Brian,
If you use NDMP-compliant backup software, then you can connect the media changer as well as the tape drive directly to the NetApp filer.
I made experience with Budtool, and from a flexibility perspective it is imho better to connect the robotics to the filer since it eliminates to install robotics kernel driver on Unix hosts, i.e. spt driver for Solaris . One could quickly change and fail-over to another admin host while maintaining the robotics control . Only ndmp software is required while robotics driver might not exists for a particular Unix flavour. Klaus
Klaus,
Would you mind briefly explaining the process you used to connect the robotics to the filer? I was unable to determine the correct internal device name of the netapp's robotics controller when I tried this.

The robotics/library is a STK 9714 . I used the following jbmgr_config.hostname.1 file. One bus of the STK is connected to the Filer SCSI port and the other 2 drives on the STK scsi bus are connected to an SUN Ultra 2. One of my peer workers connected it appropriately and it works fine. I guess one want to work with STK to figure out the proper SCSI bus connections.
ROBOT_DEV_HOST your_filer_hostname ROBOT_DEV_NAME spt0 ROBOT_SCSI_ID 0 ROBOT_SCSI_BUS 0 DATA_DEV_NAME0 nrst0a DATA_DEV_HOST0 your_nac DATA_DEV_NAME1 /dev/rmt/1cbn DATA_DEV_HOST1 your_solaris_host DATA_DEV_NAME2 /dev/rmt/2cbn DATA_DEV_HOST2 your_solaris_host Of course the filer has "ndmpd on" active.
Hope this helps.
Warm regards from Munich Klaus
