Dear Sirs.
I did not count the postings I wrote to this group, it seems, in respect to the answers,
that really few people have DAT changers or a similar problem like me.
The problem I wish to describe is really serious to us and it hits two newer HP DDS4 tape
drive units, one single drive and one 6 cardridge changer unit.
What happens:
Since FreeBSD 4.6.2 (and exactly since then!) at the end of a DDS 4 tape I receive on
both machines at which the tape drive units are attached the same error from the kernel:
Mar 2 23:28:31 <kern.err> atmos last message repeated 14 times
Mar 2 23:28:33 <kern.crit> atmos /kernel: (sa0:sym0:0:5:0): WRITE FILEMARKS. CDB: 10 0 0 0 1 0

MTEOM command to clear this state.
Mar 2 23:28:33 <kern.crit> atmos /kernel: (sa0:sym0:0:5:0): tape is now frozen- use an OFFLINE, REWIND or
MTEOM command to clear this state.
(This is the error on ATMOS, a dual CPU system with a HP SureStore 40x6i, dmesg is attached).
On the other machine the error message is as follows:
Mar 1 22:25:43 <kern.crit> klima /kernel: (sa0:sym0:0:4:0): WRITE FILEMARKS. CDB: 10 0 0 0 1 0

Mar 1 22:25:44 <kern.crit> klima /kernel: (sa0:sym0:0:4:0): tape is now frozen- use an OFFLINE, REWIND or
MTEOM command to clear this state.
(This is the error on KLIMA, also a dual CPU system with a HP DAT40 single tape drive unit, dmesg attached)
On both machines, this error occured the same time and exactly at that point, when we moved from
FreeBSD 4.6 to 4.6.2-RELEASE. I think it's obvious that this could not be a drive damage.
I search google.groups for similar problems. I found several unanswered postings. I was said, that
this could be a hardware defect or a tape defect. I exclude hardware defect due to the mentioned fact above.
I changed 10 brand new original HP DDS4 tapes to another set of 10 brand new original HP tapes.
That did not change anything.
On both tape drives I did a 'mt erase' on a tape cardridge, but I received an error two times:
Apr 2 15:29:47 <kern.crit> atmos /kernel: sym0:5:control msgout: 80 6.
(on KLIMA it is the same message, two different tapes!).
For your information:
Bot tape units do have the standard DIP switch settings as for PC/PC-UNIX systems (standard
as mentioned in HPs documentation).
On the HP SureStore 40x6i changer, 'mt status' offers this status message:
root: /var/log: mt status

On the HP DAT40 single tape drive unit 'mt status' offers this:

'mt geteotmodel' offers:
root: /var/log: mt geteotmodel
/dev/nsa0: the model is 1 filemark at EOT
on both machines.
The software we use for backups is afbackup in its most recent release. I can read each file
backuped on the tapes execept those which ends up on one tape that has not been closed due to
the error mentioned above and to be continued on the second tape.
I think it seems not to be a afbackup software problem. afbackup worked perfect before
4.6.2 (we used 4.6-RELEASE before going on with 4.6.2).
I read an article in
http://bizforums.itrc.hp.com/cm/QuestionAnswer/1,,0xd6afba808b46d611abda0090277a778c,00.html
describing a similar problem and HP suggests a recalibration of the tape drive unit.
That sounds senseless to me.
Is someon out here with a little help?
How to ensure that the tape units are defective and not the tape driver of FreeBSD?
Any assistance would be appreciated.
Thanks a lot in advance,
Oliver
