Parameter(s) for Post-Replication Script?
In a virtualizing environment, I am looking to do the following:
- create a replica (in this case, it is a CLARiiON Snapshot Snap)
- after the replica completes, execute a script to make the newly created snapshot session available to a virtual server
The conundrum I am trying to solve is how to identify the snapshot session; in the RM documentation it talks about XML files existing for application callout scripts, but I didn't see a similar option for a post-replication script.
Is it possible to get RM to indicate what storage was just created?
thanks,
Frank

Interesting idea.
There would be a few ideas in figuring out what storage was just created. Getting this information to a script in a digestible format is the trick.
You could use RMCLI to pull what the latest snapshot is from that source LUN(s)
eg
/Storage/CKM000XXX00063/RMSERVER-0075-1152
/Storage/CKM000XXX00063/RMSERVER-0075-1280
/Storage/CKM000XXX00063/RMSERVER-0075-1333
Say 1333 (a number generated by the RM database), then parse that number in the list of snapshots via NaviSecCli and then present that to the ESX server?

thank you for the response. I was thinking along the lines of using RMCLI to get the information, but struggled with a good method for ensuring that this is indeed the correct snapshot. My concern is that in an environment where a number of snapshots are taken close together (i.e. it's time to start the backup jobs), it may be impossible to guarantee that I have the right one, in which case I could be exposing someone else's data to the virtual server.
I'd welcome your thoughts on this,.
thanks,
Frank
