ATTO Technology S-Class manual To set up RAID Level 10 with Hot Spare sleds

Page 75

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

3Type set QuickRAID0 0 to configure the array in JBOD mode.

4The array will update NVRAM. The Ready* displays.

5Type SaveConfiguration.

6Type FirmwareRestart to reboot the array.

7Reboot the host computer.

8Type DriveInfo when in CLI or access the Storage Management page of the ExpressNAV interface to determine the setup of the array.

Hot Spare sleds

To set up RAID Level 10 with Hot Spare sleds

1Connect to Diamond Storage Array services (refer to Accessing the Array on page 17) and use the Command Line Interface or enter ATTO ExpressNAV browser interface Advanced CLI Configuration page.

2Type set QuickRAID10 1 2

3Type SaveConfiguration Restart

4The array is configured into one RAID Level 10 group with two Hot Spare sleds.

Exhibit 6.5-1 Configuration of sleds in RAID Level 10: five mirrored pairs of sleds in one Virtual Drive and two Hot Spare non-mirrored sleds

1 Virtual Drive

2 Hot Spare sleds

Exhibit 6.5-2 QuickRaid10 first spans drives across sleds, then partners sleds into mirrored groups, then enables striping across the mirrored groups.

All configurations will not be available if the array has fewer than 24 physical drives in 12 physical sleds. For example, QuickRAID 10 1 will only work with a fully populated array. QuickRAID10 3 will work if sleds 9-12 are removed: LUNs 1 and 2 will be available but LUN 3 will not be available.
