Moving a Node From One ServerNet Cluster to
Another
If you have more than one ServerNet cluster, you might want to move a node from one
cluster to another. Note the following considerations before moving a node from one
cluster to another:
•
You must ensure that software on the node being moved is compatible with the
software on the cluster being joined. For software compatibility issues, see
Section 2, Planning for Installation and Section 4, Upgrading a ServerNet Cluster.
•
In order to move a node from one cluster to another, you must have access to an
unused port on the receiving cluster. If no unused ports are available, refer to
Section 4, Upgrading a ServerNet Cluster, for more information about merging
clusters.
As an example, the following procedure moves a node from cluster A to cluster B:
1. To remove a node from cluster A, complete the procedure for Removing a Node
From a ServerNet Cluster on page 6-2.
2. To add the node to cluster B, complete the procedure for Adding a Node to a
ServerNet Cluster on page 6-1. Adding the node includes:
•
Connecting the cables from the recently removed node to the X-fabric and Y-
fabric cluster switches for cluster B
•
Configuring new Expand-over-ServerNet line-handler processes between the
node you are adding to cluster B and the other nodes in cluster B
Even if you deleted the line-handler processes on cluster A, you can quickly reconnect
the node to cluster A by repeating the preceding steps and using the automatic line-
handler configuration feature of the guided procedure.
