Configuring a partially-populated array The simplest way to attain RAID Level 5 in a partially-populated array (an array with three or more sleds but less than 12 sleds) is to create one RAID Level 5 group, with or without hot spare

sleds, encompassing all the available sleds by using the CLI command QuickRAID5 ALL.

To set up a partially populated arrays, you must have at least three sleds filling contiguous slots as shown in Exhibit 6.4-4,beginning with the slot closest to the management card.

Exhibit 6.4-4 Examples of RAID Level 5 configurations in partially-populated array with at least six sleds. Hot Spare sleds are in the highest slot numbers.

To set up RAID Level 5 groups

1Connect to Diamond Storage Array services via the RS-232 port or the optional Ethernet management services card (refer to Accessing the Array on page 17). You should now be in the CLI.

2Continue with the CLI or access the RAID page of the ExpressNAV interface (refer to ATTO ExpressNAV: Browser-based Interface on page 25).

Note

Because the ExpressNAV pages take you through this process easily, the following instructions are based on the CLI commands. Use these instructions as a guide in ExpressNAV.

3Decide the RAID Level 5 configuration you want based on the number of sleds you are using and Exhibit 6.4-4above.

4Type set QuickRAID5 [2 3 4 ALL]

5Type SaveConfiguration Restart to save the RAID Level 5 configuration.

6A Ready prompt displays. You must zero all drives and parity to make all RAID Level 5 drives coherent. Type RAID5ClearData all

CAUTION

This is a destructive operation: all information stored on these drives is lost.

DO NOT interrupt power until the RAID5ClearData operation has completed (three to six hours).
