The lower levels of the CAM SCSI driver allow the higher
levels to provide a pointer to space for a Request Sense
buffer in the data structure used to send commands. If
a particular command fails, the lower levels of the driver
will automatically do a Request Sense command to find out
what caused the error. In this case, it would appear that
the Request Sense failed. From the look of it, the device
isn't talking anymore.

It means your tape drive is misbehaving. You have some hard errors logged
as well. It looks like you got a hard error from the drive, and during the
attempted recovery, some operations failed.
Looks like unit 6 on your second SCSI bus (bus 1).
Since it's impossible to tell from the UERF output what type of drive you've
got plugged in, it's hard to be more specific. Tape drives are more messy
than disk drives, and to know exactly what a given SCSI sequence does, you
often need to know what kind of tape drive you're dealing with.

Hard to say. I have no particular experience with that particular model or
with the 3480 style drives in general. If there are cleaning cartridges for
it, I'd run a cleaning cartridge cycle, and if there are diagnostics for it
I'd want to run the vendor diagnostics (wishful thinking, I realize). Take
a look at the tapex reference page for the "out of the box" UNIX exerciser,
or look at what's in the VET package on the firmware CDROM. But either way
it is likely to be the drive acting up. I just don't have practical advice
based on experience with that drive model.

Here is the original message:
Does anyone know what a CAM SCSI error "AutoSense Failed" on a tape drive
can mean?
I have included the uerf logs. Any help at all would be appreciated.
Will Summarize.
