I got the following message during backup of one and only one node,
always the same, since few days :

ANR0523W Transaction failed for session 127 for node BCV51S80_SAP (TDP
R3 HP) - error on output storage device.

The meaning is that TSM stop a db transaction because of device problem
BUT there are no device problem of any kind and my backups felt down in
error.
On TSM server (AIX 5.3 and TSM 5.3.4.2), there are no filesystems
corruptions.

I suspect a possible db corruption but there are no other symptoms than
this one.

Some help ?
