If the drain fails, check the following:
- Turn off netbackup: /etc/init.d/netbackup stop
- Remove the sg driver from the modules by executing:
- modinfo | grep sg
Note the module number.
- modunload ${mod_number}
- Remove the scsi tape driver from the modules by executing:
- modinfo | grep st
Note the module number.
- modunload ${mod_number}
- If drain is still failing, execute drshow unsafe and troubleshoot any remaining unsafe drivers
- complete_detach ${board}
- reconfig
