Other than looking at Navisphere, how do I monitor my remote mirrors? I'm in the middle of switching over to MV/A from incremental SAN copy. My incrementals were done with Replication Manager so I "knew" when one of the replications would fail or have some sort of issue. I use SNMP to monitor the unit status (this is pretty generic but get the job done) of the Clariions...but I'm not sure if this will fire if I have an MV issue. Eons ago I think ControlCenter was sold to our firm but like many things was never implemented (nice..) - should I go down that path?
Another option would be to apply a distributed event monitoring template to the MV CLARiiON and set the template to send notifications to yourself or the appropriate email contacts when certain MV events occur. The settings can be upadated in the general tab of the template.
I will take a look at this and see how it goes - in the end, I'd also like to know how long the MV/A sessions are running and be able to graph these over time. I've got them set right now to 20 minutes after last successful session. If I knew how long they were taking, I might want to tighten this up a bit to reduce my RPO time or set them on a regular schedule of they start creeping into the same time interval. From what I can see running some navicli commands can return me some information and I can throw those into our monitoring system. The SNMP capabilities of the Clariion are either pretty weak or EMC hides their MIBs very well.
The only place I have been able to find the info about how long the previous sync took was in the gui. If you select properties on mirrorview session and select the secondary image tab it will tell you there. That same field doesn't seem to be available in naviseccli. I did submit a improvement case but obviously not sure if it will ever get implemented.

CLARalert and the templates I'm speaking of can be downloaded from Powerlink:
