Failing over to an alternate server
Use the following procedure to enable automatic failover to an alternate server.
To enable automatic failover to an alternate server
- When automatic failover is necessary for a given server, NetBackup searches through the relevant FAILOVER_RESTORE_MEDIA_SERVERS list. NetBackup looks from left to right for the first server that is eligible to perform the restore.
Modify the NetBackup configuration on the master server are as follows:
By using the NetBackup Administration Console:
In the NetBackup Administration Console, in the left pane, expand NetBackup Management > Host Properties. Click on Master Servers to open the Master Server Properties dialog box. In the left pane, click on Restore Failover to open the Restore Failover host properties dialog box.
In the Restore Failover host properties dialog box, click on the Add button to open the Add Failover Servers window. Add entries for the media server and the failover restore server(s) and click the Add button in the Add Failover Servers window. Click OK.
By modifying the bp.conf file on a UNIX NetBackup server:
As root, add the following entry to the
/usr/openv/netbackup/bp.conf file:
FAILOVER_RESTORE_MEDIA_SERVERS = failed_host host1 host2 ... hostN
Where:
failed_host is the server that is not operational.
host1 ... hostN are the servers that provide failover capabilities.
There can be multiple FAILOVER_RESTORE_MEDIA_SERVERS entries and each entry can have multiple servers. However, a NetBackup server can be a failed_host in only one entry.
- Stop and restart the NetBackup Request daemon on the master server.
