Powershell Script to Create Clone, Mount Clone

smilerspeaking136 — Mon, 22 Jul 2013 10:22:59 GMT

G'Morning,

Does anyone have a script or point me in the right direction for the following script/tool.

## Microsoft OS requirement ##

Select a Volume Snap
Create a Clone
Mount Snap

With NetApp's Snapdrive - it is posisble to select a snapshot of a LUN and mount that at another drive letter.

I know this is all possible manually, just very tedious task when trying to restore data.

If not I'll work on it myself

Thanks

Sparkles

Hi Justin, is there any documentation about what those scripts do and how to use them? Thanks. I'm looking for something similar as Mike asked but I'm no expert on power shell scripting.

Sorry I have not had time to populate the docs. I've tried to create all of the functions in a very standard way.

If you tell me what you're trying to do i could provide the code you'd use.

Also I should in the next week or so have time to get back on top of this, I need to add "volume collections" and populate the docs and then i'll have the majority of the gui functionality implemented.

Jason - there is a rather excellent introduction tutorial here

Many of the things Justin is using in his rather excellent scripts is also covered in that tutorial.

Hope this helps

basically I'm looking for scripts to make restoring data easier. Just like Mike said, clone a volume from a snapshot, give access permission of that volume to a server, connect to the volume using iSCSI in the server. Thanks.

Those are all in the module, have you loaded it successfully?

You have to connect first, but you can get a list of all functions by running the following command.

gcm -Module nimble

That will return about 18 functions. the names are pretty self explanatory..

You can use tab to help complete things, for example if you do

get-nsvolume -<tab>

You can then tab through the different parameters.

I would suggest using powershell ISE to start since the intellisense will really help.

This was created in powershell 3 but should be compatible with 2, however i strongly suggest you use v3.

I've tried to add a good deal of protection to any remove command, but, like anything else, be careful with what you do.

in your case, are you talking about taking a snapshot that you have already and converting it in to a close and setting access? Is the snapshot from a protection plan?

Hi Justin, I tried the gcm –Module nimble command and it returns nothing. I copied all the scripts into my powershell profile and the folder is named nimble. I’m running Windows 8 which is powershell version 4. Does that matter? Thanks.

Re: Powershell - create clone, mount clone

jrich52352 — Thu, 25 Jul 2013 15:16:10 GMT

so you'll want to copy all of the files (and unblock them) to

my documents\windowspowershell\modules\nimble

dump all the files in that folder and then from powershell type

import-module nimble

gcm -module nimble

also, V4 is currently only with Windows 2012 R2 and as a CTP download. however if you do have it, it will work fine.

I did try the import command and here’s what I got:

Import-Module : Could not load file or assembly

'file:///C:\Users\admin\Documents\WindowsPowerShell\Modules\nimble\GroupMgmt.dll' or one of its dependencies. Operation

is not supported. (Exception from HRESULT: 0x80131515)

jrich52352 — Thu, 25 Jul 2013 15:26:35 GMT

this is from the Win8 box?

if you type in $host what do you get? It should say its V3. if its V2 then its possible that the groupmgmt.dll might be compiled for .net 4.0 and since powershell V2 is .net 2.0 that might cause an issue.

also did you unblock the files? that might also cause it

you can do, in V3

gci "$(split-path $profile)\modules\nimble" -r | Unblock-File

That was on a Windows server 2012 datacenter which has version 3. I confirmed it by running get-host command. The files have been unblocked too.

Re: Powershell - create clone, mount clone

jliu79 — Thu, 25 Jul 2013 15:52:00 GMT

One thing I noticed is you said groupmgmt.dll might be compiled for .net 4.0 but I only have 4.5 on my Windows 8 and Windows server 2012. That might causing the issue?

Re: Powershell - create clone, mount clone

jrich52352 — Thu, 25 Jul 2013 16:26:10 GMT

try doing this, go to the folder that contains the files (nimble folder) and type this

add-type -Path .\GroupMgmt.dll

also, im not sure if this matters,but do you run it elevated? i have mine set to by default.

Re: Powershell - create clone, mount clone

jliu79 — Thu, 25 Jul 2013 17:11:12 GMT

Thanks Justin. Running add-type command fixed the problem.

Thats kind of odd since essentially thats what the import-module is doing.

I did stumble across this yesterday - after getting wound up using disk part, new PS modules should be able to cover the requirements for disk part when mounting a clone.

http://swodniw.wordpress.com/2012/10/12/powershell-cmdlets-one-by-one-or-how-to-replace-diskpart-with-powershell/

I'll be looking into this in a week or so.

Re: Powershell - create clone, mount clone

jrich52352 — Fri, 26 Jul 2013 15:24:13 GMT

yeah 2012 is awesome with its cmdlets... we're making a push to get to 2012 for this reason. however you can feed stuff to diskpart fairly easily..

$id = gwmi win32_diskdrive -ComputerName $ComputerName -Credential $Credential -Filter "model LIKE 'vmware%'" | sort @{e={(($_.size /1gb) / $size)%1}},index -Descending |select -first 1 -exp index

$dpscript = @"

select disk $id

online disk noerr

convert gpt noerr

create partition primary noerr

assign letter=$letter

FORMAT FS=NTFS UNIT=64k QUICK Label=SQL

$job = Invoke-Command -ScriptBlock {$args[0] | diskpart} -Session $session -ArgumentList $dpscript

I use this as part of my Add-DriveToVm

I've just got the following to work - (Remove "write-host" from the "foreach" line **or leave in to see what its going to do **):

### get Nimble disks ###

$nimbledisks = get-disk | Where {$_.Manufacturer -like "Nimble*"} | select -expandproperty "number"

### Remove readonly ###

write-host "remove readonly atribute from disks > $nimbledisks" -foregroundcolor yellow

foreach( $disk in $nimbledisks ){ write-host set-disk -number $disk -isreadonly 0}

write-host "Disks > $nimbledisks -> writeable" -foregroundcolor green

### Remove offline ###

write-host "remove offline atribute from disks > $nimbledisks" -foregroundcolor yellow

foreach( $disk in $nimbledisks ){ write-host set-disk -number $disk -isoffline 0}

write-host "Disks > $nimbledisks -> online" -foregroundcolor green

Next I need to work out assigning drive letters, holiday first though
