RAID Level 1
ExpressNAV interface to determine the setup of
the array.
Hot Spare sleds
To set up RAID Level 1 with Hot Spare sleds
1 Connect to Diamond Storage Array services
(refer to
Accessing the Array
on page 17) and use
the CLI or enter ATTO ExpressNAV browser
interface Advanced CLI Configuration page.

4 The array is configured into one RAID Level 1
group with two Hot Spare sleds.
Exhibit 6.3-2 Mirrored stripe groups with LUN designations in a fully populated Diamond Storage Array. If sled 12 were
removed, the drives marked LUN 6 would be available but degraded (unprotected by mirroring). If both sleds 11 and 12 were
missing, LUN 6 would be unavailable.
