Even if you aren't multipathing your local disk, it should have a scsi id.
try manually running

# /sbin/scsi_id -v -g u -s /block/sda

If this fails, hopefully you'll get some debugging information. If this works
correctly, then try running

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.

Thanks


# /sbin/multipath -v6

and check if you can see this error there. If so, hopefully you'll get some
useful debugging information. Otherwise, you can start multipathd with
debugging

# /sbin/multipathd -v6

And parse through all the stuff you get to see there is any debugging
information there.
