Symptoms
Backup failing with the below error:
175297:save: Unable to set up the direct save with server 'NW_server_name':
Unable to connect to the storage node on host <storage_node_name>:
save failed to authenticate with nsrmmd on host <NW_server_name>: Timed out..Cause
nsrmmd stopped responding, and the server parallelism was set 32 (default); due to which no additional processes could be started for backups. The existing jobs were failing with timeout error.
Resolution
Stop NetWorker services to remove all the processes in hung state. Kill jobs manually if the process does not stop when services are stopped.
Linux:
Stop Services:
Confirm that all processes have stopped and collect the Process ID (PID) of any processes that do not stop:
Kill any hung services:
Start services:
nsr_shutdown
Confirm that all processes have stopped and collect the Process ID (PID) of any processes that do not stop:
ps -ef | grep nsr
Kill any hung services:
kill -9 PID
Start services:
service networker start
Windows:
Stop Services:
Confirm that all processes have stopped and collect the Process ID (PID) of any processes that do not stop:
Kill any hung services:
Start services:
net stop nsrexecd /y
Confirm that all processes have stopped and collect the Process ID (PID) of any processes that do not stop:
tasklist | findstr nsr
Kill any hung services:
taskkill /PID PID /F
Start services:
net start nsrd && net start gstd
Increase parallelism to a higher range and initiate the backup. Server --> Server Properties --> General
NOTE: View --> Diagnostic View must be enabled.
The server parallelism attribute controls how many save streams the server accepts simultaneously. The more save streams that the server can accept, the faster the devices and client disks run. Client disks can run at their performance limit or the limits of the connections between them. The default Server parallelism is 32; you can configure the parallelism up to 1024. When increasing values, it should follow: 32, 64, 128, 256, 512, 1024.
Server parallelism is not used to control the startup of backup jobs, but as a final limit of sessions accepted by a backup server. The server parallelism value should be as high as possible while not overloading the backup server itself.
