Can you tell me if a windows media agent (v9) supports multi-path software, such as EMC Powerpath.
Currently we have a windows MA, which has HBA's to the SAN where the Mag Libs are defined. There is no multi-path software installed (previously v7 MA when installed it didn't support powerpath apparently) so within windows disk management there are multiple disks for the same location. I.e. there are 4 paths to that location, so 4 disks are displayed.
Some are disabled, some unallocated and the other assigned as a drive mount (maglib).
How do you decide which one to disable, leave unallocated or assign as a drive? I've had a look for some documentation but can't find anything. I think its to do with the bus locations, but not sure?
If multipathing software, EMC Powerpath, was installed then only 1 device would be shown.
This could be setup this way as it was previously a v7 MA, but i'd like to add an additional mount path to the maglib but not sure which to allocate and disable.
Any advice would be great
