I just wanted to chime in with another potential option, with regards to the " For a workflow example, before removing the volume, is there an OPTION we can offline the volume for a period of time, say 24 hours, or X, then destroy the vol? " question.
First off the option sinhaa provided is totally valid.
An alternative is very similar to what was recommended:
clone an applicable workflow
edit the new workflow and add an "Approval Point" between the 'Vol Offline' command and the 'Vol Delete' command.
This allows you the flexibility to wait as long as you require (as a WFA Workflow Approver) to confirm there are no issues before 'approving' and 'resuming' the workflow to delete the applicable volumes for deletion in the workflow.
Please let us know if you require any additional information.
Couple things. Awesome "FREE" training video for overview on WFA! I can't tell you how cool it was to see the options now that are now possible with dropping and dragging functions around. At 1st, I was like, yeah, yeah, but now, WOW.
Maybe something that would be "Cool" would be to have a GUI view of the aggr for usage, and maybe colors for latency/IO usage with creating/adding vols, etc. I know WFA is really a shell and you go and do what you want, but I can see how this is REALLY applicable in a large CM environment.
Maybe more videos or demos on doing your own templates. Very cool guys AND gals!!!
