Solution Type Technical Instruction Sure Solution 1013116.1 : How to Verify the LSI RAID Controller is Functional on Sun Fire[TM] V215/V245, Sun Fire[TM] V440/V445, Sun Fire[TM] T1000/T2000.
PreviouslyPublishedAs 217968 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. 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:
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 <Document: 1005013.1> 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 MPT Version 1.05, Firmware Version 1.09.00.00 Target 0 Unit 0 Disk FUJITSU MAY2073RCSUN72G 0501 143374738 Blocks, 73 GB SASAddress 500000e013cadaa2 PhyNum 0 Target 1 Unit 0 Disk FUJITSU MAY2073RCSUN72G 0501 143374738 Blocks, 73 GB SASAddress 500000e013caf5d2 PhyNum 1 Target 2 Volume 0 Unit 0 Disk LSILOGICLogical Volume 3000 143112591 Blocks, 73 GB 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 <volumename> 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 <raid controller path>
{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 2 Members 143112591 Blocks, 73 GB Disk 1 Primary Online Target 4 SEAGATE ST973401LSUN72G 0556 Disk 0 Secondary Online Target 3 SEAGATE ST973401LSUN72G 0556 {0} ok unselect-dev {0} ok reset-all 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
