Followup, my initiator did eventually panic. I will have to do some setup to get a ZVOL from another system to mirror with, and see what happens when one of them goes away. Will post in a day or two on that. This message posted from opensolaris.org __

I don't think ANY situation in which you are mirrored and one half of the mirror pair becomes unavailable will panic the system. At least this has been the case when I've tested with local storage haven't tried with iSCSI yet but will give it a whirl. I had a simple single ZVOL shared over iSC

If you have a mirrored iscsi zpool. It will NOT panic when 1 of the submirrors is unavailable. zpool status will hang for some time, but after I thinkt 300 seconds it will put the device on unavailable. The panic was the default in the past, And it only occurs if all devices are unavailable.
