This logical block contains the logical drive parameters, which include the
RAID mode (RAID0 = stripe; RAID1=mirror), the size of the stripes, number
of stripes, and number of physical drives in the array. This block starts with the
keyword LOGICAL_ARRAY and must be organized as follows:
LOGICAL_ARRAY :<Array Number>
RAID_MODE :<STRIPE/MIRROR>
STRIPE_SIZE :<STRIPE SIZE>
TOTAL_STRIPES :<Number of Stripes>
TOTAL_PHYSICAL_DRIVES :<Number of Physical Drives in Array>
5.4.3 Physical Drive Information
This logical block contains the physical drive number, drive ID, and drive size.
It starts with the keyword PHYSICAL_DRIVE and must be organized as
follows:
PHYSICAL_DRIVE :<Drive Number>
DRIVE_ID :<Drive ID>
DRIVE_SIZE :<Drive Size>
The logical blocks can be separated by blank lines. There can be any number of
blank lines. The lines within the logical block must be consecutive. Blank lines
are not allowed within the logical block. There are as many PHYSICAL DRIVE
INFO blocks as the number of drives participating in the array. All the
PHYSICAL DRIVE INFO blocks for a logical array must follow the LOGICAL
ARRAY INFO block before the start of next LOGICAL ARRAY INFO block.
SPARE ARRAY information cannot be included in the configuration file.
