"Drive Managed by Remote Host" After Virtualization

Level 2

I have a Linux NBU master/media server that was happily using an IBM TS3200 Tape Library connected via FC until it (the server) began to experience hardware failures. To prolong its life, I virtualized the server, and it is now running as a Guest on an VMWare ESXI 6.5 host.

I removed the previous configuration of the library/drives, rezoned the Tape Library on our SAN to connect with the ESXI host, and configured SCSI passthrough for the guest VM. Here's the output of '/usr/openv/volmgr/bin/scan'

To my eye, everything looks correct.

When running the Storage Device Configuration Wizard, Netbackup can successfully detect the tape robot, but I am unable to add the Tape Drives to the configuration, as they are "Managed by a Remote Host".

I have seen a few topics with similar issues that recommended restarting the Tape Library. I have attempted this, as well as rebooting the Guest VM, without any effect.

Has anyone come across this issue before, or have any ideas on how to get the Drives recognized by the Wizard?
