new-sdlun

[david_taylor]

I am trying to script the end to end process of a new server build, setting up snap center, creating and connecting the default luns in windows.

Looking through the snap centre 2.0 cmdlet reference guide i have found all the commands I need and tested them separately however to create the lun it says to use new-sdlun

This doesn't appear to be part of the module that installs or any other netapp one I can find and i cannot find any more information on it, has any got any experience with this command?

New-sdvolume is there but no lun

any help appreciated

HI

i guess you also imported the Snapdrive module, correct?

i'm asking to dobule check because some PS commands are not integrated with SnapCenter itself, and the new-sdlun is one of them.

This is a command that belong to Snapdrive

With the latest release, SDW can be installed as integrated mode or standalone mode. in integration mode only the intergrated commands are allowed to be executed and other commands will show a an error "This command is not supported in Snap Center plugin mode".

You can enable these commands to be working by enabling then using commandlet

Set-StandaloneCommand.

Following are the example of enabling and disabling the commands not integrated with Snap center. 

Disable Command
Set-StandaloneCommand

Enable Command
Set-StandaloneCommand -Enable

Hello,

Sorry, I did leave out that important detail that i am getting the message on the snap center server itself 

New-SdLun : This command is not supported in SnapCenter Plug-in mode

Thanks for the info relating to this, I am not able to enable the command on the snap center server

PS C:\Windows\system32> Set-StandaloneCommand

Hi David

are you trying to do that on the plugin host or on the Snapcenter host?

anyway try to do in this way

import both modules, snapcenter and snapdrive

then open the connection with the command 

open-smconnection ..

instead the Set-StandaloneCommand use the following

set-sdsettings $true

and then

new-sdlun

let me know

Also, forgot to mention, you can use the new-sdstorage to provide LUN insted using the new-sdlun. this just to avoid all the previous mentioned steps and keep your script more tidy

new sd-storage is exactly what I needed - thank you!

Matte, why is there not a document that tells us all this.   The powershell support for Snapcenter is lacking not to mention the documentation.  Its fine to have a list of all the commands,  and the bare minimum of connection info, but I'm trying to cobble together provisioning a Lun, mounting it, etc but there is not how to for it.

The snapcenter powershell modules seem just like rebranded SnapManager & Snapdrive cmdlets that have to be run on a host instead of loading the module on mylaptop to command many systems from one..  Now in v4.1 of Snapcenter, I'd think powershell would have been more refined.

Is there any work being done to clean this up and make it easier and better documented?

Thanks,

Ray

Hello  RayHoltz,

we are not able to get new-sdstorage command.

Have you found a guide to use those cmdlet?
After running Open-smconnection and Import-Module SnapCenter, the Get-Command -Module SnapCenter not include the new-sdstorage or Set-SdSettings.

Any help is very appriciated.

Best regards

To use all the Sd* cmdlets you need to import the snapdrive module

ipmo snapdrive shoudl be enough is you have the windows plugin installed..

Hi Matte,

thanks for your suggestion.

If I understand corretcly we need to keep snapdrive installed on our system, correct?
Nowhere I have found that snapdrive is a requirement to use some function of snapcenter.

I have read that snapdrive is going to end of life and not needed anymore. I'm missing something?

I have tryed on another system where snapdrive still be present. Using the following commands

Open-smconnection -SMSbaseurl https://....  -Credential $cred -RoleName "SnapCenterAdmin"

Import-Module SnapCenter
Import-Module snapdrive

I can use the Get-SdStorage but using new-sdstorage I get "The term 'new-sdstorage' is not recognized as the name of a cmdlet".

Thanks a lot for your help.

Best regards

you should remove snapdrive, you’re right! The snapdrive PS module is part of the snapcenter windows plugin (They have the same name unfortunately) and you can find it in the plugin installation directory. 

Usually you just need to open powershell where the windows plugin is installed and run

>ipmo snapdrive

Matte you saved me.

Thank you for your help.

For anyone else with the same problem:

If you have previously installed Snapdrive on your system, you have to uninstall it and remove Snapdrive folder from C:\Windows\System32\WindowsPowerShell\v1.0\Modules.

One rebooted the system, you can point the following folder "C:\Program Files\NetApp\SnapCenter\SnapCenter Plug-in for Microsoft Windows" and executethe import-module snapdrive.

Ottimo 🙂

another think you should pay attention to is that if you already have installed the windows plugin along with the exchange one,  the best option would be to remove uninstall snapdrive and the windows plugin and then install SCW again.

This becase if you remove snapdrive it will also remove the data ontap VSS HW provider and this can create trouble if you have to use VSS for backup.
