I would like to add some context to this inquiry.
I am looking at this from an NDMP backup / restore perspective. I backup a volume using NDMP specifying a dump type of 'SMTAPE'. This works as always. Now, to restore this backup, I am instructed to do the following:
1. Create a new DP volume on the filer.
2. Put this new volume in restricted state
3. Use the NDMP DMA user interface to select the destination volume for a NDMP SMTAPE restore. In my case the DMA expects to receive restricted volumes in the NDMP_CONFIG_GET_FSINFO reply messages. This was the behavior prior to 9.3. But this is not the only problem. On a clustered filer with the NDMP cluster extension enabled, location affinity information is needed by the DMA to perform a restore from a locally attached tape drive. The affinity information for all volumes in the filer is sent in the CONFIG_GET_FS_INFO reply message. Without this information the DMA cannot select an appropriate tape drive to use for this restore.
