PSTK: Combine the output of Get-NcLunMap and Get-NcIgroup - custom object?

tyrone_owen_1 — Wed, 04 Jun 2025 10:32:39 GMT

Hi,

So I want to combine the output from the following two cmdlets:

Get-NcLunMap | Select-Object Vserver,Path,InitiatorGroup,LunId Get-NcIgroup | Select-Object InitiatorGroupAluaEnabled,InitiatorGroupOsType,InitiatorGroupType,Initiators

I've been looking at the Don Jones video, https://www.youtube.com/watch?v=TLUzPvA0HUo&t=42s, and I think I need to create a custom object. The cmdlets in the video return a single item, e.g. for a particular computer the Win32_OperatingSystem, however Get-NcLun/Igroup returns all of the LUNs/Igroups from a cluster. I can see how the Don Jones example would work for a single item but I don't understand how to upscale that when there are multiple objects returned.

Also as an aside, is there any way I can get an online/offline status for initiators into my completed table?

As you can probably tell, I'm a novice, any thoughts please?

Thanks

So after a bit more research I came across this approach, however it still doesn't get me what I want:

function Get-CgiNcLunMapInfo () { $lunmapinfo = Get-NcLunMap $igroupinfo = Get-NcIgroup # Create custom object for $lunmapinfo # Empty array $lunmapinfoobjs = @() # Loop to set up a single custom object foreach ($lun in $lunmapinfo) { $props = @{ Vserver = $lun.Vserver Path = $lun.Path LunId = $lun.LunId Igroup = $lun.InitiatorGroup } $lunmapinfoobj = New-Object -TypeName PSObject -Property $props # Append to array $lunmapinfoobjs += $lunmapinfoobj } # Create custom object for $igroupinfo # Empty array $igroupinfoobjs = @() # Loop to set up a single custom object foreach ($igroup in $igroupinfo) { $props = @{ Igroup = $igroup.Name Alua = $igroup.InitiatorGroupAluaEnabled OsType = $igroup.InitiatorGroupOsType GroupType = $igroup.InitiatorGroupType Initiators = $igroup.Initiators } $igroupinfoobj = New-Object -TypeName PSObject -Property $props # Append to array $igroupinfoobjs += $igroupinfoobj } $props = @{ LunInfo = $lunmapinfoobjs IgroupInfo = $igroupinfoobjs } $obj = New-Object -TypeName PSObject -Property $props Write-Output $obj }

The above script pushes the Get-NcLunMap objects/properties under the heading 'LunInfo' and the Get-NcIgroup objects/properties under the heading 'IgroupInfo', whereas I want to combine the properties into a single table, e.g.

Path,LunId,Igroup,Vserver,Alua,Igroup,OsType,GroupType,Initiators

Thanks

Hi:

Check the attached document. It includes example code.

Hope this help!

OntapLuninfo.ps1 vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 0 comp-01a mixed vmware True /vol/SERVER_DATASTORE/SERVER_DATASTORE Initiator Online --------- ------ iqn.1998-01.com.vmware:comp-01a-62411b9cdd7438fb True iqn.1998-01.com.vmware:comp-02a-92411b9cdd7438fb False iqn.1998-01.com.vmware:comp-03a-42411b9cdd7438fb False iqn.1998-01.com.vmware:comp-04a-52411b9cdd7438fb False vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 2 comp-01a mixed vmware True /vol/SERVER_DATASTORE_VVOL_1/vvolPE-1614476525287 Initiator Online --------- ------ iqn.1998-01.com.vmware:comp-01a-62411b9cdd7438fb True iqn.1998-01.com.vmware:comp-02a-92411b9cdd7438fb False iqn.1998-01.com.vmware:comp-03a-42411b9cdd7438fb False iqn.1998-01.com.vmware:comp-04a-52411b9cdd7438fb False

That's brilliant - thank you

I've played around with the script to try and get a single table as opposed to individual tables per LUN path, something like this:

vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 2 comp-01a mixed vmware True /vol/SERVER_DATASTORE_VVOL_1/vvolPE-1614476525287 SAN 0 comp-01a mixed vmware True /vol/SERVER_DATASTORE/SERVER_DATASTORE SAN 0 comp-01a mixed vmware True /vol/SERVER_DATASTORE/SERVER_DATASTORE2

Can the script be tweaked to achieve this?

Thanks again

only need to change one line of the code. put a # in front of:

#Write-Output $initiatoronline

Thank again for your help

I thought that, but the output looks like this instead of consolidated under one heading:

vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 2 comp-01a mixed vmware True /vol/SERVER_DATASTORE_VVOL_1/vvolPE-1614476525287 vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 0 comp-01a mixed vmware True /vol/SERVER_DATASTORE/SERVER_DATASTORE vServer Lun ID IGROUP Name IGROUP TYPE IGROUP TYPE OS IGROUP ALUA ENABLE Lun Path ------- ------ ----------- ----------- -------------- ------------------ -------- SAN 0 comp-01a mixed vmware True /vol/SERVER_DATASTORE/SERVER_DATASTORE2
