Hi all,



I encountered an error on the tape while doing a TDP for Exchange backup.

The error was "ANR 8355E I/O error reading label for volume A000122".



After the unsuccessful backup finished, some of the tapes that were mount
during the backup has changed from "readwrite" to "unavailable".

I have update all the unavailable tape to read write status and run the back
up but still I encountered the ANR8355E error and the tapes again change the
status to unavailable.



This issue happened last 3 days, when I received an intermittent
unsuccessful backup of TDP for Exchange due to error "ANS1315E (RC15)
Unexpected Retry request". It has brought me to check the volume for the
storage pool and found that some of tapes were in "unavailable and read
only" status. After I updated the status and ran again the backup the above
issue occurred.



Version of :

TSM 5.2.9 on AIX version 5.2

Client on Windows Server 2003 Ent Edition SP2

Storage Agent  5.2.9

TSM for Mail    5.2.1.0

TSM API         5.2.5

Tape library     IBM ULT3580-TD2 SCSI Sequential device with driver version
6.0.4.2





The issue above is only happen on one client. Others client backup work
successfully.



Appreciate your help.





Thanks,



Regards,



Zareyna Salim
