Seperate push2tape into two scripts – Originally posted By quentin, 18 Mar 2011

quentin - I was tasked with using this excellent script to assist in our backup process. I would like to seperate this into two scripts for use with BackupExec 2010 R2's pre and post job setting. I am quite new to powershell and cannot seem to figure out how to get the information necessary from the pre script to unmount and delete the replay view that my pre script creates. Would one of you fine folks mind giving me a quick example of how i could split the default push2tape script into two?. All assistance is very much appreciated.

CIS - We tasked a contractor to do this, and he did it by naming all of the variables (server name, volume name, mount path) with an "X" in front of them and exporting these variables with this command:  "Get-Variable X* |Export-Clixml variables.xml" where "variables.xml" is the filename to store the variables.  The second script - which dismounted the volumes - included a command "Import-Clixml .\variables.xml | %{ Set-Variable $_.Name $_.Value }" which read the exported variables from the first script.

Compellent Co-pilot support was very helpful with this as well; I can send you an example of a modified push2tape script that I'm currently testing to do exactly what you are attempting to do if you'd like, or you can contact them directly for assistance.  Keep in mind I'm not knowledgeable of powershell either; that's why we hired a contractor to assist :)

Hope that helps.

quentin - Wonderful!, would you mind sharing your scripts with me?. That would be great.

CIS - I don't see any way to attach anything, so here they are; let me know if you can't read them.  Also, you'll have to modify some of the variables for your environment, as well as the IP address of the storage center (which I've changed to xx.xx.xx.xx to protect the innocent :)), and you may have to adjust the $pass line depending upon how/where you've stored the Storage Center password.  Finally, keep in mind that I'm still testing these; they don't work consistently in my environment yet - sometimes the volume drive letter shows up in Windows, sometimes not - but they work for Compellent so there's hope that they may work for you.

  quentin  - This is exactly what I needed. Thank you so much!. Great example.

  quentin  - This was done in Command Set 5?. 6 doesn't seem to like the .Index and -Index. Any idea on how to go about the mapping and removing in 6?

  bmiddauch - All of the changes from Storage Center Command Set 5.0 to 6.0 are documented in the Storage Center Command Set 6.0 for Windows PowerShell User Guide available from the Knowledge Base.

 

The changes in the actual scripts are:

5.0 used this command for the Snap-in: Add-PSSnapin Compellent.StorageCenter.Scripting

 

6.0 uses this command for the Snap-in: Add-PSSnapin Compellent.StorageCenter.PSSnapin

 

In sample scripts 5.0 used:

$replayview = New-SCVolume -SourceReplay $latestreplay -Name $newreplayname

 

New-SCVolumeMap -VolumeIndex $replayview.Index -ServerIndex $scserver.Index -SinglePath

 

Remove-SCVolume -Index $replayview.Index -SkipRecycleBin -Confirm:$false

 

In sample scripts 6.0 used:

$replayview = New-SCVolume -SourceSCReplay $latestreplay -Name $newreplayname

 

New-SCVolumeMap -SCVolume $replayview -SCServer $scserver -SinglePath

 

Remove-SCVolume -SCVolume $replayview -SkipRecycleBin -Confirm:$false

 

In 5.0 sample scripts were installed here by default:
