Hi folks,
After enabling multipathing on Solaris server I encountered this issue with path to tape library unit.
When I attempt run an inventory on the robot I get the following errors.
Solved! Go to Solution.

Solaris Sparc or x86?
We have seen numerous problems (on this forum) on x86 servers where MPxIO was enabled.
Only way to get robotics working was to disable MPxIO.

Does robtest work, can you move a tape from a slot to a drive and back again?
If not, look outside of NetBackup.

Oh ok.... Yes it's an x86!
$ robtest

Is there any point to try to play around and see if I can get it working? Or is this a know bug that is not currently supported?
I have multipathing enabled SAN storage devices and would like to keep this functionality as throughput is greatly increased.

I suppose you could play around with it if you want, but:
Configuring Solaris 10 x86 for multiple drive paths

To use multiple paths to the same tape drive, NetBackup requires that Solaris Multiplexed I/O (MPxIO) be disabled.

Yea no joy... I attempted to create a single path to each drive and still have MPxIO enabled. There was an issue still with the robot. When I did disable MPxIO it worked and I could see both 2 drives and robot.
Could I use Veritas Volume manager to manage storage LUNs. This should not affect how Solaris OS or netbackup views the tape drive?

Since I have reconfigured drives and robot I am getting below error when running backups.
"The robotic Library is not defined in EMM"
Any ideas how I can resolve this?

I wanted to suggest Storage Foundation (Veritas Volume Manager) but obviously had no idea if something like SF Basic (free version) would be sufficient.
About your latest problem - were daemons restarted after reconfig?
Please restart NBU, then post output of 'tpconfig -l'.

Double-check STU specified in the staging portion of the DSU config. Just re-select the Storage Unit for this robot & drive combination.
