Managing deduplication servers
After you remove the load balancing server, restart the NetBackup Enterprise Media Manager service. The NetBackup disk polling service may try to use the removed server to query for disk status. Because the server is no longer a load balancing server, it cannot query the disk storage. Consequently, NetBackup may mark the disk volume as DOWN. When the EMM service restarts, it chooses a different deduplication server to monitor the disk storage.
If the host failed and is unavailable, you can use the tpconfig device configuration utility in menu mode to delete the server. However, you must run the tpconfig utility on a UNIX or Linux NetBackup server.
For procedures, see the NetBackup Administrator’s Guide for UNIX and Linux, Volume II.
