In NSS, you can mirror your software RAID 5 devices for your server to create a nested RAID 5+1 device. Use NSSMU to mirror the partition used by the pool on a RAID 5 device. The following procedure describes how to create the RAID 5+1 in NSSMU. You can also create the RAID 5 devices and NSS pool for the RAID 5 devices in the Storage plug-in for iManager, and then switch to NSSMU to mirror the pool’s partition.
In NSSMU, create a software RAID 5 device with 3 to 14 segments.
For information, see Section 13.6, Creating Software RAID Devices with NSSMU.
Repeat Step 1 one to three times to create 2 to 4 RAID 5 devices.
The RAID 5 devices you use to create the mirror must have no drives in common. Each drive you use to create the RAIDs can belong to only one of the RAID 5 devices.
In NSSMU, create a pool on one of the RAID 5 devices.
In NSSMU, select from the NSSMU main menu.
Press Insert (Ins) to create a pool.
From the list of available devices, select one of the RAID 5 devices.
Assign all of the available space to the pool, then press Enter.
Create a RAID 1 device to mirror the pool.
In NSSMU, select from the NSSMU main menu.
Select the NSS partition for the pool you want to mirror.
Press F3 to create the RAID 1 device and mirror the partition.
From the available devices, select one of the remaining RAID 5 devices you created above.
NOTE:You can select up to three devices.
Press F3 to initialize and create the RAID 1 (mirror) device.
After the RAID device is created, the device ID appears in the window. This window is viewed from the RAID Devices NSSMU main menu. The RAID is a RAID 5+1.
