd.

If my linux program (invoking VDDK) runs locally on the ESX server without authentication (no host/pwd/user provided) -> I got error 16006 VIX_E_DISK_NEEDSREPAIR

If my linux program (invoking VDDK) runs on another machine and I remotely connect to ESX server (provising credentials) -> it works.

With all parent VMDK files I have no problems: my linux program runs locally and can see all VMDK files without authentication.

I have this problem only with CHILD VMDK files

Does this mean that to open and read child VMDK files, we must use VDDK with ESX authentication parameters (user/pwd/host parameters) ?

Many thanks in advance,

Francesco

Suppress warning popup for missing library

flatino — Tue, 21 Apr 2009 18:00:14 GMT

Hello,

if I run the sample code vixDiskLibSample.cpp (on both Windows and Linux systems) and a DLL / SO is missing, I have a popup in Windows and a prompting message on Linux which is stopping

the application to continue and it requires the manual user intervention: is there a way to suppress this warning ?

As example:

Rename libeay32.dll so that it is not found when running VixDiskLib_Init method

you will get a popup with the error message and you have to click "OK" button to continue

(on Linux you have a "Press ENTER to continue".....)

I would prevent any popup/prompting message to appear: is there a way ?

I implemented my own logger method as follows

-----------------------

void logger(const char *fmt)
+ { <MY_LOGGER_CODE> }+

VixDiskLib_Init(VIXDISKLIB_VERSION_MAJOR, VIXDISKLIB_VERSION_MINOR, &logger,&logger,&logger, NULL);

-----------------------

and it is correctly invoked but still the warning popup appears.....Is there a way to remove it ?

Thanks,

Francesco

Remote VMDK locked after crash - how do I clear the locked state

unideskjohn — Thu, 12 Mar 2009 17:20:54 GMT

Hello,

I am implementing remote VMDK access via the VVDDK. I am encountering an intermittent problem which happens when the code under development crashes and does not exit cleanly. One the subsequent run I get the following printout from the library:

XXX::mount, open file storage1 M4-MM-BOOT/M4-MM-BOOT.vmdk returned error 5, This function cannot be performed because the handle is executing another function

From this point on the VMDK cannot be opened even if I reboot the machine machine the open request. That is why I am assuming there is some locked state being set and never being cleared. The remote VMX is not executing, meaning the machine is in the powerted off state when this test is run. In fact the machine has never been powered up.

Is there a way to clear this locked state programatically? Is there a way to clear this locked state manually?

Thank you in advance,

John

Unable to mount VM through VC. Error: Unable to get VIM ticket.

GautamB — Fri, 16 Jan 2009 06:57:07 GMT

Hi all,
I have ESX 3.5 with VC 2.5. I want to mount vmdk files of offline VM using VDDK utility. When i mount vmdk file through ESX it gets mounted successfully, but when try to I mount vmdk file of same VM through VC, it gives error as Unable to get VIM Ticket.
I also referred VDDK logs and it gave error as.
"Warning: VixDiskLibVim: TicketFindVMCb failure - VixError = 4000." as error.
"Unable to get VIM Ticket. Error code = 0xfa0"

Following are commands i use:
In case of ESX: vmware-mount.exe H: "[storage1 (1)] MyVM/MyVM.vmdk" /i:ha-datacenter/vm/MyVM /h:ESX3.0.1Host /u:root /s:password
this command works fine.

In case of VC: vmware-mount.exe H:"[storage1 (1)] MyVM/MyVM.vmdk" /i:sandeep/vm/MyVM /h:VCServer /u:VC IP /s:password
this gives error as "Unable to get VIM ticket"

Note that this VM have no snapshot, so i think I am not mounting wrong vmdk file.
above two commands works perfect for other VM in the same inventory.
I get VMDK path in VM's Settings dialog for the Hard Disk device in VI client. Inventory path is also correct in above command, as it is working

Please tell me what I am doing wrong? What is correct path to mount VM through VC?

Creating virtual disk using VDDK

vixDiskLib_Read_Ptr declaration error in vixDiskLibSample.cpp

JaekSmith — Sun, 07 Dec 2008 03:04:54 GMT

In the sample file vixDiskLibSample.cpp distributed with the development kit, there's an error with the VixDiskLib_Read_Ptr function numSects parameter:

Here's how it's declared in the CPP file.

static VixError
(*VixDiskLib_Read_Ptr)(VixDiskLibHandle diskHandle,
VixDiskLibSectorType secOffset,
uint32 numSects,
uint8 *readBuffer);

This causes the function to return an error of 3 (parameter error)

(Note to misc readers: This declaration is only used if you use dynamic loading (define DYNAMIC_LOADING) - otherwise you won't have an issue since the actual spec will be used).

Modifying the declaration based on the declaration in vixDiskLib.h to:

static VixError
(*VixDiskLib_Read_Ptr)(VixDiskLibHandle diskHandle,
VixDiskLibSectorType secOffset,
VixDiskLibSectorType numSects,
uint8 *readBuffer);

Fixes it and the function call then succeeds.

VM mounting using VDDK API

Ashwin89 — Fri, 05 Dec 2008 22:14:15 GMT

Hello.

I am having couple of VM's that are present on the ESX server.

I am using vcbmounter command line utility to mount them and after that backed it up.

Is there are any API's available which will do the mouting of VM (instead of using vcbmounter) ?

I want to avoid the use of vcbmounter.

trouble accessing mounted drives from windows service

jx — Wed, 26 Nov 2008 21:35:07 GMT

Hello All,

I am having some trouble with accessing a file vmware-mount'ed drive from a windows service. I mounted the vmdk on to V: drive. I am trying to open the file V:\test.txt using CreateFile() API. But it always returns win32 error 3 (ERROR_PATH_NOT_FOUND). This happens only when I run my application as a windows service. If I run it as normal process, it works fine. It looks like it is expecting the path in \\?\Volume{GUID}\ format. So I tried to retrieve the volume name of the mounted drive by calling

TCHAR szVolNameMAX_PATH;

BOOL ret = GetVolumeNameForVolumeMountPoint(_T("V:
"), szVolName, MAX_PATH);

DWORD err = GetLastError();

But I always get error 87(ERROR_INVALID_PARAMETER)

I also tried changing the logon user settings of the service so that it runs as the same user who mounted the drive - not still same errors...

Have you ever faced this problem ? What the "proper" way of accessing vmware mounted drive from a serice process??

Thanks

vmware-mount Failed to analyze snapshot chain

veggiefrog — Thu, 18 Sep 2008 19:57:09 GMT

I have been having a problem trying to mount a vmdk file with vmware-mount under Ubuntu Linux. vmware-mount keeps giving me the error: "Failed to analyze snapshot chain". The virtual machine I am mounting the disk from has 2 disks attached, and if I remove the second disk the vmware-mount command works. It seems a problem when more than 1 disk is attached to a VM. Has anybody else seen this problem, or have a resolution?

Here's more information:

all vmdk's are stored on NFS mounts
datastore is mounted under Ubuntu Linux VM
VDDK 1.0.1 build 99191 is installed
VM is powered off

Thanks for any help,
Andrew.

Back up with Windows VSS.

drorms — Mon, 08 Sep 2008 13:05:16 GMT

Let's say, I have 3 physical LUNs connected to ESX server, one VMFS datastore was created and virtual disks were assigned to a Windows 2003(2008) guest OS.
I would like to back up the file systems in the Windows guest using a third party backup software supporting VSS(Volume Shadow copy Service) and our VSS provider to create a storage array snapshot.
I have several questions:

On the VSS provider, we would like to recognize our physical LUNs and create a storage array snapshot. However, the virtual disks are recognized with vmware specific personality("VMware Virtual Disk") - is it possible to get the information about the physical LUNs?
During a VSS snapshot, the Windows OS (guest in vmware) synchronizes the Writers and flushes file systems, the data is written to the ESX virtualization layer and might be cached in the VMFS, is it possible to flush the VMFS from the guest OS?

vmware-mount : how to mount ntfs partition with r&w mode?

rajesh_battala — Wed, 03 Sep 2008 10:28:36 GMT

hi all..

i have installed vmware disklib on opensuse11.its working fine with linux partitions.

when i mount the ntfs partition, it mounts in read only mode, i have installed ntfs-3g driver.

even after that also the ntfs partition is mounting in read mode only.

i want to push some files in to the mount point.

can any one tell me how to make the vmware-mount to use the ntfs-3g driver for mounting ntfs partition in both read&write mode.

or can we change the read only mount point to remount forcely with read and write mode.

thanks

Problems automating tasks with vmware-mount

rajesh_battala — Sun, 24 Aug 2008 09:23:15 GMT

hi all.

i have written a bash script which finds the no of partition and mounts (remotely on my linux box) the vmdk of the esx server vm.

when i run the script manually in the terminal its working properly but

i have written a jython script to automate this task, to execute this script from the jython script ( using cmd.exec()). when the script got executed its not terminating the vmware-mount process a even after the process got over.

in my script first i use

1. vmware-mount -p -v inv_path -u user -h ip -F pass_filename <image_disk location> > /tmp/partitions

filter (/tmp/partions) so that it contains valid mountable partitions.

2. reading each file and mounting the disk partion on the linux machine.

when i run this from the bash script manually it works fine..

but when i invoke the script from the jython script,

when it executs cmd 1 ( vmware-mount -p -v inv_path -u user -h ip -F pass_filename <image_disk location> > /tmp/partitions ) after its sending the output to the file still the process exists its not getting killed.

its not letting me to use next command to mount the disk, as that file is already using by the above process.

and the cmd.exec is a synchronous call only. but its not waiting for it to complete.

but when i execute other files using the same jython script. it works fine.

i want to mount the disk remotely on a linux box and want to patch the vm.

can any one please solve this issues!!

can we mount the vm locally on the esxserver itself with vcbmounter to patch the VM in offline mode (if yes, please post the commands , it ll be very helpful )

thanks alot.

question on vm mount when used on different user sessions

ericschu — Wed, 30 Jul 2008 20:41:08 GMT

While using vmware-mount.exe, we see that after we mount/unmount a virtual disk in one Windows session (e.g., session 0), we are unable to mount and access files on any virtual disk in any other session.

It looks like the first invocation of vmware-mount.exe starts another instance of vmware-mount.exe as a user-mode driver process which stays running. Mounts work in whatever Windows session this second, long-lived, process runs. Other sessions then do not work.

We do not need a disk mounted in one Windows session to be accessible outside that session, but we do need to be able to mount different disks in different sessions. Is there a way to do this?

How do I know the VMDK contains mixed partitions/volumes?

ashvitech — Thu, 12 Jun 2008 15:48:19 GMT

I am using VMware's VDDK APIs and mount utlitiy. By using /p option on windows, it displays the volumes.

vmware-mount "E:/VMs/WinVM.vmdk" /p

Volume 1: 4094 Mb
Volume 2: 7 Mb

Sometimes utlitiy displays file system info :
Volume 1: 456 Mb HPFS/NTFS

Is there any way to know specfic file system for volume (whether it is Windows or Linux)? So that in mixed partitions case I can mount serately using linux and windows host.

Thanks in Advance...

VMDK format specifications

RDM (What could be the problem)

hishivahere — Tue, 13 May 2008 07:06:08 GMT

Hi Mac,

For creating RDM we need to do the following:

Create the VirtualDeviceConfigSpec and set its properties.
Create VirtualMachineConfigSpec object and set the VirtualDeviceConfigSpec to the device change property of VirtualMachineConfigSpec object.
3. Call the ReconfigVM_Task.

If I follow the process 1 specified below getting the error “Incompatible device backing specified for device 0 “ as it is unable to create the vmdk file with the path specified in

backingInfo->fileName. If I specify backingInfo->fileName=”datastorename” then it is creating Virtual Disk with unknown size which is not RDM.

But if I follow the process 2 , first create vmdk file and then specify this file in backingInfo->fileName, its working fine.

But the problem is it works only in case of ESXServer not Virtual Center because for creating VirtualDisk_Task, it takes VirtualDiskManager as

Parameter which is not set in case of Virtual Center.

So we are unable to understand why it is failing to create the RDM in process 1.

I am also enclosing the link where the guy is able to create RDM using Process 1.

Link : http://communities.vmware.com/thread/38923;jsessionid=14172672B2B1D99EBB70617BD6066CE5?tstart=15

We came to know how to set the values for the following properties also

backingInfo->lunUuid

vdCfgSpec->device->unitNumber

vdCfgSpec->device->controllerKey

I also tried setting the below property in process 1 but no use

vdCfgSpec ->fileOperation = VirtualDeviceConfigSpecFileOperation::create;

vdCfgSpec ->fileOperationSpecified = true;

I am still working on this, but if you find any solution on process 1, please let me know.

Thanks & Regards

vdiskmanager - how to convert into a remote disk ?

continuum — Sun, 04 May 2008 21:09:04 GMT

In the past I used vdiskmanager for p2v by using the convert option: I created a disk type "fullDevice" and used the -r command to convert that disk into a regular one.

Now that vdiskmanager can handle remote disks - how do I do this now ?

In details:
I have "source.vmdk" which is a disk type "fullDevice". (in my case this would be a 1kb file stored in the ramdrive of my LiveCD)
I want to import this "vmdk" into ESX without storeing it on a local host first.

Is it possible to use somehow 'pipe' the output of vdiskmanager -r into a disk mounted with vmware-mount.exe

vmware-mount.exe Q: /i:"ha-datacenter/vm/name_of_VM" " local12gigs name_of_VM/xp-sp2.vmdk" /h:10.0.0.35 /u:root /s:password7 /v:1

can any one help me How to create a Vmdk/rdm using sdk call

karthimin — Wed, 30 Apr 2008 09:15:16 GMT

Hi all,

Here my task is to create vmdk or rdm.

Can any one help me how to create a vmdk or rdm using vmware sdk call.Here i am calling this method to create vmdk 'CreateVirtualDisk_Task ' is this the method to call or any other method available to create vmdk?

i am bit confused with parameters for this method CreateVirtualDisk_Task .here i am hot coding the parameters to create vmdk like this "m_pVimSvc->CreateVirtualDisk_Task(imor,"Dsc_0121 Hello/Hello.vmdk",nullptr,xx);" but it's failing to create the error message i got was "invalid parameter" afeter researching i came to know i need to fill "virtualdiskspec" can any know how to fill this spec?

Thanks in advance...
