Goal

How to create a hardware RAID volume at the ok prompt.

Solution

The following RAID levels are supported:

RAID 0     -- Data striping
RAID 1     -- Data mirroring (using two disks)
RAID 1e   -- Enhanced mirroring (using three to eight disks)

NOTE: An exception is T3-4 and T4-4 where it is not supported.

1. Prepare to create a RAID volume.

Use the show-disks command to show the available controller paths. In this example controller 1 is desired. For T3-2 and T4-2 only one path is available. When asked for selection enter “q” to quit. Then use the select command and the controller string minus the “/disk” from the end.

{0} ok show-disks
a) /pci@400/pci@2/pci@0/pci@f/pci@0/usb@0,2/hub@2/hub@3/storage@2/disk
b) /pci@400/pci@2/pci@0/pci@4/scsi@0/disk
c) /pci@400/pci@1/pci@0/pci@4/scsi@0/disk
d) /iscsi-hba/disk
q) NO SELECTION
Enter Selection, q to quit: q
{0} ok
{0} ok select /pci@400/pci@2/pci@0/pci@4/scsi@0

2. Use the show-children command to list the physical drives on the selected controller.

     For example:
    {0} ok show-children
     
    FCode Version 1.00.54, MPT Version 2.00, Firmware Version 5.00.17.00
     
    Target 9
      Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
      SASDeviceName 5000c5001771776f  SASAddress 5000c5001771776d  PhyNum 0
    Target a
      Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
      SASDeviceName 5000c5001d0c38c7  SASAddress 5000c5001d0c38c5  PhyNum 1
    Target b
      Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
      SASDeviceName 5000c5001d097407  SASAddress 5000c5001d097405  PhyNum 2
    Target c
      Unit 0   Disk   SEAGATE  ST930003SSUN300G 0B70    585937500 Blocks, 300 GB
      SASDeviceName 5000c5001d09a51f  SASAddress 5000c5001d09a51d  PhyNum 3
    {0} ok
     

3. Use the create-raid0-volume, create-raid1-volume, or create-raid1e-volume command to create a logical drive from the physical disks.

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

    {0} ok 9 a create-raid0-volume

    For example, to create a RAID 1e volume with targets a, b, and c, type:

    {0} ok a b c create-raid1e-volume

    To verify creation of the volume, type:

    {0} ok show-volumes

    Type unselect-dev to deselect the controller.

    {0} ok unselect-dev

After the volume is created and Solaris is booted, the volume can be seen by the format utility. The volume may show messages about a corrupt label as shown when searching for disks, and again when the volume is selected, and finally asking “Disk not labeled.  Label it now?” to which the answer is yes.

Controller Paths

T3-1 T4-1
Controller 0 /pci@400/pci@1/pci@0/pci@4/scsi@0/
Controller 1 /pci@400/pci@2/pci@0/pci@4/scsi@0/

T3-4 T4-4 (4 proc)
Controller 0 /pci@400/pci@1/pci@0/pci@0/LSI,sas@0/
Controller 1 /pci@700/pci@1/pci@0/pci@0/LSI,sas@0/

T3-4 T4-4 (2 proc)
Controller 0 /pci@400/pci@1/pci@0/pci@0/LSI,sas@0/
Controller 1 /pci@500/pci@1/pci@0/pci@0/LSI,sas@0/

T3-2 T4-2
/pci@400/pci@2/pci@0/pci@e/scsi@0

T3-1b
Controller 0 /pci@400/pci@1/pci@0/pci@2/LSILogic,sas@0/

T4-1b
Controller 0 /pci@400/pci@1/pci@0/pci@c/LSI,sas@0
