Stormagic Mirror unsynchronized

We  had a hard drive failure on one of our servers and it has then came up.  We have two stormagic iSCSI appliances and they have a message that says plex state "unsychronized" on one side of the mirror and on the other it says Plex has storage marked as failed.   After the server hard drive was fixed it had the message about the mirror  not being synchronized.  And now things keep failing, and VMs are crashing.   How do I get the mirror synchronized again?  Do I  need to bring all of the VMs and servers down?  We currently run 10 ESXi servers.  Thank you!

Mirror unsynchronized means failure of half of mirror.
Recurring crashes means that actually master was one that failed too, so data has been lost (tm)

It is hard to understand your topology unless you draw a diagram.
Where is a mirror? VM with 2 disks mirrored? iscsi drive mirrored? mirroring in RAID controller? Mirroring between storage units?

Did you tried breaking the mirror and recreate it?

I was able to recreate it and then I  had to rescan the iscsi adapters on each ESXI host to get it connect again.

I had to break the "plex" from the side that was unsychronized and delete the pool.  Then I went to the good side and added the target back to the mirror and added that pool.  It took about 4 hours to resync.  Then i went to each ESXI host and rescanned the iSCSI adapter and that made them reestablish the sessions.
