Asynchronous
Sense
This feature is used on some HP-UX systems where the drivers “forget” if they are at a
filemark, and send
REQUEST SENSE
(without a preceding
CHECK CONDITION
) to find
out where they are. This feature should not affect systems that do not want
asynchronous sense.
3
The Mark bit may be set on asynchronous
REQUEST SENSE
.
7
The Mark bit will never be set on asynchronous
REQUEST SENSE
.
Attention after
Load
Some HP-UX (and possibly MPE) drivers expect
UNIT ATTENTION
sense after a tape is
loaded even though the host issued the load command.
3
U
NIT ATTENTION
and additional sense of 2800h (not ready to ready transition)
are posted for a command following a load, including those which just perform
rewinds, or do nothing.
7
U
NIT ATTENTION
is only posted when loading a new tape.
Caution on Hard
Error
3
If a hard error occurs on a read or write resulting in additional sense of 1100h
(unrecovered read error) or 0C00h (write error), the front panel will display a
Media Caution signal indicating that the drive requires cleaning.
7
No special front panel displays are used to report hard errors.
