15.The window shown in Figure 4-70 allows you to create logical drives in all
defined arrays. The first logical drive in each array is already defined with the
maximum logical drive size. Enter a meaningful logical drive name. This
logical drive name will be part of the IQN of the device and is visible on the
iSCSI initiator. Select the RAID level. This RAID level is determined by the
number of drives in the array. For a spanned array, the number of drives in the
base array determines if a RAID 10 or 50 will be defined. Specify how large
the logical drive will be. Choose the preferred controller.
For our example, use a logical drive name COLORADO-BOOT-W. Specify RAID
level 1 and a size of 10GB for this logical drive. The logical drive and this array
will be owned by controller A.

16.In Figure 4-70, the Define new logical drive button creates a new logical
drive. The size will be the same as the remaining free space.
Select the logical drive COLORADO-BOOT-W and click the Replicate
logical drive button. A new logical drive with the same size is created as
shown in Figure 4-71 on page 123. The dropdown box with the number 1
specifies how often the logical drive is replicated. Up to 63 logical drives can
be replicated, depending on the remaining free space after creating each
replicated logical drive.
Assign the new replicated logical drive a name COLORADO-LOG.
