My client it’s using NDMP for FlexGroups backups by using Netbackup 10.0 . We want to take advantage of CAB so we configured the “SVM-scoped” for all the data SVM’s and using as “preferred-interface-role” for NDMP the one configured data type lif of the vserver so we use a dedicated lif for moving backup data traffic to de backup server.
In this case when we start a backup for the volumes that resides in the same node of the lif used for backups everything works fine. But when we migrate that lif to the partner node
to simulate a port failure the backup fails with the following message:
“ERROR: NDMP Vserver Connect: couldn't find any appropriate preferred local src IP address.
ERROR: NDMP Connect: Unable to Connect to [X.X.X.X]:3220 due to Network is unreachable.”
Is there any additional ndmp, lif or other configuration that I might be missing here? Volume affinity prioritizes any lif on the same node as the backed up volume?
As a recap. What we need (if possible) is to configure a dedicated data-type lif for backup-data traffic that give us the chance to keep backing up data even when it is migrated to the partner node.
Thank you all in advance!
