Thus far, a number of months now, my server administrator has not been
able to get our large database (DB2/6000; or large filesystem) backups
to work.


The backup job I ran for the sniffer trace test - that according to the
ADSM log didn't have any problem - failed with the same error message as
virtually every time before:

Tue Nov  5 20:00:03 PST 1996
starlight> db2 BACKUP DATABASE u990 USER u990db using   use ADSM open 2
sessions with 2 buffers without prompting
SQL2025N  An I/O error "-50" occurred on media "ADSM".

Also the backup of the filesystem on starbright that I was performing
Tuesday also failed after many hours of backup effort:
