SPARC T8 Series Servers Administration Guide

Create a Hardware RAID Volume (FCode-based RAID Utility)

1. Select the controller that will handle a new RAID volume.

   See Prepare to Create a RAID Hardware Volume (FCode-based RAID Utility). At this point you have obtained the OpenBoot prompt and have selected an on-board disk controller.

2. List the physical drives on the selected controller.

   Note the target name of each disk you will use in the RAID. In this example, the targets are named 9, a, b, and c.

   ok show-children
   ...
   Target 9
     Unit 0   Disk   HITACHI  H109060SESUN600G A690    1172123568 Blocks, 600 GB
     SASDeviceName 5000cca0566c32b4  SASAddress 5000cca0566c32b5  PhyNum 0
   Target a
     Unit 0   Disk   HITACHI  H109060SESUN600G A690    1172123568 Blocks, 600 GB
     SASDeviceName 5000cca0566cfac4  SASAddress 5000cca0566cfac5  PhyNum 1 
   ok

3. Type one of these commands to create a logical drive from several physical disks:

   • create-raid0-volume

   • create-raid1-volume

   • create-raid1e-volume

   • create-raid10-volume

   For example, to create a RAID 0 volume with targets 9 and a, type the targets first then type the command name:

   ok 9 a create-raid0-volume
   

   To create a RAID 1e volume with three targets (a, b, and c), type:

   ok a b c create-raid1e-volume
   

   To create a RAID 10 volume with four targets (9, a, b, and c), type:

   ok 9 a b c create-raid10-volume
   

4. Verify creation of the RAID volume.

   ok show-volumes
   

5. (Optional) Create a second RAID volume to be handled by the present controller.

   To do so, enter another command as described in Step 3.

6. Unselect the controller.

   ok unselect-dev
