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. -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac@xxxxxxxxxxxxxx> | +33 1 78 94 84 02 ------------------------------------------------------------------------ -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
