Adding a VIOS logical partition to a cluster

You can add a VIOS logical partition to a cluster by using the VIOS command-line interface.

1. Run the cluster command to add a VIOS logical partition to a cluster. The fully qualified network host name for the VIOS logical partition must be specified. For example,

   cluster	-addnode -clustername clusterA 	-hostname viosA2

   In this example, the viosA2 VIOS logical partition is added to the clusterA cluster.
2. To display the VIOS logical partitions in the cluster, use the cluster command. For example,

   cluster -status -clustername clusterA

3. Log in to the VIOS logical partition by using the padmin user ID to confirm the cluster characteristics as seen by the VIOS logical partition by entering the following commands:

   cluster -status -clustername clusterA
   lssp -clustername clusterA
   lssp -clustername clusterA -sp poolA -bd
   lspv -clustername clusterA -sp poolA

4. You can map the existing logical units to the virtual server adapters of the VIOS logical partitions. In this example, the logical units added to the viosA1 VIOS logical partition must be visible. However, these logical units are not yet mapped to the virtual server adapters that are provided by the viosA2 VIOS logical partition. To map existing logical units to the virtual server adapters of the viosA2 VIOS logical partition (while logged in to the viosA2 VIOS logical partition) and to list the mappings, enter the following commands:

   mkbdsp -clustername clusterA -sp poolA -bd luA1 -vadapter vhost0

   mkbdsp -clustername clusterA -sp poolA -bd luA2	-vadapter vhost1	

   lsmap -clustername clusterA -all

   The client systems can now be reconfigured to accommodate the new mappings.
