Planning and Documenting an HA Cluster
Hardware Planning
Chapter 4134
Hardware Planning
Hardware planning requires examining the physical hardware itself.
One useful procedure is to sketch the hardware configuration in a
diagram that shows adapter cards and buses, cabling, disks and
peripherals. A sample diagram for a two-node cluster is shown in
Figure 4-1.
NOTE Under agile addressing, the storage units in this example would have
names such as disk1, disk2, disk3, etc. See “About Device File Names
(Device Special Files)” on page 111.
