Hi,
I'm trying to restore some data from a filer but keep getting the below error. I have tried restoring various different folders to various locations and all fail with the same error. I have disabled/re-enabled the SCSI ports on the filer - ensured detection of tape drives by the filer, killed NDMPD and restarted it all to no avail. Any ideas on what is causing this error?

I have had a similar issue to this myself i believe. If i remember correctly it was due to the restore trying to use a drive that did not have a direct path to the NAS box. If the media server doing the restore has the NDMP drives in use it will try and use another drive in the same library, this will cause this problem.

run tpconfig -dnh and see if your media server is configured to connect to the filer you are trying to restore too, also check that you have a NDMP drive configured to this filer too, because you can have the access but without a drive configured.
hope this helps.

You may also want to confirm that the NDMP device s using a version of the NDMP protocol that is supported by your NetBackup version. Also that your authentication paramters are set correctly. See the below excerpts from NDMP.org:
NDMP_ILLEGAL_ARGS_ERR Protocol version suggested by the client is not
supported by the server. The client should retry
the request with a lower protocol version number.
NDMP_ILLEGAL_ARGS_ERR Specified authentication method not supported.

Thanks for everyone's reply. I've done a bit more investigation and turns out I am able to restore data if I choose individual files and kick off a restore job for each file individualy. It only fails with the NDMP_ILLEGAL_ARGS_ERR when I choose an entire folder (and all it's sub folders) to restore. Having said that I assume I can rule out an authentication or protocol issue.
Unfortunately my work-around won't cut it as you'd imagine it wouldn't be fun kicking off 2000 seperate restore jobs to recover someone's files. So I'm still searching for a solution to this.
thanks for all the help and advice thus far.

What kind of machine is your NDMP host? Have you examined the NDMP logs on that side? On a netapp filer, you'll need to increase the verbosity to get good ndmp logging.
