Creating Multiple IOA Clusters on a Single Switch
Figure 4-2
In the illustration, Site-SJC consolidates the tape backup from Site-RTP and Site-SAC. Each IOA cluster
represents a site pair, which means there are two unique clusters. This topology provides segregation and
scalability of the IOA service across multiple sites. In the Site-SJC, a single switch can participate in
multiple IOA clusters.
Figure 4-2
Before creating another cluster on sjc-sw2, create a third site SAC with the sac-sw2 switch. Clustering
Note
and IOA service must be enabled, and IOA interfaces must have been provisioned on the sac-sw2 switch.
To create another IOA cluster on sjc-sw2 with SAC, follow these steps:
Command
Step 1
sjc-sw2# config t
Step 2
sjc-sw2(config)# ioa cluster
tape_vault_site2
Step 3
sjc-sw2(config-ioa-cl)# node local
sjc-sw2(config-ioa-cl-node)#
interface ioa2/3
Step 4
sjc-sw2(config-ioa-cl)# node sac-sw2
sjc-sw2(config-ioa-cl-node)#
interface ioa2/3
