Support for multiple domains across networks for Veritas Data Deduplication
You can use a single deduplication pool to backup data from multiple NetBackup domains. The Veritas Data Deduplication server deduplicates backups originating from different subnets. Use the network ip addr show command to list the multiple subnets that have been created.
Network> ip addr show IP Netmask/Prefix Device Node Type Status -- -------------- ------ ---- ---- ------ 192.168.10.5 255.255.255.0 eth5 vaupg_01 Physical 192.168.10.13 255.255.255.0 eth5 vaupg_02 Physical 192.168.30.2 255.255.255.0 eth4 vaupg_01 Physical 192.168.30.10 255.255.255.0 eth4 vaupg_02 Physical 10.209.192.206 255.255.252.0 eth1 vaupg_01 Physical 10.209.192.208 255.255.252.0 eth1 vaupg_02 Physical 10.209.194.38 255.255.252.0 eth1 vaupg_01 Virtual ONLINE (Con IP) 192.168.10.22 255.255.255.0 eth5 vaupg_01 Virtual ONLINE 192.168.10.25 255.255.255.0 eth5 vaupg_02 Virtual ONLINE 192.168.30.15 255.255.255.0 eth4 vaupg_02 Virtual ONLINE 192.168.30.20 255.255.255.0 eth4 vaupg_01 Virtual ONLINE
You can use the following command to configure the deduplication server with a virtual IP.
Dedupe> config filesystem1[,filesystem2,...] IP username [catfs_name] vdd_version [encryption] [worm=yes] [minret] [maxret] [node_name] [config_name]
For example:
Dedupe> config D3_3533793 192.168.10.22 dedupeuser CAT_3088152 19.0.1 enable_encryption=no enable_worm=yes 3600s 1892160000s cluster1_01 msdp-worm Access Appliance dedupe INFO V-493-10-3732 Deduplication server configured successfully
You can verify that the IP has been added successfully using the dedupe show command.

You can add another IP from a different subnet.
Dedupe> addip <IPaddress>
For example:
Dedupe> addip 192.168.10.25 ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the deduplication server. Dedupe> addip 192.168.30.15 ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the deduplication server.
Dedupe> addip 192.168.30.20 ACCESS dedupe INFO V-493-10-0 IP has been successfully added to the deduplication server.
You can verify that the virtual IP is added successfully. The dedupe show command is used to display information about the deduplication server that has been configured. The output of this command includes the file system(s) being used, deduplication server status, storage capacity, secondary IPs used, percentage of memory usage, maximum cache size, and the IP and the cluster node on which the server is running.

Use the network ip addr show command to list the multiple subnets that have been created.
Network> ip addr show IP Netmask/Prefix Device Node Type Status -- -------------- ------ ---- ---- ------ 192.168.10.5 255.255.255.0 eth5 vaupg_01 Physical 192.168.10.13 255.255.255.0 eth5 vaupg_02 Physical 192.168.30.2 255.255.255.0 eth4 vaupg_01 Physical 192.168.30.10 255.255.255.0 eth4 vaupg_02 Physical 10.209.192.206 255.255.252.0 eth1 vaupg_01 Physical 10.209.192.208 255.255.252.0 eth1 vaupg_02 Physical 10.209.194.38 255.255.252.0 eth1 vaupg_01 Virtual ONLINE (Con IP) 192.168.10.22 255.255.255.0 eth5 vaupg_01 Virtual ONLINE (Dedupe IP) 192.168.10.25 255.255.255.0 eth5 vaupg_01 Virtual ONLINE (Dedupe IP) 192.168.30.15 255.255.255.0 eth4 vaupg_01 Virtual ONLINE (Dedupe IP) 192.168.30.20 255.255.255.0 eth4 vaupg_01 Virtual ONLINE (Dedupe IP)
You can also add a second user. The second user is used to add the second NetBackup domain, if required. You should use a different user for every new NetBackup domain.
Dedupe> adduser user1 Enter Password: Confirm Password: ACCESS dedupe INFO V-493-10-0 Adding new user user2 to deduplication server. ACCESS dedupe INFO V-493-10-0 Added new user user2 to deduplication server successfully.
You can perform backup and restore operations from the NetBackup domains from the two subnets.
Note:
You can remove the virtual IP that you added later after the initial configuration. But you cannot remove the virtual IP specified during the initial configuration.
Dedupe> removeip IPaddress
For example:
Dedupe> removeip 192.168.30.15 ACCESS dedupe INFO V-493-10-0 IP has been successfully removed from the deduplication server.
You can verify that the second virtual IP has been removed from the configuration using the dedupe show command.

You can use the dedupe unconfig command to free up all the virtual IPs added to the deduplication server. This command also unconfigures Veritas Data Deduplication from the cluster.
Dedupe> unconfig destroy_fs=yes config_name ACCESS dedupe INFO V-493-10-0 Removing deduplication server configuration... ACCESS dedupe INFO V-493-10-0 Deduplication server unconfigured successfully.
