Error input / output during Host Profile Apply

krfa261286 — Mon, 23 Nov 2009 10:13:11 GMT

Hi everybody,

I've installed 4 esx 4 servers and added they to the vCenter. I configure all options in one ESX server, and confiure new Host Profile with this ESX server for reference.

When I would apply this profile on another server, I receive everytime this error :

Apply host configuration
xxx.xxx.xxx.xx
Error during the
configuration of the
host: Input/output
error: Input/output
error
xxx\xxxxxx
xxx.xxx.xxx.xx

But I don't find any solution to resolve this issu.

Somebody can help me?

P.S : sorry for my English

PowerCLI & host name

DougBaer — Wed, 11 Nov 2009 15:29:09 GMT

I do not believe there is a cmdlet for this. You're talking about the NetworkSystem.


Connect-VIServer ESX_HOSTNAME
$HS = Get-View -VIObject (Get-VMHost ESX_HOSTNAME)
$NS = Get-View $HS.ConfigManager.NetworkSystem
$NS.DnsConfig

You'll probably need to create a HostDnsConfig object and pass it to UpdateDnsConfig.

If that isn't enough to nudge you in the right direction, this may be:

$dnsconfig = $NS.NetworkConfig.DnsConfig # copy the existing values

$dnsConfig.hostName = "MYHOSTNAME"
$dnsConfig.domainName = "MYLAB.LOCAL"
$dnsConfig.SearchDomain = ("MYDOMAIN.AZ.US","AZ.US")

$NS.UpdateDnsConfig($dnsConfig)

Good luck

Can a vm bootstrap trigger an action?

Park3r — Thu, 29 Oct 2009 10:05:49 GMT

Hi,

I was wondering whether it's possible to setup an even handler kind of thing which would trigger an action/function whenver a vm is bootstraping. Not loading the OS, but bootstraping- the stage before OS loads.

Time to time there are operations I need to perform which require to power down a vm, or all vms on a lun or on a host. It's difficult to schedule a down time, since the vms are used by multiple teams. If the even handler thing was possible, I could just setup a script which would perform the desired action as soon as the user reboots (from within the OS). The end user won't notice anything (except some delay until the vm comes back online) and I get my tasks done. E.g. I need to redo a LUN, but can't vmotion some vms since they have snapshots. The task is not critical/urgent, so I would give it few weeks. After that there is a big chance all (or most) vms were rebooted and migrated somewhere else.

Any ideas?

Automatically remove snaphots older than X days

a2alpha — Tue, 27 Oct 2009 13:52:52 GMT

No problem,

Just realised, right-click on the snapremdate.ps1 file select properties and then select unblock.

This should get rid of the request for running it.

Problem getting vSphere CLI 4.0 installed on Ubuntu 9.04?

lamw — Wed, 14 Oct 2009 01:32:29 GMT

It appears that your syntax for using vihostupdate is incorrect due to the error. Can you please provide the exact command you're using on the vCLI system... I don't think you mean to connect to 'localhost' as your ESXi host.

Here's an example of what params you should be passing to that command: http://www.vm-help.com/esx/esx3i/esx_3i_rcli/vihostupdate.php

Host Profiles question

bulletprooffool — Mon, 05 Oct 2009 09:14:35 GMT

You will need to do a very basic build on each of the other hosts, so that they can be added to the VC - you will not be able to use host profiles on the hosts until they are added to the VC - so these are manually specified at build time. the rest can come down from the template (You could .. if you really wanted to . . get additional storage ports and any other VMkernel ports to be assigned IP by DHCP)

vCenter - Query active triggered alarms

Debcha — Mon, 21 Sep 2009 17:25:47 GMT

Hi,

i would like to query the vCenter for any active triggered alarms (in my example Datastore Disk Usage/ Overallocation alarms) with powershell.

Is this possible ?

I'm not sure if "Get-VIEvent" is right (because it retrieves many/all events ?)

It is possible to detect if an alarm has acknowledged ?

Thanks for help

Thanks,

commands via the storage I can identify what the name of Mon Know kindly tell me in general what are the commands to remove and add the RDM?
Also with esx4 and 'can hook a physical HBA to a virtual machine? If this were the case would be fully resolved.
Thanks for your kind response to a.

remove last snapshot from command line

lamw — Fri, 28 Aug 2009 13:58:52 GMT

If you want to do this via the classic ESX Service Console, you can take a look into vimsh for your snapshot operation:

[root@himalaya ~]# vmware-vim-cmd vmsvc/snapshot.remove
Insufficient arguments.
Usage: snapshot.remove vmid [removeChildren] [snapshotLevel] [snapshotIndex]

Remove a snapshot on the vm.

I forget offhand which way the index level grows, you may want to do some testing but I think you just need to modify the last param snapshotIndex and it'll either start 0 and grow or the opposite value.

A more elegant solution is to use the vSphere SDK/VI SDK which allows you to just remove a particular snapshot by name RemoveSnapshot_Task() http://www.vmware.com/support/developer/vc-sdk/visdk400pubs/ReferenceGuide/vim.vm.Snapshot.html#remove but this will require you to run a script outside of the ESX Service Console on either a Windows/Linux or on vMA

Scripts after VM creation

lamw — Mon, 24 Aug 2009 14:09:55 GMT

You can take a look at VMware VIX: http://www.engr.ucsb.edu/~duonglt/vmware/#vmware_vix which allows you to execute commands within the guestOS, so long as you have VMware Tools installed. The current version 1.6.2 supports up to ESX 3.5, but not vSphere, I've heard the next version will fully support vSphere in case you were looking to deploy VMs on ESX(i) 4.0

You could also use Windows run once reg. keys and if you have the scripts stored in some shared accessible repository such as an NFS server, you could easily copy them over and execute them. I also think if you deploy from a template, you have an option in the customization to run custom scripts as part of the deployment, I'm not 100% sure but I believe that is the case for Windows.

Automating vMA installation

lamw — Thu, 20 Aug 2009 04:08:24 GMT

Well it's already pretty easy to deploy with a few clicks ... how many are you planning on deploying? I guess if you really wanted to, you could try to write something using PowerCLI or vSphere SDK for Perl, you can look into import vApp via .ovf and with vMA, there is a direct link from VMware at: http://www.vmware.com/support/developer/vima/index.html

http://www.vmware.com/go/importvma/vma4.ovf

From the release notes it's not a good idea to clone vMA ... and it probably won't work if you try to clone it but you could try and see if you can turn it into a template and then deploy and try to customize the image using vCenter. These are probably the ways I can think of in terms of automating a deployment of vMA, if it even works.
