COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED

Figure 2-1 shows an original distributed configuration with two controllers, each
having one array: drive IDs 0, 1, 2, and 3 constitute Array A on Controller 1 and
drive IDs 0 and 1 constitute Array A on Controller 2. Figure 2-2 shows that after
removing the array from Controller 2 and adding it to Controller 1, Controller 1
now has two arrays: drive IDs 0, 1, 2, and 3 constitute Array A and drive IDs 4
and 5 constitute Array B. Controller 2 has no arrays.

NOTE: A spare can be added as part of an array during this process.
However, it will not be restored as a spare until you run the Array Configuration
Utility on the newly configured array.
