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
