We use our DataDomain systems as NFS based file devices. It works very well as long as you keep in mind it's NFS you are dealing with.
If your TSM server is on AIX, we found that these mount options help a LOT : combehind,biods=128,numclust=1024. AIX has some issues with high sequential NFS workload, and these help a lot. We use to get timeouts to DD based file vols fairly frequently and these options stopped that. If you are running as non-root, then you need to set owner:group of the mount point and files/dirs under it to the TSM owner:group. Also, to access a DD from AIX you need to issue cmd: nfso -p -o nfs_use_reserved_ports=1 Here is our /etc/filesystems entry for a DD mount point: /DD/tsmx: dev = "/data/col1/tsmx" (=> that's a mtree that the DD replicates to a DR site) vfs = nfs nodename = isddxxxx mount = true options = bg,hard,intr,sec=sys,rsize=65536,wsize=65536,proto=tcp,timeo=600,retrans=2,combehind,biods=128,numclust=1024 account = false and from the mount cmd isddxxxx /data/col1/tsmx /DD/tsmx nfs3 Mar 05 12:50 bg,hard,intr,sec=sys,rsize=65536,wsize=65536,proto=tcp,timeo=600,retrans=2,combehind,biods=128,numclust=1024,rw Your devclass points to the AIX mount point. Above it is /DD/tsmx. Actually, we put a subdir for the stgpool as in /DD/tsmx/<stgpoolname>. We also write the db backups recovery plan to a subdir /DD/tsmx/recovery, and have a script to copy the devconfig, scripts, crontabs, and other stuff into /DD/tsmx/config.

For example I can mount the NFS on my TSM AIX server 172.21.9.32:/data/col1/TSM2DB 215820.41 77422.70 65% 6 1% /TSM2DB and then use the "/TSM2DB" as the directory and it works. Bu when I try to use "172.21.9.32:/data/col1/TSM2DB" as the directory it is not accepted. What is the proper syntax ? I know I can do it with CIFS shares.
