You're out of luck here. Usually removing the driver (rmmod mpt_sas) is
the best you can do, it almost always force a complete scsi bus reset
and rescan, but that obviously won't do anything more than a reboot. Of
course you could try to force the drive offline, then online with
MegaCli:
MegaCli -PDOffline -PhysDrv [E:S] -aN
MegaCli -PDOnline -PhysDrv [E:S] -aN
Or you could try a controller scan:
MegaCli -CfgForeign -Scan -aALL
You're obviously either got an LSI firmware bug or a drive
firmware bug. The fact that several reboots and therefore controller
firmware restarts occured makes me thing that's the drive. WD SATA
drives are notoriously complete sh*te in professional environment and
love living their life by themselves, out of RAID arrays.
