Ken, There are some issues in the way current the TSM servers handles the NDMP backups but in my opinion, they are making great progress with the upcoming TSM server V6.1 release.
The "Error beginning NDMP backup - illegal arguements.Check that the filespace/path '/vol/xyz/-' exists." error indicates that the path specified in the virtual filespace mapping definition of the volume you are trying to backup is either incorrect or wasn't available when you issued the BACKUP NODE command (If you are running scheduled snapshots) In our storage environment (TSM V5.5.2.0 + NetApp N series filers), we make use of NDMP to backup the snapshots for numerous volumes, cifs shares on the filers. Here is a rough draft of complete NDMP implementation. * After creating a NDMP user on NetApp filer, generate a password then enable NDMP on the filer * Define disk storage pool for the Table Of Content, define a domain, policy set, management classes having the newly created TOC storage pool for destination. * Define a node with type=nas on the TSM server using the NDMP user and password generated by the filer, define the datamover and virtual filespace mapping * Define a serial script (backup node Node_name /Virtualfsmap mg=$management_class mode=$type_of_backup wait=yes) and define a command schedule to run the script after the snapshot is created otherwise you will receive the current ANR9999D error message.

These volumes have qtrees defined for the larger top-level directories. There are numerous other small top-level directories that are not in qtrees. We are running TSM 5.5.2.0 and using the Filer->TSM->Library method of NDMP backup (storing the backups in TSM native storage pools). It is not practical to backup the entire volume in one shot, but backing up the individual qtrees via BACKUP NODE is manageable. The problem that I have is how to specify backing up the non-qtree portion of the volume. The NetApp commands use a trailing dash after the volume name to indicate non-qtree data (ie: /vol/xyz/- ) however BACKUP NODE complains of an invalid parameter when I use that convention. I tried setting up a virtualfsmapping with the trailing dash and it is accepted for the mapping, however the subsequent BACKUP NODE process fails after it starts with an ANR9999D catchall: "Error beginning NDMP backup - illegal arguements.Check that the filespace/path '/vol/xyz/-' exists." Anybody backing up these filers at the qtree level? How do you handle the non-qtree data? We're new to the whole NDMP world - seems a few steps back from what TSM can do natively.
