Hi,
With respect to the error
write failed: I/O error
There is defintely problem with your backup device. The device may be corrupt, so change and try the backup again...
With regards

Hi Sudhakaran,
My problem is solved. I actually cleaned the tape drive using the cleaning media, and the BRBACKUP started working perfectly.
Thanks & Regards,

Hi Senthil
For this Issue you have to set the following if the OS is AIX
Set the tape block size = 0 (variable value) with smitty devices -->tape device -> show/change characteristics of tape drive .
If in other OS please check whether the tape block size is mention as 0 and then fire the backup u will succeed...

Hi Ranjith,
Please us the following steps to resolve the backup issue.
chown -R ora<SID>:groupID /dev/st
chmod -R 777 /dev/st
su - ora<SID>
cd sapbackup
ls -lrth
find the brlow containts via grep command.
brbackup -i force -v SIDB01 c
Than run the command by increasing the value by one
brbackup -i force -v SIDB02 c
Now run the backup from brtools
Thanks and Regards,

Hi Sentil
Adjust the tape size specified via parameter "tape_size" in file "init<SID>.sap " to the actual physical value and then brarchive will request a tape change before cpio runs afoul of of the EOT.
Your backup fails because brarchive still thinks there's space left, but cpio terminates once it reaches the End Of Tape and at that time its to late for brarchive to intervene.
I think you should also re-calculate the compression rate for the tapes with brbackup -k only see http://help.sap.com/saphelp_nw70/helpdata/en/1f/db3226af7d3a45bae174fbd41054fe/frameset.htm

Hi,
Please check the tape size given in init<sid> file, correct it and then reinitialize the backup.
If with the above is not working, try to take backup with DD instead of CPIO.
mark the answer if useful.
Thanx/gopal
