initiAlizAtiOn
Initialization is done to logical drives after they are created from a disk array. Full initialization sets all data bits
in the logical drive to a specied pattern, such as all zeros. The action is useful because there may be residual
data on the logical drives left behind from earlier congurations. For this reason, Initialization is recommended
for all new logical drives. See “Initializing a Logical Drive” on page 206.
PArtitiOn And fOrMAt
Like any other type of xed 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 xed disk.
Depending on the operating system you use, there may or may not be various capacity limitations applicable
for the different types of partitions.
Caution
When you initialize a logical drive, all the data on the logical drive is
lost. Backup any important data before you initialize a logical drive.
