Configuring a Redundant Disk Array

4. Select the RAID Properties option and press Enter.
5. Select the option for the type of RAID to create:
A. Select
Create IM Volume
to set up a RAID 1 mirroring volume.
Select two RAID hard disk drives to act as the primary and secondary mirror hard disk
drives, and optionally up to two hot spares in case the primary or secondary fails.
The first hard disk drive you select is the primary hard disk drive, which allows the option
to keep existing data. Data on a secondary hard disk drive is deleted.
B. Select
Create IME Volume
to set up a RAID 1E volume for mirroring with
enhancements.
Select at least three RAID hard disk drives to participate in the array, and up to two hot
spares in case a participating hard disk drive fails.
The first hard disk drive you select is the primary hard disk drive, which allows the option
to keep existing data. Data on each secondary hard disk drive is deleted.
C. Select
Create IS Volume
to set up a RAID 0 striping volume.
Select at least 3 hard disk drives to include in the array, with a maximum of 10. Data on
each hard disk drive in a striping array is deleted.
Note:
When two pairs of RTMs and CPMs are cabled together, the hard disk drives are
identified in the SAS BIOS screens by slot number instead of the SAS/SATA port number.
The identification is as follows:
Slot 0: Local RTM hard disk drive (on the RTM controlling the RAID)
Slot 1: Local HDD AMC hard disk drive
Slot 2: Remote RTM hard disk drive (when a custom crossover cable is used)
Slot 3: Remote HDD AMC hard disk drive (when a custom crossover cable is used)
When a standard crossover cable is used, slots 1 and 2 remain the same but slots 3 and
4 identify an external hard disk drive array.
The slot numbers correspond to the SAS/SATA controller port numbers in
Figure 3 on
page 17
.
6. Complete the array configuration by pressing C.
7. Save the changes when prompted.
Note:
When one array has been configured, use the Manage Array option to view, delete, or
modify the hot spares in the array. When multiple arrays have been configured, use the View
Existing Array option to select and manage an array.
For additional details about using the SAS BIOS screens to create an array, see the
Integrated
RAID for SAS User’s Guide
from LSI Logic Corporation.
