Partition and Format the Logical Drive
Like any other type of fixed disk media in your system, a RAID logical drive must
also be partitioned and formatted before use. Use the same method of
partitioning and formatting on an logical drive as you would any other fixed disk.
Depending on the operating system you use, there may or may not be various
capacity limitations applicable for the different types of partitions.
RAID Level Migration
To
migrate
a disk array is to do one or both:
•
Change its RAID level
•
Increase the number of disk drives (sometimes called Expansion)
Migration takes place on an existing Functional disk array without disturbing the
existing data. While the disk array is migrating, you can access the data as
before. When migration is complete, your disk array will have a different RAID
level and/or a larger capacity.
Different types of disk arrays use different organizational models and have
varying benefits. The following outline breaks down the properties for each type
of RAID supported by Promise products.
