I think maybe your library needs some service. I am pretty sure at this point,
that based on all the stuff you have described that it is a hardware issue with
the library....

funny thing happened...
I opened the library and closed it.  This caused a StorageTek audit.  Then
I went to TSM and ran audit library tekwolf checklabel=barcode.  I ran over
to the StorageTek and watched.  The Robot went to the bottom DRIVE and
scanned.  It then moved up a DRIVE and searched again.  It did this twice
more (I have 4 drives which were empty at the time).  At the end of this is
when I received the I/O error.  All the robot did was go to the 4 drives.
Shouldn't it have went to slot 210 and looked for the tape?

Any way -- I have to find a way to delete the slot 210 contents from the
storagetek memory.  Any ideas?

Unsuccessful(Document link: Marc D Levitan)





Hi George,
Is there a way to clear that ram and have the storage library re-audit the
library?  I am asking because my problem is that there is NO volume in slot
210.  (The Library thinks there is)  However, when I try an audit through
TSM, it errors out on slot 210.  I was able to checkout other volumes in
other slots because TSM associated a volume number to the slot.  In this
case though, TSM does not "see" any volumes in slot 210.

David, You made a comment that barcode problems would show up in an error
log...
not so. I have first hand experience here. I have lost my barcode reader
twice
in the last year from my 3575L32. Mine is configured as yours is;  2/14 and
as
one library. The first time the barcode reader stopped working, it was
actually
the card at the back of the library (RAM) where the element status info is
held.
The second time was the reader itself. Both times, the LED blinked and
appeared
to be functioning. Neither error was reported into the errpt. I only
noticed the
problem because of the audit library problem of not being able to go
through the
whole library reading labels before bombing. The problem with the card not
retaining the element info was very hard for the IBM hardware CE to
diagnose as
it doesn't show up using the normal diag or library diagnostic routines.
Marc's
problem won't be resolved for the tape in his slot 210. The library barcode
reader CAN'T read the barcode and the tape can't be mounted to read the
label.
Marc's error message indicates:

Illegal request - incompatible medium installed
   KEY 15                    SC 30   ASC 00

This means the tape format or medium itself is bad (this info from the SCSI
Bench Reference)

He needs to get the tape out of the library, check it back in, move data
and
then he could choose to audit the volume with the fix swtich invoked or
just
delete the volume and can it... Could another application have written to
the
tape? Could Marc have done dd to the tape? Both of these would mess up the
format or it could just be a bad tape.

I have your identical config except have TSM 3.7.4.0 server.  I also have
Atape
drive 5.3.9.0 - probably not most recent but fairly so.  If your much
behind
this, I would update it from IBM.  I have not had this specific problem,
but
have had some problems.  Several things to check.

1.  Run the audit and if you get an "Unable to read.." error then run it a
second time and see if it comes up.  The first time it is adjusting TSM to
match
library so second time should be no problem.  It there is I would suspect
TSM
problem, not library.  (Also when manuallly pulling /reinserting tapes it's
easy
to get them one slot off etc.  I have done it.  I always do an audit if I
have
been in library.

2.  You can do another check with tapeutil.  (The Atape drive usitily that
TSM
uses to talk to library).  Do theis command:
tapeutuil -f /dev/smc0 inventory > tapelist
Your /dev/smc0 may be different.  This can be run with TSM up AND drives
being
used.  You may get a "Busy" message, if so wait a minute and run again.  It
takes only about20-30 seconds.  Comapre the tapelist to TSM q libvol.
Tapelist
is in element order and shows if anything is robots, I/O station and
drives.  If
a tape is in drives it's home element is shown also.  This list is
"realtime" of
where tapes are in library.

3.  You could have a barcode reader problem but this would most likely show
up
in actlog or on Error log on LCD OP stations of 3575.   Do the tapes actual
labels look o.k.?

4.  How is library configured?  Is it just One Logical libray or more?  Do
you
just have the 2 top I/O ports or the additional 14?

I have ONe library and 2 i/o ports.

Some starting thoughts...

I have a 3575 L32 on AIX 4.3.3 and TSM 4.1.2. I had to manually inventory
mine using a printout from "select home_element, volume_name from
libvolumes
order by home_element". I removed any that were not on the list and checked
out the ones that were on the list but not in the library. Now the audit
library completes successfully, yet every time I get the "Unable to read
barcode..." message. I compare what is in the slot to what the system says
should be there (same), then pull the tape and re-insert it. Then the
library does its init element to rescan. I run audit db and a different
slot
will give the error. I have went through this cycle four times. Any request
for the tape in error work fine, though. Any suggestions?
