Hello everyone,
I got no answers but figured it out by myself with the help of HP tape
specialists..
It turns out that all external/internal tape drives not used within a
library should have the OEM1 firmware. It's the same firmware for all
tapes but of course you should preferably get a patch from your vendor
(SUN, in this case). Also, in case you didn't know, every DLT drive has a
very intersting hardware log that you can access with the right tools. It
shows things like SCSI errors reported by the drive, keeps a log of tape
errors and warnings (such as a failure to clean the drive when it requests
to). The only way I was able to see that log was through the use of HP's
Tape Tools (LTT) which ran under Windows NT/2k..

Subject: DLT8000 and tape firmware...
Hello everyone,
Not asking for an official answer, of course, since this is more on the
"hacking" side but Just wondering if anyone had the same dilemma..
I have an early internal DLT8000 tape drive made by HP (it's a re-packaged
QUANTUM DLT8000 drive) that I'm using on a Sun Blade 2000 box. I got a
Flexipack to put the drive in and I would like to update the drive's
firmware to correct some problems. The issue that I'm pondering is: Do I use
the Sun dlt8k Firmware or do I use the HP-provided dlt8k firmware?
AFAIK, the Sun DLT8000 and the HP DLT8000 are the same hardware (They're
Quantum DLT8000 drives). Moreover, the firmware patches from both HP and SUN
look very similar:
HP (from the support site):
-rwxr--r-- 1 u1 users 1188928 Sep 18 11:11 ltt_dlt8000_v080_oem1.frm
Sun (from SUN patch 112067-01):
-rw-r--r-- root/other 1187840 2001-09-19 22:32 112067-01/D8OEM1.V80
They're different sizes but both of them say "V80" and "OEM1"...
I'm tempted to use the Sun FirmWare ever since I figured that Drives with
Sun firmwares are usually more compatible with Sun boxes and quicker than
generic drives (one HP DDS4 drive made by SUN and another of the same make
but bought from HP did not provide the same ufsdump throughput , even with
adapted jumper settings.. or perhaps that's just me..).
Any ideas/comments/etc??
