I know this is a little 'non-NetApp' related, but please bear with me.
I am in the process of trying to troubleshoot a Veritas NDMP backup problem on a filer. I have been asked to try using the dump command on the filer to see if I can backup successfully, thus taking NetBackup out of the picture. I would appear to have an NDMP three-way config, is using the dump command to check this config valid?
