This is a Solaris 11.3 x86 SRU 22.214.171.124.0 Oracle server with 8GB Oracle Qlogic FC HBAs, connected to the SAN to access a new Disk Storage array:
A standard, self "assembled" Linux box (Supermicro based) with a ZFS/Zvol exported via a QLogic FC to the SAN (FC/SCSI Stack based on SCST (Generic SCSI Target Subsystem for Linux) with T10-ALUA).
We tested this new FC SAN storage device and tried to run sammkfs on it which reproducible triggers a kernel panic:
1) 1st panic at "Jun 15 10:17:14 " (almost identical panic stack as 4th panic at "Jun 15 11:16:47" , see below)

Customer have been playing around with different settings/blocksizes for the new Storage , specially with block and sector sizes, as they we want to benchmark these settings to settle down on a stable and fast set-up for the future.
