Re: Tape / Backup Problem -- MIDRANGE-L



A few thoughts:
     1)  Clean the drive.  Do this at least once a week.
     2)  Try a brand new tape.
     3)  Vary off the drive and back on.
     4)  Get the Cumulative on ASAP.  You may also want to see if there are any
PTFs for the drive that did not make it onto
           the cumulative.

Just my 4 cents.

First of all.....thanks sooo much ya'll.  All the advice from yesterday really
paid off.  We successfully completed a nightly backup, excluding one web file
and saved it while active at a later time through a job scheduled entry.  I
print off half the letters that go through this list for "future reference".
Thank you thank you!

Now that you are buttered up (hopefully)...

I have gone to our "next step support" and IBM both with this problem for weeks
now, to no avail....

I have a tape drive that sports the following description on it:  QIC - 2GB
(DC).  We are using tapes that have the following label:  Sony QD9250, QIC-ER
2.5GB, QIC 2GB Standard cartridge 365.8mm/1200ft.  We are initializing the tape
as *QIC2DC because *QIC2GB doesn't seem to want to cooperate.

We have no problem getting nightly backups to work with these tapes on this tape
drive with this initialized density.  However, when we go to do a complete
system save, we get the following error message about 3/4 of the way through the
process:

 Media error on volume BACKUP on device TAP01.
 Save and restore file on media is not complete.
 *Attention* Media error detected by tape device TAP01.
 *Attention* Media error detected by tape device TAP01.
 *Attention* Media error detected by tape device TAP01.

Later, we tried doing the go save 21 again and got the following error message.
The system locked up and stayed that way for 24 hrs until we IPLed it.

 ENDSBS SBS(*ALL) command being processed.
 *Attention* Interface error: Tape unit TAP01 (resource TAP01) or IOP CMB01.

The system is a RISC box at V4R1.  Any ideas beyond loading the latest CUM PTF
CD?  (it's on order).

Thanks again!
