Hi Jean,
Pls find my responses inline.
- Is it possible to get the history of snapshots with their sizes for a specific volume or aggregate?
Did you try the snapshot reports ? Can you give me some example of what you are looking for ? So that I can tell you if that is possible with OCUM or not.
- Can we setup an alarm different than the threshold for a specific volume?
By alarm you mean alarm for the snapshot usaage ? If so yes we already have one.
[root@vmlnx ~]# dfm options list | grep -i volsnap
volSnapshotCountThreshold 250
volSnapshotFullThreshold 90
volSnapshotTooOldThreshold 52 weeks
[root@vmlnx ~]# dfm eventtype list | grep -i df.snapshot.kbytes
snapshot-full Warning df.snapshot.kbytes
snapshot-space-ok Normal df.snapshot.kbytes
[root@vmlnx ~]# dfm eventtype list | grep -i old-snap
snapshots:not-too-old Normal old-snaps
snapshots:too-old Warning old-snaps
[root@vmlnx~]#
