Physically Replacing a Cluster Node
At some time you may need to permanently replace one of the nodes in the cluster.
For example, over time you may slowly increase the number of applications running
on the cluster, which may require you to replace an existing node with a new, more
powerful and expandable cluster node.
To simplify integration of the new cluster node, Compaq recommends that you retain
the Microsoft operating system boot drives from the node being replaced for use in
the replacement node. If this is not possible, you need to perform the steps in the
“Installing a New Microsoft Operating System Boot Drive” section later in this
chapter.
Replacing a Cluster Node
To replace an existing cluster node:
1. Fail over to the remaining node all cluster groups that are running on the node
being replaced, if not already accomplished. During replacement of the node, all
cluster groups must be running on the remaining cluster node.
NOTE: Certain cluster-aware applications do not allow replacements of the node on
which the application was first installed. Remove these applications from the cluster
before replacing the first node the application was installed on.
2. Evict the node to be replaced from Microsoft Cluster Administrator.
3. Shut down and power off the node that is being replaced.
4. Remove the interconnect, LAN, Fibre Channel, and power cables. Remove any
other cables that are attached to the node. If the node is in a rack, remove it from
the rack.
5. For all hardware devices that will be used in the new node, remove them from the
node being replaced and place them in the new node. Install all other hardware
devices into the new node.
