Explanation: A master server process that tried to initiate communications with the media host timed out (can be either the master or a media server). This problem can occur during a backup or restore in either a single or a multiple server configuration.
Recommended Action: Determine which activity encountered the connection timeout failure by examining the All Log Entries report for the appropriate time period. If there are media servers, determine if the timeout occurred between the master and a media server or if only the master was involved.
Verify that the schedule specifies the correct storage unit.
Run the ping command from one host to another by using the following combinations:
From the master server, ping the master and all media servers by using the host names that are found in the storage unit configuration.
From each of the media servers, ping the master server by using the host name that is specified in the NetBackup server list. On a UNIX or Linux server, the master is the first SERVER entry in the bp.conf file. On a Windows server, the master is designated on the tab in the Master Server Properties dialog box.
To access this dialog, see "Using the Host Properties window" in the Troubleshooting Guide.
Verify that the master server can communicate with bpcd on the host that has the storage unit.
See "Testing media servers and clients" and "Resolving network communication problems" in the Troubleshooting Guide.
If necessary, create debug log directories for the following processes and retry the operation. Then, check the resulting debug logs on the master server:
If the error occurred during a backup operation, increase the logging level for the diagnostic and debug logs for nbpem, nbjm, and nbrb (use the vxlogcfg command).
See "Configuring and using unified logging" in the Troubleshooting Guide).
If the error occurs during a restore operation, check the bprd debug logs.
