Figure 3-27 Add LUN(s) Screen
To add a LUN to an existing configuration, at least one LUN must already exist. In
addition, unconfigured disks must be available with enough disk space to create an
additional LUN.
2. Follow essentially the same procedures as before listed under “New Configuration”
on page 38.
The procedure that is followed and the screens that appear are similar to adding a
new configuration to an unconfigured controller. The differences are as follows:
• All previously defined LUNs and packs (which are actually used in LUNs) are
displayed when selecting drives for packs. The allocated drives, however, do
not have an empty checkbox in them (only unused disks have an empty
checkbox).
• You may not add a drive to an existing pack. To do this, you must use the
Expand LUN button (see Figure 3-25) to perform an online R AID e xpansion
procedure.
