Note
All new RAID level 5 logical drives are
automatically synchronized when you initialize
them.
Initializing logical drives:
Initializing a logical drive
erases the first 1024 sectors on the drive and prevents
access to any data previously stored on that drive. You
must initialize all new logical drives before storing data in
them.
To initialize a logical drive:
1. Select the logical drive that you want to initialize from
the Main Screen of the Administration and Monitoring
utility program.
A screen similar to the following appears.

2. Click on Initialize to initialize the drive.
Note
RAID level 5 logical drives are automatically
synchronized when you initialize them. You do
not need to synchronize RAID level 0 or 1 logical
drives before storing data.
Synchronizing logical drives:
The purpose of
synchronizing logical drives is to compute and write the
parity data on the selected RAID level 5 logical drives.
Synchronizing a RAID level 1 logical drive copies the data
from the primary disk to the mirrored disk.
RAID level 5 logical drives are automatically synchronized
when you initialize them. You do not need to synchronize
RAID level 0 or 1 logical drives before storing data. Also,
the
data scrubbing feature of the ServeRAID controller
continuously reads all sections of RAID level 1 and RAID
level 5 logical drives “in the background” while the system
