PowerCLI for SCSI Unmap

[varun11babu]

Hi,

I am getting following error while performing powerCLI, i assume it's still running in the back ground, but would like to know what is causing this error.

The operation has timed out

At <Location>.ps1:21 char:1

+ $esxcli.storage.vmfs.unmap.Invoke($arguments)

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : OperationStopped: (:) [], ViError

    + FullyQualifiedErrorId : VMware.VimAutomation.Sdk.Types.V1.ErrorHandling.

   VimException.ViError

Any inputs will help. The ESXi running in 6.0 Update3 and powercli is 6.5

Out of 85 data stores, it succeeds on 74 and fails on 11 with above error

An unmap can go on for a rather long time.

The default timeout is 300 seconds, you are probably hitting that timeout with those LUNs.

Try disabling the timeout, and see if that makes a difference.

Set-PowerCLIConfiguration -WebOperationTimeoutSeconds -1 -Scope Session -Confirm:$false

You can also verify VAAI stats in ESXTOP to make sure that you "only" hit the timeout that LucD mentioned.

I had defined weboperationtimeoutseconds to 600. But let me set that to -1 and try that..

So far it's working without any errors that i encountered earlier.

Also for the 11 that had errors earlier?

Yes, It did fixed all the 11. I think it was the weboperationtimeout parameter causing it..
