Information in this document applies to any platform.

Goal

How to Identify a Failed Disk when Internal LSI Hardware RAID Volumes are configured (SPARC T3-x and T4-x)

Solution

There are three utilities that can be used for Hardware RAID configurations on the T3/T4 servers:

1) Sas2ircu (Utilizing the LSI RAID utility)

2) Raidconfig (Utilizing Oracle Hardware Management Pack)

3) Fcode (At the OBP level)

1) If using the LSI RAID utility, run the below commands to identify the drive "State" and "Slot #"

   # sas2ircu 0 display all
   # sas2ircu 0 status

   Example:

   Device is a Hard disk
         Enclosure #                              : 1
       Slot #                                   : 0
       SAS Address                          : 5000cca-0-1506-d5e1
           State                                : Failed
           Size (in MB)/(in sectors)            : 286102/585937499
       Manufacturer                            : HITACHI
       Model Number                          : H103030SCSUN300G

2) If using Oracle Hardware Management Pack (OHMP), run the below commands to identify the drive "Status" and "Slot"

   # raidconfig list all -v

   Example:

       Disk c0d1
         =========
       ID: c0d1
       Chassis: 0
       Slot: 3
       Node ID: PDS:xxxxxxxxxxx
       Mapped to Host OS: false
       Device: 02000000:1
       Disabled: false
       Status: OK

3) If using the Fcode utility, run the below commands from the ok prompt

   {0} ok show-devs
   {0} ok select <path to SAS controller device>
   {0} ok show-volumes
   {0} ok unselect-dev

   Example:

       {0} ok show-devs

         /pci@400/pci@1/pci@0/pci@4/scsi@0
       /pci@400/pci@2/pci@0/pci@4/scsi@0

       {0} ok select /pci@400/pci@2/pci@0/pci@4/scsi@0

{0} ok show-volumes

PLEASE NOTE: CMT systems, that have multiple internal LSI controllers, will require conversion to identify the physical disk location (please see the below path information):

LSI CONTROLLER PATH INFORMATION :

(For additional system controller path information, not listed below, please see Doc ID 1005907.1 - SPARC Platforms: Matrix of Recognized Device Paths)

SPARC T3-1 (8-Disk Backplane):

Controller 0: /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@ (Slot 0-3 = Disk 0-3)
Controller 1: /pci@400/pci@2/pci@0/pci@4/scsi@0/disk@ (Slot 0-3 = Disk 4-7)

SPARC T3-1 (16-Disk Backplane):

Controller 0: /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@ (Slot 0-7 = Disk 0-7)
Controller 1: /pci@400/pci@2/pci@0/pci@4/scsi@0/disk@ (Slot 0-7 = Disk 8-15)

SPARC T3-4 (4 processor):

Controller 0: /pci@400/pci@1/pci@0/pci@0/LSI,sas@ (PhyNum 0-3 = Disk 0-3)
Controller 1: /pci@700/pci@1/pci@0/pci@0/LSI,sas@ (PhyNum 0-3 = Disk 4-7)

SPARC T3-4 (2 processor):

Controller 0: /pci@400/pci@1/pci@0/pci@0/LSI,sas@ (PhyNum 0-3 = Disk 0-3)
Controller 1: /pci@500/pci@2/pci@0/pci@0/LSI,sas@ (PhyNum 0-3 = Disk 4-7)

SPARC T4-1:

Controller 0: /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@(Slot 0-3 = Disk 0-3)
Controller 1: /pci@400/pci@2/pci@0/pci@4/scsi@0/disk@(Slot 0-3 = Disk 4-7)
