Chapter 10Preparing to Replace Hardware in a Cluster
For information about what to consider before replacing
hardware in a cluster, see the following sections.
Guidelines for Replacing Hardware
Follow these guidelines when replacing hardware on your cluster:
Before replacing hardware on the master node, perform a switchover
and then replace the hardware on the vice-master node.
Replace hardware of one type with hardware of the same type,
for the following reasons:
The vice-master node and master node must have the same hardware
and software configuration.
If several nodes are running the same applications, the nodes
might require the same hardware.
To replace hardware of one type with hardware of another type, you must
reinstall the node with a configuration adapted to the new hardware type.
Perform a procedure for each item of hardware that you change:
If you change one item of hardware, perform the procedure
for that type of hardware. For example, if you replace a disk perform only
the procedure to change the disk.
If you change a board that contains Ethernet cards, perform
the procedure to change the board and the procedure to
change the Ethernet card.
If you change a board that contains Ethernet cards and a disk,
perform the procedure to change the board, the procedure to change the Ethernet
cards, and the procedure to change the disk.
Reference for Replacing Hardware
The following table points to the procedures for replacing boards, Ethernet
cards, and disks, for each type of node.
