Adding SAN Volume Controller 2145-4F2 nodes to an existing cluster

You can add SAN Volume Controller 2145-4F2 nodes to increase the size of your cluster.

1. Install the SAN Volume Controller 2145-4F2 nodes and the uninterruptible power supply units in the rack.
2. Connect the SAN Volume Controller 2145-4F2 nodes to the LAN.
3. Connect the SAN Volume Controller 2145-4F2 nodes to the SAN fabric.
4. Power on the SAN Volume Controller 2145-4F2 nodes and the uninterruptible power supply units.
5. Zone the SAN Volume Controller 2145-4F2 node ports in the existing SAN Volume Controller zone. A SAN Volume Controller zone should exist in each fabric with only node ports.
6. Zone the SAN Volume Controller 2145-4F2 node ports in the existing SAN Volume Controller and storage zone. A storage zone should contain all of the SAN Volume Controller 2145-4F2 node ports and controller ports that are in the fabric and used to access the physical disks.
7. 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 2145-4F2 nodes that you want to add to the cluster. The SAN Volume Controller 2145-4F2 nodes must see the same LUNs that the existing nodes in the cluster can see before they can be added to the cluster. If the SAN Volume Controller 2145-4F2 nodes cannot see the same LUNs, the system is marked degraded.
8. Add the SAN Volume Controller 2145-4F2 nodes to the cluster.
9. 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 2145-4F2 nodes from the cluster and contact theIBM® Support Center for assistance.
