Question

I wanted to extract a filerview from Net App commandlets, i wrote a an expression below

Get-NaLun | Select @{Name="LUN";Expression={$_.path}},@{Name="Size";Expression=     {[math]::Round([decimal]$_.size/1gb,0)}},`
@{Name="OnlineStatus";Expression={$_.online}},`
@{Name="Group";Expression={([string]::Join(",",(Get-NaLun $_.path | get-nalunmap | select -ExpandProperty initiatorgroupname)))}},`
@{Name="LunID";Expression={Get-NaLun $_.path | get-nalunmap | select -ExpandProperty lunid}} | Export-Csv "c:\LUN_FilerView.csv"

What i wanted is it possible to search based on the LUN ID, Initiator Group Name

if i can get a cmdlet

1. I would also like to run “Get-NaLUNbyMap” with a specific igroup map and LUN ID and have it respond with the LUN that is mapped at that LUN ID
2. Get-naLunByMap –igroup SEAPSQLPWS1_Cluster_Nodes – LunID 7

Can some one help me thanks!

here is the output of

PS 103 >  Get-NaLun /vol/Co4_I_UserDB

I think the Get-NaLunByIgroup cmdlet built in to the DataONTAP PowerShell Toolkit is what you are looking for:

PS C:\> Get-NaLunByIgroup xyratex 1

Path                                      TotalSize Protocol     Online Mapped  Thin  Comment
----                                      --------- --------     ------ ------  ----  -------
/vol/nicholsondev2k8/lun                    80.0 GB windows_2008  True   True   True

Also, you might take a look at Get-NaHostDisk and/or Get-NaHyperV for mapping Windows disks back to NetApp storage.
