Check if DataStore is detached from host

[sennaf2]

I have migrated all my VMs to new VMFS6 datastores after upgrading vCenter.  I have placed all the VMFS5 datastores in maintenace mode and unmounted all.  The last thing I need to do is detach each from all the hosts.  I found a script to detach the LUN from the hosts, but I want something to show me hosts still attached if the detach script missed one.

I have tried to find where this value is but I can not find it. 

Here is what I have tried

$esx = Get-VMHost -Name 'esxi01.MyDomain.com'

$storSys = Get-view $esx.ExtensionData.ConfigManager.StorageSystem

$storSys.StorageDeviceInfo.ScsiLun | where {$_.CanonicalName -eq 'naa.xxxxxxxxxxxxxxxxxxxxxxxxxxx'}

--and--

$ScsiLun = Get-ScsiLun -VmHost $esx -LunType disk | Where-Object {$_.CanonicalName -eq 'naa.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'}

But I can not find where this property is.

Thanks in advance for any help.

Wrong sub-forum. Move to PowerCLI.

[LucD · Accepted solution]

One way to check is with esxcli.

See if the device appears in the list of detached LUNs

$esxName = 'MyEsx'

$esx = Get-VMHost -Name $esxName

$esxcli = Get-EsxCli -VMHost $esx -V2

$esxcli.storage.core.device.detached.list.Invoke()

[sennaf2]

LucD Thanks for the help.  My scrip is working but for some reason it is not clearing the old LUNs after I remove them from the storage array and rescan storage in vmware?

I have also modified it slightly to search all hosts.

Here is my modified script.

Clear-Variable -name esx

Clear-Variable -name esxhosts

Clear-Variable -name esxcli

#$esxName = 'MyEsx'

$esxhosts = Get-VMHost

Foreach ($esx in $esxhosts){

$esxcli = Get-EsxCli -VMHost $esx.Name -V2

Write-Host $esx.Name

$esxcli.storage.core.device.detached.list.Invoke()

}

But the output is this

PS C:\EQR\Detach Datastore> C:\EQR\Detach Datastore\checkdetachAllHosts.ps1

I have completely remove naa.60000970000197901057533030303243 from vSphere and Storage.  The UUID is not present in the vSphere webclient 6.7 but displays in this script?

Did you rescan storage and HBA?
From the Web Client or through an esxcli command?

[sennaf2]

I did not think it made a difference.  I originally scanned from the 6.7 WebClient.  When I saw this thread I ran it from PowerCLI and have the same results.

Here is the command I ran.  Thanks to Andreas Lesslhumer on https://www.running-system.com/

Get-Cluster ‘name_of_your_cluster‘ | Get-VMHost | Get-VMHostStorage -RescanAllHba -RescanVmfs

[LucD]

Can you try like this?

$esxcli.storage.core.adapter.rescan.Invoke(@{all=$true})

[sennaf2]

I added it to the script as the first command after ForEach and it still shows them all.

Clear-Variable -name esx

Clear-Variable -name esxhosts

Clear-Variable -name esxcli

$esxhosts = Get-VMHost

Foreach ($esx in $esxhosts){

$esxcli.storage.core.adapter.rescan.Invoke(@{all=$true})

$esxcli = Get-EsxCli -VMHost $esx.Name -V2

Write-Host $esx.Name

$esxcli.storage.core.device.detached.list.Invoke()

}

[LucD]

That line should go after the Get-EsxCli line.

Could you also check if you see that LUN as a greyed-out entry in the Web Client after the detach?

That entry should disappear after a rescan of the HBA

[sennaf2]

I moved the line to below the Get-EsxCli, ran the script and received the same result.

I logged into the web client the device was there and grayed out and showed detached.

I scanned the storage from the Web Client and it still appears in Storage Devices.

Once I remove the device from the storage array it disappears in the gui but not the script.

Thanks for all your help with this. 

It is working but when I run the script there are more and more entries which makes it harder to distinguish what is detached.

I suspect the Web Client doesn't show the LUN when the Status is 'off'.

I suspect a script should follow the same concept.
