Storage Manager on ROM

RAID 0 arrays are comprised of any number of drives greater than 1.

RAID 1 arrays are comprised of multiple pairs of drives. RAID 5

arrays contain three or more drives.

After you create the arrays, one or more arrays of the same RAID

level can be combined into a multilevel RAID (see Creating a

Multilevel RAID on page 2-28). Arrays are striped into multilevel

RAIDs by the controller firmware. All the drives in an array or

multilevel RAID must be attached to the same controller, and appear

to the host as a single Logical Storage Unit (LSU).

Note: Arrays do not start building until a Set System Config

action has been performed.

The Array Information tab displays general array information and

hardware configuration. It is divided into either two or three parts:

Description, SCSI Capabilities (for SCSI based RAID controllers

only), and Status.

The Description section displays a general description of the

highlighted array, as follows:

Description RAID level used for the array.

Revision Firmware revision of the RAID controller.

Address RAID address in the form

dDbBtTdD, as described in

Device Address Syntax on page 4-2. Display contains as

much information as necessary to unambiguously

define the address of the device. Controllers always are

assigned the lowest logical address of any device in the

array.

Capacity The usable capacity of the array in MB. The available

capacity depends upon the RAID level of that array.

Removable

Read Only

As reported by the devices in the array.

Block Size The sector (block) size of the selected device in bytes.

For hard drives, the value should be 512. SCSI only—If

the size is not 512, use SMOR to do a low-level format

and create 512-byte sectors. See Formatting a Drive –

SCSI only on page 2-31 for more information.

Stripe Size Displays the stripe size used to create the RAID.
