drive you want to rebuild by highlighting it. Press the spacebar to select the drive, F10 to start the
Rebuild, F2 to view drive information, and F3 to view logical drives.
Check Consistency
Choose this option to verify the redundancy data in logical drives using RAID levels 1, 3, 5, 10, 30,
or 50.
When you choose Check Consistency, the parameters of the existing logical drives on the current
adapter and a selection menu listing the logical drives by number appear.
Press the arrow keys to highlight the desired logical drives. Press the spacebar to select or deselect a
drive for consistency checking. Press F2 to select or deselect all the logical drives. Press F10 to
begin the consistency check. A progress indicator for each selected logical drive is displayed.
You may cancel a consistency check in progress by pressing Esc.
When the consistency check is finished, press any key to clear the progress display and press Esc to
return to the Management Menu.
Check consistency should be run if the system shuts down irregularly, e.g., if the system hangs or
suffers a power failure. It is also recommended to run consistency checks every 2-4 weeks to ensure
that bad blocks on the disk drive are mapped out. (See the “Check Consistency Feature.”) Check
consistency will always remedy inconsistencies. Check consistency will only fail because firmware
could not complete parity and data writes due to a power-failure or a system hang, or because the
logical drive degraded or failed due to the physical drives going offline.
Disable/Enable BIOS
Disables or enables the BIOS firmware. The default setting is Enabled. If the BIOS is disabled, DOS
cannot read logical drives, and one cannot boot from RAID.
C. Configuring Arrays and Logical Drives
Each configuration method requires a different level of user input. The general flow of operations
for array and logical drive configuration is described below.
1. Choose a configuration method.
2. Designate hot spares (optional).
3. Create arrays using the available physical drives.
4. Initialize the new logical drives.
Choosing a Configuration Method
Easy Configuration
In Easy Configuration, each physical array you create is associated with exactly one logical drive,
and you can modify the following parameters:
•
RAID level
•
Stripe size
•
Cache write policy
•
Read policy
•
I/O policy
If there are already logical drives configured when you select Easy Configuration, their configuration
information is not disturbed.
