Get-NcLun - Find/List lun by specifying serialnumber

[donn]

Trying to figure out the capabilities (How do I use it) of the Get-NcLun -Query command.  My goal is to match/find a lun by specifying the serial number.  I can't figure the command line syntax for this -Query option.  Is anyone familiar with the correct syntax?  Thanks

-Query <LunInfo>

     For advanced queries, provide a LunInfo object with various fields set to indicate which records to retrieve.

     Other fields should remain set to null.  Use "Get-NcLun -Template" to get the initially empty LunInfo object.

More Info:

PS C:\Users\administrator> Get-NcLun | get-member

I guess you can just do simple powershell pipe lining to get the output

An example below.

Get-NcLun | ?{$_.serialnumber -eq "-dPw6$8rC3rz"}

[beam · Accepted solution]

You can use the -Template switch on Get-NcLun to get an empty LunInfo object.  Then you set the fields to the values you want to query on the LunInfo object, leaving the other fields null.  For example, to get a specific LUN by its serial number:

PS C:\Users\Administrator> $query = Get-NcLun -Template

PS C:\Users\Administrator> $query.SerialNumber = '7T5G6+3iH8Qa'

PS C:\Users\Administrator> Get-NcLun -Query $query

Path                                           Size Protocol     Online Mapped  Thin  Vserver              Comment

----                                           ---- --------     ------ ------  ----  -------              -------

/vol/clusterdisks/disk0                    200.0 GB windows_2008  True   True   True  beam01

If you are using PowerShell 3, you can do this in one line:

PS C:\Users\Administrator> Get-NcLun -Query @{SerialNumber='7T5G6+3iH8Qa'}

Path                                           Size Protocol     Online Mapped  Thin  Vserver              Comment

----                                           ---- --------     ------ ------  ----  -------              -------

/vol/clusterdisks/disk0                    200.0 GB windows_2008  True   True   True  beam01

You can also build more complex queries, such as this one to get all online, mapped, and thin LUNs that are bigger than 200GB:

PS C:\Users\Administrator> Get-NcLun -Query @{Online=$true; Mapped=$true; Thin=$true; Size=">$(200GB)"}

Path                                           Size Protocol     Online Mapped  Thin  Vserver              Comment

----                                           ---- --------     ------ ------  ----  -------              -------

/vol/clusterdisks/disk0                    200.0 GB windows_2008  True   True   True  beam01

/vol/clusterdisks/disk1                      1.0 TB windows_2008  True   True   True  beam01

/vol/powershell/luns/cluster                 1.0 TB windows_2008  True   True   True  beam01

/vol/powershell/luns/disk0                   1.0 TB windows_2008  True   True   True  beam01
