Why we set robot path to one of the drive

[Bradman]

Why we set robot path to one of the drive in tape library and how we can check on which drive that path is set from master server cmd on AIX. And what will happen if that drive gets faulty and what we needs to do. Do we need to reset that path to other working drive meanwhile it gets replaced and do we need to configure the drive again or anything else we can do. Robot is under master server control on Aix. Looking for steps of command for Aix platform rather than gui interface.

I'm guessing you have an IBM 3584, or similar library. 

No way to check which drive the robot uses, unless you look on the library itself, or of course in the system documentation you keep updated. 

That said, the library will be one lun more than the drive, so if you display the paths to the drives at os level, you could match it up that way perhaps.

If the drives goes, yes, you lose the robot, you could reconfigure the robot to another drive, delete the robot in NBU, then re add via the wizard, and re run inventory.  Or perhaps set two control paths, and dual path the robot to NBU, never tried this myself, but believe it works.

Oh, the reason you set a control path as its called, is simply that that is the way IBM designed it, you 'present' the robot via a drive path.

Nothing unusual in that, HP robot here is exactly the same. You choose which of the drives you wish the robotics to run over, thats done only on the admin gui for the robot, nothing to do with netbackup.

And losing a drive does not necessarily mean you lose robotics, it rather depends what has failed.Jim
