Unable to take backup and br logs gererated without exit code

Hi Master's

My client has HP-UX B.11.00 U 9000/800. Tape device path is 0/0/1/0.2.0 stape C1537A 12 GB DDS3 Data Compression Tape Drive (DAT)
When I have performed the backup thru SAM, It's shows following logs in different path and message as below.

Br_log entry logs generated without exit code.
Full backup started on hadmhp1 : Mon Sep 28 10:31:21 PDT 2009 (Scheduled Backup)
{ fbackup -0 -u -g /etc/sam/br/grapcyber -I /var/sam/log/br_index.full -c /etc/sam/br/fbackup_config -d /var/adm/fbackupfi
les/dates -f /dev/rmt/0mn } 2>&1

If I try to generate the index file from tape device

Getting list of files...
frecover(2105): did not find expected file marker
frecover(5409): unable to read volume header
frecover(5418): not an fbackup volume; unable to read volume header
frecover(2105): did not find expected file marker

frecover(5413): attempting to read backup following bad volume header
frecover(5426): read error while attempting to read index. Skipping….( Back to SAM )

If I go with recovery with SAM tool

Automated Backups In SAM
CORRUPT AUTOMATED BACKUP -- REMOVE IMMEDIATELY

Syslog entry
hadmhp1 vmunix: SCSI TAPE: dev = 0xcd002040 I/O error during close

I am taking almost 33 GB backup in compression mode on 12 GB DDS DAT. Is the reason for unable to read or recover the backup ?

Please guide to solve the problem.
Thanks in advance

Re: Unable to take backup and br logs gererated without exit code

Hi Prashant,

it seems that you try to use the non-rewinding device for fbackup: /dev/rmt/0mn
This is not possible; try changing it to /dev/rmt/0m

it would be nice if you always got a second chance

John,
Thanks for the reply. Can you tell me how i change the /dev/rmt/0mn to /dev/rmt/0m
reboot is require or any changes will happened, bcoz it's production server.

Please guide.

Re: Unable to take backup and br logs gererated without exit code

Hi again Prashant,

judging from the log: "Scheduled Backup", I assume that your backup is scheduled in SAM; try SAM-->Backup and Recovery --> Scheduled backups...
There must be a an existing backup and you need to change the device used.
