MPxIO question

Greetings Forumers!!

I was given a T2000 with one, dual port, HBA card. The card had one fiber connection to the SAN and the former admin enabled MPxIO.

Yesterday, I learned that the other port was connected to the same SAN. This system is in another city so I don't have physical access to it.

My question is: Do I need to disable and enable MPxIO (with the re-config reboots in between) so that the device paths are in place?

Thanks In Advance!!

Enable MPXIO otherwise the system will see same HDD via 2 paths.
the disks will be shown twice in format command....
