required. When settings are desired, delete the factory settings
(logical volumes, RAID groups, and LUN mappings) and then
create your own RAID groups. For setting deletion details, refer to
the "ETERNUS DX60/DX80 Web GUI User Guide".
• For RAID5 and RAID6, ensure that a single RAID group is not
being configured by too many disks. Doing so may increase the
time to perform Rebuild/Copyback when a disk fails.
• Disks with different capacities can be installed in a single Drive
Enclosure. However, all disks configuring a RAID group should be
of the same capacity. Do not include disks with a different
capacity in a RAID group.
CAUTION

Data may not be recovered if a disk fails because RAID0
configuration is not redundant. RAID1, RAID1+0, RAID5,
RAID5+0 , and RAID6 are recommended as the RAID level.
