zfs discuss - Feb 2010 - disks in zpool gone at the same time

Hi,

Yesterday I got all my disks in two zpool disconected.
They are not real disks - LUNS from StorageTek 2530 array.
What could that be -  a failing LSI card or a mpt driver in 2009.06? 
After reboot got four disks in FAILED state - zpool clear fixed
things with resilvering.

Here is how it started (/var/adm/messages)

Does anyone have any problem with these LSI cards in NexentaStor?
