Building Disk Arrays - Hitachi Compute Blade 500 Series User Manual

Note: Do not change the disk array during system operations. If you
change the disk array, all data will be lost from those disks due to change in
the disk array.
Note: Set each item to the recommended value unless otherwise specific
directions are given. If not, the system may not properly operate.

Building disk arrays for RAID 0, 1, 5, 6
This section describes the procedure for building new disk arrays for RAID 0,
1, 5, and 6.
Note: RAID0 with a single disk does not have redundancy. When an error
occurs in a disk, all data in the disk may be lost. We recommend that RAID1/
RAID5/ RAID6/ RAID10 should be created to improve fault tolerance with
data redundancy.
Tip: To build RAID 10, refer to
4-40. For how to set hotspare, refer to
