Configuring the NetBackup client-side deduplication to support multiple interfaces of MSDP
If you have network configurations like VLAN or Subnet with NetBackup client, then the MSDP server has multiple network interfaces. These interfaces are connected to different switches or VLANs. As MSDP has only one storage server, NetBackup clients cannot access the MSDP server using the storage server name. The deduplication can fail on the clients.
You can add support for up to 30 interfaces.
Run the following steps to use the cacontrol command option (Location: /usr/openv/pdde/pdcr/bin/) to configure MSDP and specify the network interfaces that the NetBackup client can use:
- Log on the MSDP server.
- Use the following command to add the alternate interfaces:
cacontrol --interface add msdp-a.server.com
You can remove an added interface using the following command:
cacontrol --interface remove msdp-a.server.com
- Use either of the following options to validate the interface configuration:
cacontrol --interface list
bpstsinfo -si -storage_server msdp-a.server.com -stype PureDisk
Location of the bpstsinfo command: /usr/openv/netbackup/bin/admincmd/
- Configure the NetBackup client-side deduplication backup policy and run the backup operation.
