Backup Problem
Scenario will be, full backup not working or control backup not working.
Few helpful tips:
- Check if the media is faulty is faulty or there is lock in the media.
- Check to see if the tape device is detected by the system. If not try to restart to detect it. Some time you need to reinstall the driver.
- #ls –l /dev/st0 ( to check the drive)
- tar ztvf /dev/st0 ( with the media inside the tape, if nothing shows then tape could be bad )
If driver problem (#lsmod >># rmmod aci…. >># insmod ac….. )
- Run the backup script in test mode with tape inside the tape device but in test mode. (# /u/cc/binl/baksys –t)
Few cool commands
#mt –f /dev/st0 staus
#mt –f /dev/st0 erase
Normal backup error message
Tar:/dev/st0: cannot read: Input / output error
