Description
This document describes how to determine that the LSI RAID controller for the internal hardware RAID is functioning properly. This applies to Sun Fire[TM] V215/V245, Sun Fire[TM] V440/V445, and Sun Fire[TM] T1000/T2000.

Solution

Steps to Follow
To Verify the LSI RAID Controller is Functional:

The Sun Fire V215/V245, Sun Fire V440/V445 and Sun Fire T1000/T2000 servers support the following RAID configurations:

Integrated Stripe, or IS volumes (RAID 0)

Integrated Mirror, or IM volumes (RAID 1)

The internal LSI RAID disk controllers LSI1064E (V215/V245, T1000/T2000), as well as LSI1068X/E (V445) support up to 2 hardware RAID volumes (IM or IS) of the same RAID-level at any one time. Prior to volume creation, ensure that the member disks are available and that there are not two volumes already created.

The on-board controller LSI1030 on V440 supports only RAID1 (integrated mirror) between any 2 internal disks. Creating a second RAID1 volume is not possible.

There are several ways to verify that the raid controller is functional:

a) Using the OBP commands 'probe-scsi-all', for proper usage of this command refer to probe-scsi-all may fail without 'reset-all' on all Sun Systems .

In the following example (for Sun Fire T2000 with the onboard LSI1064E controller), the 'probe-scsi-all' output has 2 internal drives and one RAID volume:

{0} ok probe-scsi-all
/pci@780/pci@0/pci@9/scsi@0

b) Using the 'raidctl' command, which is the Solaris tool to manage RAID operations. This command allows you to verify both the RAID status and the DISK status:

# raidctl

RAID    Volume  RAID            RAID            Disk
Volume  Type    Status          Disk            Status
------------------------------------------------------
c0t2d0  IM      OK              c0t2d0          OK
c0t3d0          OK

There is a new version of the 'raidctl' utility introduced with Solaris 10 8/07. The command usage and output changed. It now requires "raidctl -l to get volume and disk status (see example below):

# raidctl -l Controller: 1 Volume:c1t0d0 <--- new RAID volume Disk: 0.0.0 Disk: 0.1.0 Disk: 0.2.0 Disk: 0.3.0

# raidctl -l c1t0d0    <----- to get the details
Volume                  Size    Stripe  Status   Cache  RAID
Sub                     Size                    Level
Disk
----------------------------------------------------------------
c1t0d0                  273.3G  64K     OPTIMAL  N/A    RAID0
0.0.0   136.6G          GOOD
0.1.0   136.6G          GOOD

c) Using the OBP procedure to select the RAID controller path (node) and display the existing volumes and their status:

{0} ok setenv auto-boot?  false
{0} ok setenv fcode-debug?  true
{0} ok reset-all
{1} ok select 
{0} ok show-volumes  (to display the volume status)

Example (for T2000):

{0} ok select /pci@780/pci@0/pci@9/scsi@0
{0} ok show-volumes
Volume 0 Target 2  Type IM (Integrated Mirroring)
Optimal  Enabled

Here is a summary of the device paths for the LSI disk controller on the different servers listed in this document:

V440: /pci@1f,700000/scsi@2

V445: /pci@1f,700000/pci@0/pci@2/pci@0/pci@8/LSILogic,sas@1

V215: /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1

V245: /pci@1e,600000/pci@0/pci@a/pci@0/pci@8/scsi@1

T1000: /pci@7c0/pci@0/pci@8/scsi@2

T2000 systems using factory installed PCI-X card (370-7696): /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2

T2000 systems with on-board controller: /pci@780/pci@0/pci@9/scsi@0
