PowerShell Module

I hope to have the V2 module released soon. Waiting for the devs to get back to me on some volume collection stuff, been having a hard time getting that to work.

Kelley Underwood,

Here is my script that i have just written. It has been tested and it worked but it needs more testing. It isnt perfect and has lots of room for improvement.

What we are doing is cloning 3 drive to 3 new drive on the same server (dont ask...).

## This script could be setup on Server1 or from another server that has the nimble powershell module installed

#running the script locally will not require any credentials to be stored in the script (except for the nimble account)

## Remove a disk from Windows

set-disk -Number 14 -IsOffline $true

Write-Host "Connecting you now....."

Also, some things that i found during this work...

the new-nsvolume command has some trouble with creating new volumes where the name is a certain length. Not sure what that length is but during my work i wanted to use Clone-ap-nimble-vol060-Server1-G-drive but it would throw a wierd SMEintval error.

In the ## clone the snapshot into a new volume section (line 54), using the Get-NSSnapShot -SnapName $VDW doesnt work and i have had to explicity name the snapshot. You can remove the variables from the #Take a snapshot of a volume section.

Also i would like to see if someone could help write a module to rename a snapshot. We want to keep a few snapshot for recover purposes so renaming the snapshot would be cool.

And i would like to get some other things added to this script such as;

error checking

more logic to make sure it selects the right disks to present or delete. Right now it works and it is solid but if we add a new disk to the server then we need to update all of the disk number in the script.

Getting some form of HTML report created so we can send this to the Data owners and IT support on the weekly schedule.

If you have any recommendations for other improvements please share. I am still working on this as well and if i can get past some of these items i will also update.

I'm having issues logging to Nimble via PS. Any ideas:

PS P:\> Connect-NSArray -SystemName 192.168.1.80 -Username [MYUSERNAME] -Password [MYPASSWORD]
Exception calling "getGroupConfig" with "2" argument(s): "There is an error in XML document (2, 1417)."

If I do not specify my username I get this:

Has anyone else come across this? I appear to have successfully imported the module:

hi

is it possible to take a nimble snapshot and add it to a volume collection at the same time so the snap is managed?

thanks

mark
