logical drive that is in the okay (OKY) state. During the
LDM procedure, the ServeRAID controller changes the
state of the FRE logical drive to SYS; then, temporarily
uses the SYS drive to perform the migration. When the
migration procedure completes, the ServeRAID controller
changes the state of the SYS drive back to FRE.
Changing RAID levels:
To use the Change RAID Level feature, all of the logical
drives within the array must be the same RAID level.
The ServeRAID controller supports changing RAID levels
as follows:
Ÿ
Change two RAID level 0 logical drives to RAID level 5
by adding one hard disk drive
Ÿ
Change two RAID level 1 logical drives to RAID level 5
by adding one hard disk drive
Ÿ
Change from RAID level 5 to RAID level 0 by
removing one hard disk drive
To change the RAID level:
1. Click on the icon on the tool bar or select
Manage Disk Arrays from the Advanced pull-down
menu; then, select Logical Drive Migration.
A screen similar to the following appears.
Logical Drive Migration
Logical Drive Migration Options
Change RAID Level
Add Physical Drive(s)
OK
Cancel
2. Select Change RAID Level; then, click on OK.
You can change (migrate) the RAID levels of
currently defined logical drives. Depending
upon the current RAID level, you might need
to add or remove a hard disk drive before you
can change the RAID level.
