180 RAIDCFG
-r

-raid
0, 1, 5, 6, 10, 50,
60
Sets the RAID type or level for the
virtual disk.
NOTE: If this option is not specified for
any RAID controller, RAID 0 is taken as
the default.
The valid arguments are:
• 0 — RAID 0 uses data striping,
which is writing data in equal-sized
segments across the array disks.
RAID 0 does not provide data
redundancy.
• 1 — RAID 1 is the simplest form of
maintaining redundant data. In
RAID 1, data is mirrored or
duplicated on one or more drives.
• 5 — RAID 5 provides data
redundancy by using data striping in
combination with parity
information. Rather than
dedicating a drive to parity, the
parity information is striped across
all disks in the array.
• 6 — RAID 6 is an extension of
RAID 5 and uses an additional
parity block. It uses block-level
striping with two parity blocks
distributed across all member disks.
RAID 6 provides protection against
double disk failures and failures
while a single disk is rebuilding. In
case there is only one array, RAID 6
may be a better option than a
hotspare disk.
• 10 — RAID 10 is a stripe of mirrors.
Multiple RAID 1 mirrors are
created, and a RAID 0 stripe is
created over these.
