I am looking to partition an Overland Neo2000 to be shared by a NetApp(825) and a backup server (ARCserve r11 w/ NDMP license). When you use the LPO (library partitioning option) in the Neo it loses the capability to run in sequential more - each partition can only be used in random access mode. Does anyone know how NDMP/NAS communicates with libraries/changers when directly attached? Do they need to be sequential changing devices are do they also support random access tape changers?
Thanks, Charlie
NDMP will support the random access mode (called a Medium Changer). If you run sysconfig -m you will see the medium changer on the NetApp. (sysconfig -t shows the tape drives).
How you use the Medium Changer depends on the backup software you use to
invoke the NDMP commands. I have tried NetBackup and Veritas via NDMP and both are straightforward in finding the NDMP Medium Changer thru the NetApp over the network.
