I ran this command and received a sg_io failed status 0x8 0x0 0x0 0x2
message.  I think this is because my system is setup for Integrated
Mirroring (IM) and the OS sees the scsi controller instead of the scsi
device.  The output of the scsi_id command gives me the vendor
"LSILOGIC".  I tried this command on another system with the IM turned
off and it worked fine.  I'm not sure how to continue from here…I read
a post on a debian bug list that describes using the –p flag for the
command mpt-status to specify the scsi id of 0 or 1.[1]  Is there a
way to specify an id to scsi_id and if there is, how would that get
passed to the command on boot-up.
