Scsi Persistent Reserve on Tape drive.

This is what i want to do:

SCSI Reserve/Release Setting
If you are using DDS with either of following operating systems, you need to disable the scsi reserve/release setting for DDS to function correctly:
• HP Tru64 UNIX
To disable the scsi reserve/release setting on HP Tru64 UNIX, use the scu command. For further information about using scu, refer to the scu man page.

This is what i got:

# scu -f /dev/ntape/tape0 preserve release
scu: 'persistent reserve out' failed on device 'SDLT320' at nexus [4/0/2]
scu: Sense Key = 0x5 = ILLEGAL REQUEST - Illegal request or CDB parameter,
Sense Code/Qualifier = (0x20, 0) = Invalid command operation code
# scu -f /dev/ntape/tape0 preserve reserve
scu: 'persistent reserve out' failed on device 'SDLT320' at nexus [4/0/2]
scu: Sense Key = 0x5 = ILLEGAL REQUEST - Illegal request or CDB parameter,
Sense Code/Qualifier = (0x20, 0) = Invalid command operation code

Now what; Ignore or Retry?

Re: Scsi Persistent Reserve on Tape drive.

Eric,
can you:
scu -f /dev/ntape/tape0
scu>show sense

Do any of the other options (clear/reserve etc.) work?

Re: Scsi Persistent Reserve on Tape drive.

Yes, this is still a problem. But the hardware that is needed to check the suggested sollution is no longer available to me. (Has been claimed to fix a production problem.) Until that is fixed i have no tape devices.....


Ill close this thread and will reopen one when it didnt fix my problem.
