To define a RDY drive as a hot-spare drive:

3. Select Define/Undefine Hot Spare Drive from the

Enabling or disabling hot-swap rebuild:
The
default setting for the hot-swap rebuild parameter is
Disable. When you set the hot-swap rebuild parameter to
Enable, the ServeRAID controller can automatically rebuild
a defunct (DDD) drive when you replace it.
The ServeRAID controller will rebuild a defunct drive
automatically when all of the following conditions exist:
Ÿ
The hot-swap rebuild parameter is set to Enable.
Ÿ
The defunct drive is part of a RAID level 1 or RAID
level 5 logical drive.
Ÿ
The capacity of the replacement drive is equal to or
greater than the capacity of the defunct drive.
Ÿ
No rebuild, synchronization, or RAID level change
operation is in progress.
When these requirements are met, the ServeRAID
controller automatically initiates a rebuild of the drive
without user intervention.
To enable or disable hot-swap rebuild:
1. Start the ServeRAID configuration program (see
“Starting the ServeRAID Configuration program” on
page 77).
2. Select Advanced Functions from the Main Menu;
then, press Enter.
3. Select Display/Change Adapter Parameters from
the next menu; then, press Enter.
4. Select Enable/Disable Hot-Swap Rebuild; then,
press Enter.
