Robot is missing and Drive is down
Good day to all,
My company is the vendor of Netbackup and I am the support for our one client.
Whenever they report to me, that Netbackup is not running, I always troubleshoot it and able to up the Netbackup by these commands.
I always found out that TLD (0) is not enabled, and my corrective action is resetting the button PHYSICALLY in the tape library. After that procedure TLD (0) is now enabled and the Robot is now accesible.
Next Step is bringing the drive to UP state through this commands
# /usr/openv/volmgr/bin/tpconfig –d
# /usr/openv/volmgr/bin/vmoprcmd -up n
where n is the drive number
I would like to know what is the root cause of this. Is it possible that Robot becomes missing instantly and the drive is going down without doing anything? What are the factors that cause the robot and drive to behave this way?
Thank you for reading and may you help me with my problem. Thanks and Regards -e_win
