Thanks for that, I did have a look but the folder is there, where as the document states that it isn't there. I did remove the line anyway but that brought back a 282 exit code and down the vault service!
The NetBackup Vault Manager service is down, possibly because of the following: the Vault is not licensed, the vault.xml configuration file is corrupt, or the vault.xml configuration file upgrade failed during an upgrade installation.
Looking closely at the T/N that Bill quoted & also another similar one ( http://seer.entsupport.symantec.com/docs/283390.htm :(
For each of the Vault sessions that exist in the vlteject.mstr file there must be a corresponding SID folder in the /usr/openv/netbackup/vault/sessions directory. If the directory does not exist then a Status 12 or garbage text will appear.
In order to stop these errors from occurring it will be necessary to manually edit the vlteject.mstr file ... Any line for a session ID that does not have a matching session directory will need to be removed.
Notice "...for each..." and "...Any line..." - so should not just be looking at the sid that is being reported on but ALL sids?
