Notes:
1. If you plan to use the Logical Drive Migration (LDM) feature, do
not define more than seven logical drives. The LDM feature
requires one free logical drive to perform the migration. Refer to
“Logical Drive Migration Administration” on page 112 for more
information.
2. If you plan to use the Change RAID Level function of the LDM
feature, you must assign the same RAID level to all logical drives
within a single disk array. Refer to “Change RAID Levels” on
page 112 for more information.
Initializing Logical Drives: Initializing a logical drive erases the
first 1024 sectors on the drive and prevents access to any data
previously stored on the drive.
To initialize a logical drive:
1. Select the desired logical drive from the Main screen of the
Administration and Monitoring Program.
2. Click on Initialize to initialize the drive.
3. If you have initialized a RAID level-5 drive, you must synchronize
to ensure data integrity. Go to “Synchronizing Logical Drives.”
Synchronizing Logical Drives: The purpose of synchronizing
logical drives is to compute and write the parity data on the selected
drives.
If the type of ServeRAID adapter or controller you are using does not
support the auto-synchronization and data-scrubbing features,
manually synchronize your RAID level-1 and RAID level-5 logical
drives weekly. This does not alter data on the drive.
Synchronizing a logical drive verifies that the data redundancy for the
logical drive is correct.
To synchronize a logical drive:
1. Select the desired logical drive from the Main screen of the
Administration and Monitoring Program.
