Hi I'm interested in a feature, and I want to know if VDDK has such a feature. I want to register my own callback which will be called before calling th read() and write() funcntions to the vmdk. Or maybe create a new vmdk for a VM and register my own read and write which will perform some operations and then call the regular read and write functions. Thanx Wagde

While running this sample program on Windows 2003, I'm getting error: SSLLoadSharedLibrary: Failed to load library libeay32.dll:126 - Failed to resolve dbghelp.dll symbols. No backtrace.---- Win32 object usage: GDI 5, USER 0 CoreDump: Writing minidump to C:\Documents and Settings\Administrator\Application Data\VMware\vixDiskLibSample-5756.dmp Any ideas why and how to resolve this?

May i know using vmware virtual disk development kit can create a virtual disk and share like iscsi ? Or can do such like iSCSI Target ? Client's pc can connect with the virtual disk and read it. Thank You !

The file name is Wide Character, then I call the Win32 API WideCharToMultiByte to change it MultiByte. uint32 openFlags = VIXDISKLIB_FLAG_OPEN_READ_ONLY; char fn[MAX_PATH]=; WideCharToMultiByte(CP_OEMCP,0,fullPathName.c_str(),fullPathName.size(),fn,MAX_PATH,NULL,NULL); VixDiskLib_Open(connection, path, flags, &_handle); after execute this , it's seem the SDK can't handle this kind of encode. But anyway, the english file name of VMDK file can be opened successfully. But if the chinese file name, it will failed. This the error message box popup screen-shot. Does anyone could give me idea ? How to covert the wide character to multi-byte character to conform the VixDiskLib_Open function requier ?

Apologies if this is the wrong community for this question, but it seemed the closest to what I want. My company is working on a tool that, among other things, creates VMDKs for use with ESX. We're working on a way to automatically upload the created VMDKs to ESX servers. One problem we're running in to is that best practices for VMFS suggest VMDKs should be pre-allocated and that using tools like scp to copy VMDKs over to ESX is a bad idea due to the fact that scp will keep appending to the file until it's transferred, as opposed to preallocating it first. Users of SCP are told to use Veem's tool or use vmfsctl to copy the VMDK into the repository, but neither of those options are acceptable to us for various reasons. My question, then, is this: From C code running on the service console, what is the proper way to create a VMDK and subsequently populate it with data such that VMFS is properly utilized and an excess of SCSI reservations are not generated? Is there a VMFS system call for this, or a function exported from a library? How does vmfsctl accomplish it? Thanks in advance for any help. Adam

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 : 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.

Hi all, Can any one know about how to get the virtual device node list. in Virtual infrastructure client while creating rdm/vmdk the create wizard will ask to select any one virtual device node. i need to do this programatically,is there is any property in esxsever to get these virtual device list, i attached screen shot Sample.jpg just have a look.if any one having sample code please paste it. Thanks karthik.
