Configure tape library with 2-port drives

Level 6

Hi dear all,

I recently zoned a tape library with linux master server. when I am trying to add robot and browse device file there are 2 path for robot. if I select one of them, all drives will add to netbackup with 2 path, is it normal behaviour? need to install any multipating software? 

PS, each drive has 2 port and I zoned both of them to master server. also one drive selected as control path via library console.

If you have multiple paths to the tape drives, then yes this is normal behaviour.

NetBackup will only see the appropriate number of drives, and does not support a multi-path driver for tape. It is possible though to support a "failover" path to a drive - if one path goes down, you can reactivate the drive using the other path. 

This is not a seamless operation, and any in progress tape operations will fail.
