Explanation: A process on the master server cannot connect to a particular host on the network when it tries to initiate communication with the media host. This problem can occur during a backup or restore in either a single or a multiple server configuration.
Recommended Action: Determine which activity encountered this failure by examining the All Log Entries report for the appropriate time frame. If there is more than one NetBackup server (one or more media servers), determine the following: if the failure was between the master and a media server or if only the master server was involved. 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 in the storage unit configuration.
From each of the media servers, ping the master server host 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.
To access this dialog, see "Using the Host Properties Window" in the Troubleshooting Guide.
See "Testing Media Servers and Clients" and "Resolving Network Communication Problems" in the Troubleshooting Guide.
If necessary, create debug log directories for bprd and retry the operation. Then, check the resulting debug logs on the master server. If the error occurred during a restore, check the bprd debug logs.
