How to configure a RAID volume with the internal Hard Drives on Oracle/SUN SPARC T4-1 and T4-2.

The RAID setup procedure below was tested in SPARC T4-1. This procedure also works on Netra SPARC T4-1 and T4-2.

1. At the Oracle ILOM prompt, disable auto-boot:

-> set /HOST/bootmode script=”setenv auto-boot? false”
Set ‘script’ to ‘setenv auto-boot? false’

2. Boot the system to OpenBoot PROM ({0} ok Prompt):

-> start /SYS
Are you sure you want to start /SYS (y/n)? y
Starting /SYS

-> start /SP/console
Are you sure you want to start /SP/console (y/n)? y

Serial console started. To stop, type #.
…
auto-boot? = false
{0} ok

 

3. View the preconfigured aliases:

{0} ok devalias

…..

scsi0 should be the alias for /pci@400/pci@1/pci@0/pci@4/scsi@0
and
scsi1 should be the alias for /pci@400/pci@2/pci@0/pci@4/scsi@0

……

4. Select scsi0 (HDD attached to SCSI0):

{0} ok select scsi0

Note: To Unselect a device:
{0} ok unselect-dev

5. View HDDs attached to scsi0:

{0} ok show-children

Target a
Unit 0 Disk HITACHI H109030SESUN300G A31A 585937500 Blocks, 300 GB
SASDeviceName ….. PhyNum 1

6. Create RAID 1, Mirror RAID for example:

{0} ok 9 a create-raid1-volume
Target 9 size is 583983104 Blocks, 298 GB
Target a 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] RAID1Demo
Volume has been created

7. Verify new RAID1 Volume:

{0} ok show-volumes
Volume 0 Target 381 Type RAID1 (Mirroring)
Name RAID1Demo WWID 0c88478f6c67b46b

FCode Commands:

show-children Lists all connected physical drives and logical volumes.
show-volumes Lists all connected logical volumes in detail.
create-raid0-volume Creates a RAID 0 volume (minimum two targets).
create-raid1-volume Creates a RAID 1 volume (exactly two targets).
create-raid1e-volume Creates a RAID 1e volume (minimum three targets).
delete-volume Deletes a RAID volume.
activate-volume Re-activate a RAID volume after the motherboard has been replaced.

Usage Example: 0 delete-volume, where 0 is volume 0
