RAID Configuration and Management
IMPORTANT:
RAID configurations do not support a stripe size less than 32 KB. The stripe
size of an array that already has been configured
cannot
be changed.
—
Drive Size
—displays the size of the array and cannot be edited. If the array
type is RAID 0, then the drive size is the total of all the drives selected. If the
array type is RAID 1, drive size is shown by the smaller of the two drives
making up the array.
—
Build Array
—is
used to rebuild the array using a spare drive. When Build
Array starts, it prompts the user to select the target drive, and then the rebuild
starts. This option applies only to RAID 1 and RAID 1+0 arrays.
—
Initialize Array
—is used to clear the configuration information from drives
attached to the Integrated ATA RAID controller.

Delete Array (F5)
—allows the user to delete a currently configured array.
Restore Old Configuration (F6)
—restores the configuration that was there
before accessing the utility.
Edit Options (F7)
—edits the physical drive option status boxes located in the
top right corner of the
Physical Drive Information
window. The options are as
follows:
—
WC-OFF
—enables or disables write cache.
CAUTION:
Enabling write cache may cause data loss or corruption during an
unexpected loss of power.
—
DMA-ON
—enables or disables DMA (direct memory access) transfers, in
which data is transferred directly from the memory to the hard drive without
microprocessor intervention.
Pressing the
F7
key allows the user to enable or disable these options. Press the
F7
key, move the cursor to the desired box, and then press the spacebar to check off the
option. When enabled, the option status boxes change from red to green.
•
Save and Exit (F10)
—saves the configuration and exits the utility.
