Attempts to update/add credentials to a NetBackup Media Server Deduplication (MSDP) media server fails "Invalid credentials for type PureDisk server"

Cause

Depending upon the spad session log error above, either the incorrect deduplication engine password was supplied or an invalid password was supplied.

The NetBackup Administration Console Media and Device Management | Credentials | Storage Servers | Change Storage Server | Properties uses DSM (Disk Service Manager) to communicate with the MSDP media server's RDSM (Remote Disk Service Manager) via NBRMMS (Remote Monitoring & Management Service) which in turn communicates with the NetBackup Deduplication Manager (spad) process. Hence the logs to focus on are DSM on the administration console system, RDSM/NBRMMS on the MSDP mediasvr and lastly MSDP mediasvr spad session logs.

 

Solution

If the spad session log reports 'No such user', consult the <dedup_path>\log\pdde-config.log on the MSDP media server, note the 'SPALOGIN =' line which contains the name of the media server deduplication engine account supplied when the MSDP  media server was initially installed/configured. This accountname must be supplied after the '-sts_user_id' argument in any 'tpconfig -update -storage_server' or tpconfig -add -storage_server' command.

If the spad session log reports 'invalid password' consult the administrator who initially installed/configured MSDP for the password. If this is not possible, contact Symantec Support for further assistance.
