Backups failover to LAN even though Fibre Transport devices available
If a NetBackup FT media server has multiple network interfaces for VLANs, backups may failover to LAN transport if the NetBackup host name order is configured incorrectly.
See About Fibre Transport media servers and VLANs.
For all of the hosts that participate in the backups, examine their Additional Servers lists on their NetBackup Administration Console host properties Servers pages. Verify that the FT server's primary host name appears before any other interface names for that FT media server host in. If it does not, fix the incorrect host name order as described in the following table.
Table: How to fix an incorrect host name order in NetBackup
Task | Procedure |
|---|---|
Stop the FT services on the media server | |
Delete the FT server from the NetBackup EMM database | Use the following NetBackup command to delete the host from the NetBackup EMM database as an FT media server: nbftconfig -deleteserver -Me hostname The host remains in the EMM database as a NetBackup media server. |
Re-order the list on each host | If necessary, delete all of the network interface names of the FT media server from the list. Then, add the primary host name first and then the remainder of the host names in any order. The list appears in the host properties Servers page for that host. See the NetBackup Administrator's Guide, Volume I: |
Start the FT services on the media server | |
Scan for FT devices from each SAN client | When the FT media server is discovered during the rescan operation, NetBackup adds it to the EMM database as an FT media server. See Rescanning for Fibre Transport devices from a SAN client. |
