HP Surestore Disk Array 12h and FC60 - Manual (Page 232)

232 Adding Disk Enclosures to Increase Capacity
Capacity Expansion Example
An example of expanding an Disk Array FC60 is shown in Figure 83 . 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 LUNs.
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 LUN on a separate channel, and also simplifies LUN management.
Note In the following example the terms “LUN” and “volume group” are used
interchangeably.
