Question : SCSI Tape Error 80000

I am running an LTO-4 SAS tape drive on an LSI controller and occasionally I get the following error in dmesg:

Mptbase ioctl:Loginfo (0x31120403) Originator (PL} Code={Abort} SubCode=(0x403)
st0: Error 80000 (sugg bt 0x0 driver bt 0x0 host bt 0x8)

I have been trying to figure out what error 80000 is and whether it is something I need to be concerned about. Does anyone know what error 80000 is and if it is indicative of a hardware or configuration issue?

Answer : SCSI Tape Error 80000

Looking a little more deeply into this, it's a message being generated by the mptbase module (I found the fprintf string in mptbase.ko.. though the message itself is a bit of a giveaway as to its location).

The only value of 80000 I can find in the fusion header files

   http://enpc3240.eas.asu.edu/lxr/linux/http/source/drivers/message/fusion/mptbase.h?v=2.6.17.10

is for MPT_NVRAM_TAG_QUEUE_ENABLE (line 919). So it may be that the adapter is attempting to enable tag queueing and failing. But to be sure, it would be best to contact LSI

for its precise meaning.
