Alert- problem with STK 9840B tape drives
We ran accross a problem with STK 9840B (FICON attached only) drives where
DB2 recover did not work from Image Copies. The Message we received from
recover:
DSNU1407I DSNUCBRT - MISMATCH BETWEEN THE NUMBER OF PAGES READ=273 AND
THE NUMBER OF PAGES ORIGINALLY COPIED=270

The message from DSN1COPY:
DSN1984I UNEXPECTED PAGE NUMBER, EXPECTING: 004E22

This was particularly nasty because it worked sometimes. I Genered an IC
from the tape to disk. Ran the same job to a different dsn on disk.
They did not compare correctly. STK has a fix for this problem----Install
MicroCode Level 1.34.352. I did not see this problem in the archives and
IBM DB2 support was not aware of this (they know about it now).
