Adding SAN Volume Controller 2145-CF8 nodes to an existing cluster

You can add SAN Volume Controller 2145-CF8 nodes to your cluster.

This task requires that the following conditions are met:

The cluster SAN Volume Controller software version is 5.1.0 or later.
Note: SAN Volume Controller 2145-4F2 nodes are not supported on this version or later versions.
All nodes that are configured in the cluster are present.
All errors in the cluster error log are fixed.
All managed disks (MDisks) are online.

Note: You cannot combine SAN Volume Controller 2145-4F2 nodes and SAN Volume Controller 2145-CF8 nodes in the same cluster. The SAN Volume Controller 2145-4F2 node is supported only in SAN Volume Controller 4.3.1 and earlier releases.

Install the SAN Volume Controller 2145-CF8 nodes and the 2145 UPS-1U units in the rack.
Connect the SAN Volume Controller 2145-CF8 nodes to the LAN.
Connect the SAN Volume Controller 2145-CF8 nodes to the SAN fabric.
Power on the SAN Volume Controller 2145-CF8 nodes and the 2145 UPS-1U units.
Zone the SAN Volume Controller 2145-CF8 node ports in the existing SAN Volume Controller zone. The SAN Volume Controller zone exists in each fabric with only node ports.
Zone the SAN Volume Controller 2145-CF8 node ports in the existing SAN Volume Controller and storage zone. A storage zone contains all of the SAN Volume Controller 2145-CF8 node ports and controller ports that are in the fabric and used to access the physical disks.
For each system that is used with the SAN Volume Controller cluster, use the system management application to map the LUNs that are currently used by the cluster to all of the WWPNs of the SAN Volume Controller 2145-CF8 nodes that you want to add to the cluster. The SAN Volume Controller 2145-CF8 nodes must recognize the same LUNs that the existing nodes in the cluster can recognize before they can be added to the cluster. If the SAN Volume Controller 2145-8A4 nodes cannot recognize the same LUNs, the system is marked degraded.
Add the SAN Volume Controller 2145-CF8 nodes to the cluster.
Check the status of the systems and MDisks to ensure that status has not been marked degraded. If the status is degraded, there is a configuration problem that must be resolved before any further cluster configuration tasks can be performed. If the problem cannot be resolved, remove the newly added SAN Volume Controller 2145-CF8 nodes from the cluster and contact the IBM® Support Center for assistance.
