The situation:
I have 2 sans (brand is: Stonefly Optisan).
on both san's I create a target.
I have 1 server. the recieves the targets from both san's.
next the server does a raid1 on the two iSCSI disks.

The problem:
When I add a new target on the SAN it has to do a iSCSI reset. If I do
this the server drops the connection to the san, the raid1 is broken.
And I have to add the iSCSI disk to the raid set again and sync.
The question:
Does anybody here have a idea how to prevent the raid from dropping
the disk and having to rebuild again?
Maybe I can adjust some timers? I have been searching a lot, but I am
unable to find anything.
please help!

The TL;DR version.

DO NOT RUN SOFTWARE RAID OVER iSCSI OR ATAOE EVER. IT DOES NOT WORK.
 
I'm assuming your using this configuration as a poor mans way of replicating data between the SANs. Let me guess, the SANs are in two different locations right?

If I were you I would look into another solution like DoubleTake, NeverFail, or the like if your SAN management tools don't provide a means to replicate data.
