Description
This document provides a reference to the procedure for re-activating an existing RAID volume, on Sun Fire[TM] T1000/T2000, V215/V245, SRARC Enterprise T5120/T5220, T5140/T5240 and T5440 Servers. If you have an existing RAID volume and have to replace the raid controller on one of these servers, you'll need to run some OBP commands in order to see the volume with the new board. The outlined procedure includes generic instructions, as well as platform specific instructions.

Steps to Follow

When the RAID controller for internal disks has been replaced, customers may need to  re-activate the RAID volume by using OBP commands.
For T2000 systems, if using CPU/mem board part number 501-6843, the controller is a plug-in PCI-X card, part number 370-7696.
For all other instances on the T2000, T1000, V215/V245, T5120/T5220, T5140/T5240 and T5440, the controller is on the system board (motherboard).

Generic instructions for T1000, T2000, V215/V245, T5x20 and T5x40:
  {0} ok setenv fcode-debug? true
  {0} ok setenv auto-boot? false
  {0} ok reset-all

Path select instructions for T1000/Erie (dual-disk configuration is required for RAID operations):
  {0} ok select /pci@7c0/pci@0/pci@8/scsi@2

Path select instructions for T2000/Ontario (pn 501-6843):
  {0} ok select /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2

Path select instructions for T2000+/Ontario+ (pn 501-7501):
  {0} ok select /pci@780/pci@0/pci@9/scsi@0

Path select instructions for V215/V245/Seattle:
  {0} ok select /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1

Path select instructions for  T5120/T5220/Huron:
  {0} ok select /pci@0/pci@0/pci@2/scsi@0

Path select instructions for  T5140/T5240/Maramba:

  {0} ok select /pci@400/pci@0/pci@8/scsi@0/
 
Path select instructions for  T5440/Batoka:

  {0} ok select /pci@400/pci@0/pci@1/scsi@0/


Generic instructions for T1000, T2000, V215, V245, T5x20, T5x40:
  {0} ok show-volumes ( Look for the inactive volume)
  {0} ok X activate-volume (X is the volume number)
  {0} ok unselect-dev
  {0} ok probe-scsi-all (to check for disks)

When dealing with multiple volumes make sure they are activated in descending order:

Generic instructions for T1000, T2000, V215, V245, T5x20, T5x40:
  {0} ok show-volumes
  {0} ok 1 activate-volume
  {0} ok 0 activate-volume
  {0} ok unselect-dev
  {0} ok probe-scsi-all (to check for disks)

Failure to do so will result in the following error and will require a reset-all prior to activating the second volume:

  {0} ok 0 activate-volume
  Volume 0 is now activated
  {0} ok 1 activate-volume
  RAID volume request failed, ioc-status = 0007
  Volume 1 could not be activated

Following activation the first volume will remain 'Degraded' until both volumes have completed syncing.
