Creating RAID1 Using the FCODE Facility (from OBP) in Oracle SPARC T3-2 Server

1. List the device paths on the server

ok show-devs

Look for lines ending with scsi@0. We had only one controller.

/pci@400/pci@2/pci@0/pci@e/scsi@0

2. Select the controller:

ok select /pci@400/pci@2/pci@0/pci@e/scsi@0

ok show-volumes

No volumes to show

If volumes are present then can be removed by selecting the appropriate controller and using delete-volume. In case there are two controllers you need to delete volumes on both.

3. To create a RAID1 volume to mirror the boot disks, show-children command was used to list the physical drives on the selected controller:

ok show-children

FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.00.17.00

Target 9

  Unit 0   Disk   HITACHI  H106030SDSUN300G A2B0    585937500 Blocks, 300 GB

  SASDeviceName 5000cca012c84f98  SASAddress 5000cca012c84f99  PhyNum 0

Target a

  Unit 0   Removable Read Only device   ###TEAC    DV-W28SS-R      1.0C                    ########################################

  SATA device  PhyNum 7

Target b

  Unit 0   Disk   HITACHI  H106030SDSUN300G A2B0    585937500 Blocks, 300 GB

  SASDeviceName 5000cca01298f514  SASAddress 5000cca01298f515  PhyNum 1

4. Create a RAID 1 volume with (in our case) targets 9 & b:

ok 9 b create-raid1-volume

Target 9 size is 583983104 Blocks, 298 GB

Target b size is 583983104 Blocks, 298 GB

The volume can be any size from 1 MB to 285148 MB

What size do you want?  [285148 #]

Volume size will be 583983104 Blocks, 298 GB

Enter a volume name:  [0 to 15 characters] RAID1

Volume has been created

5. Verify creation of the volume:

ok show volumes

ok show-children

The hardware RAID1 volume was successfully created. Notice that show-volumes still displays (Mirroring) with both disks as 'Optimal'. Now we can go ahead with the OS installation on the created RAID1 volume.
