You can manually create an array drive by using two or more logical drives that were manually
created at level 2. This action combines the original host drives associated with each of the logical
drives into a single host drive at a chosen RAID level.

Level 4: Host Drives

Host drives (RAID volumes) are created at the highest level of the hierarchy by the RAID
firmware. This is done automatically upon the creation of an array drive. It is also done
automatically upon the manual creation of a logical drive. Each host drive is assigned a drive
number that matches the drive number of its array drive or logical drive. Host drives are the only
hierarchal level drives that are detectable by the host operating system. The three lowest level
hierarchal drives are transparent to the host operating system.
After a capacity expansion of a given array drive, the added capacity appears to the host OS as a
new host drive on this level. It can then be configured as a separate host drive or, using the 'Merge'
feature in the Host Drive menu, be combined with the initial host drive of the array drive into one
single host drive.
Warning: Any data located on the new host drive (created from the capacity expansion) will be lost using the
Merge feature. Do not use this feature if the new host drive already contains data that you do not
wish to destroy.
Within the Storage Console utility, each level of hierarchy has its own special menu:
