backup failure

[Former Member]

I've configured my backup to run as shown in the script below ie

mt -f /dev/rmt/1 rewind

su - prdadm -c "stopsap R3"

su - oraprd -c "brarchive -i force -c force -v SCRATCH"

su - oraprd -c "brbackup -u / -c force -t offline -m all -p /oracle/PRD/102_64/dbs/initPRD.sap -v SCRATCH"

su - prdadm -c startsap

of late my backups have been failing with the error below appearing in the log ie

write: I/O error

This means that either the tape was not initialized properly or its damaged... change the tape and try again
