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.
