Disable few paths from ESXi hosts which part of one Cluster

[iamshivaji]

Hi,

We are doing a storage port re-balancing and as part of that i want to disable FEW storage paths from each ESXi from ONE ESXi host cluster as the storage team assigned new storage paths to the same set of LUN's. I could see all new paths now. Storage team want to pull back the old paths. I want to disable the old paths from a set of ESX Hosts(part of same cluster) before storage team pull back the paths.

I have 60 paths for each HBA and 2 HBA's for each ESXi host  which makes a total of 120 paths. Storage team gave the storage path information which i have to disable and i could see them on each HBA.

I tried doing it from powercli script but for some reason it is not working.

We are using ESXi 5 Update 3.

Is there an easy way to do this without manually disabling 120 times for ESXi host?

Would you mind sharing the script you used, and the eventual messages it produced ?

[iamshivaji]

LucD,

I dont get any output.

$tgtHBA = "vmhba2"

$tgtPortWWN = "5764617912562315608"

Get-VMHost | Get-ScsiLun -LunType disk | where {$_.RuntimeName.Contains($tgtHBA)} |Get-ScsiLunPath | where

{$_.Extensiondata.Transport.PortWorldWideName -eq $tgtPortWWN} |Set-ScsiLunPath -Active:$false

Here is the link i followed. This was updated by you in 2011 🙂

From where are you running that script ? From the PowerCLI prompt ?

Any error messages ?

Which vSphere and PowerCLI version are you using ?

Just ran that script, and it seems to work without a hitch for me.

The script should output something like this (the State property is the one to watch for)

[iamshivaji]

Ok. Good.

I have PowerCLI 5.1 release 1 and ESXi 5.0.0, 1311175

Can you please share me the exact script.

[iamshivaji]

I am running the script from vCenter server.

i am using powerCLI from vCenter server. I dont see any tasks getting created and no output in the prompt. Attached the screenshot and the script.

Ok, I think I know what happens.

You placed that script in a PS1 file, correct ?

You seem to call the PS1 file from the PowerCLI prompt, but it looks as if you typed "<dot><blank>\disable_paths.ps1".

Is that correct ?

If the PS1 file is stored in the folder where you are located (C:\Scripts\PowerCLI\Shivaji), then you should type

.\disable_paths.ps1

at the PowerCLI prompt. No blank between the dot and the back-slash.

[iamshivaji]

yes it is a PS1 file but there is no blank in between dot and back-slash.

Is your PowerShell execution poicy set correctly ? Do a

Get-ExecutionPolicy

Are you connected to a vSphere server ? Do a

$global:DefaultVIServer

[iamshivaji]

Get-ExecutionPolicy shows unrestricted

$global:DefaultVIServer shows my vCenterServer.

[LucD]

Then I'm afraid I'm at the end of my ideas.

The only thing I could suggest, try to execute the lines in the PS1 file, one by one directly from the PowerCLI prompt.

Curious to see if that works.
