HP SureStore E Disk Array FC60 Service Manual (A5635A)

182 Adding Disk Enclosures to Increase Capacity
Capacity Expansion Example
An example of expanding an Disk Array FC60 is shown in Figure 70. In this example, three
new disk enclosures are added to a disk array with three fully loaded enclosures. The disk
array is configured with five 6-disk volume groups.
The original enclosures were operating in split-bus mode, and have been reconfigured to
full-bus mode. The disks have been moved from their original locations to slots with the
corresponding channel:ID. This strategy achieves the desired result of having each disk in
the volume group on a separate channel, and also simplifies volume group management.
Note
In the following example the terms “LUN” and “volume group” are used
interchangeably.
