Have a look at Orphaned Files Revisited

[Narayanan_5245]

Thanks LucD for the reply. I have tried this by saving it as Get-vmOrphan.ps1 and executed after connected to vCenter server, getting no output, and completing quickly

Is there anything i am executing the function incorrectly. Please advise.

Did you actually call the function in your .ps1 file?
The Sample Usage in that post shows how to call the function.

[Narayanan_5245]

Kindly find below the output which followed the sample usage in the post.

PS C:\temp> Connect-VIServer vCenter01.globedev.com

Name Port User
---- ---- ----
vCenter01.globedev.com 443 root

PS C:\temp> .\Get-VmwOrphan.ps1
PS C:\temp> .\Get-VmwOrphan.ps1 -Datastore HDS-DEV-Vgstore
PS C:\temp>

That is not in the sample usage.

In the .ps1 file you copy the function, then at the end, you add one line where you call the function.

# Copy the function here

Get-VmwOrphan -Datastore HDS-DEV-Vgstore

[Narayanan_5245]

Hi LuCD

Copied the script into notepad and saved it as .ps1 file and add the last line (Get-VmwOrphan -Datastore HDS-DEV-Vgstore) which you suggested as well.

Connected the vCenter server. But it completes quickly and no output. Please advise if I executed incorrectly..

Can you attach your script?

[Narayanan_5245]

Thanks for reply. PFA for your reference.

Is that a VSAN datastore?

[Narayanan_5245]

Hi LuCD,

No vsan datastores available in the environment.

All the datastores are configured with VMFS 5 version in the vCenter server.

I have tried with multiple datastores names & wild card asterisk as well.

Ok, can you try with the attached script?
That is my older version of the script.
Although the function is called Remove-OrphanedData, it will not remove any files unless the Delete switch is used.

[Narayanan_5245]

Thanks LuCD for checking. 
I have tried with the new script (script.ps1) which you attached and got the same with no output after connected to the vCenter, didnt throw any error as well.
Made a few of the vmdk disks unattached (removed from vm) in that datastores for testing as well.

Seems something I am missing.

Narayanan.

Can you add the Verbose switch on the function call?
That function has verbose messages that could help to clarify what is happening.

[Narayanan_5245]

Hi LuCD,

Tried with a verbose option at the end of the line and got the below output. I could see you already added write-verbose in the function of the script.

PS C:\temp> .\script.ps1
VERBOSE: 4/6/2021 5:26:09 AM Get-View Started execution
VERBOSE: 4/6/2021 5:26:09 AM Get-View Finished execution
VERBOSE: 4/6/2021 5:26:09 AM Get-Datastore Started execution
VERBOSE: 4/6/2021 5:26:09 AM Get-Datastore Finished execution
VERBOSE: DS: HDS-DEV-Vgstore
VERBOSE: MultiHost: False
PS C:\temp>

Please advise.

Thank you

The datastore doesn't seem to be a shared datastore.
Hence the function skips the check.

[Narayanan_5245]

ah..ok. you are right LuCD. 

just noticed the datastore LUNs are not presented to other hosts in the cluster.Let me try in different vCenter server where the datastores are shared across the hosts.

Is this possible to query all the VMFS datastores in the vCenter server except NFS and report orphaned vmdks?

Regards

Narayanan.

[LucD]

Yes,  but to exclude NFS datastores, you will have to change the line

if ($ds.ExtensionData.Summary.MultipleHostAccess) {

into

if ($ds.ExtensionData.Summary.MultipleHostAccess -and $ds.Type -eq 'VMFS') {
