Solution Type Problem Resolution Sure Solution 1471121.1 : Some or all internal disks in SPARC T3 / T4 Servers may not show up in "# format" or "ok> probe-scsi-all"
In some factory configurations of T3 or T4 Servers none or not all internal disks may be visible in probe-scsi-all or format. In this Document
Applies to:SPARC T3-1 - Version All Versions and laterSun Storage 6Gb SAS PCIe HBA, 8 Port - Version Not Applicable and later SPARC T3-2 - Version All Versions and later SPARC T4-1 - Version All Versions and later SPARC T4-2 - Version All Versions and later Oracle Solaris on SPARC (64-bit) SymptomsCommon Symptoms are: - Cannot see any or more than one disk in "# format" or "ok> probe-scsi-all" although more than one physical disk is installed /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0/disk
CauseSPARC T3/T4 Systems may come configured with internal Disk Backplane connected to a 8-Port 6Gbps SAS-2 RAID HBA (Niwot). SolutionThe physical disks connected to 8-Port 6Gbps SAS-2 RAID HBA need to be configured.1) If a running Solaris instance is available, go to LSI Support Webpage http://www.lsi.com/sep/Pages/oracle/sg_x_sas6-r-int-z.aspx to download Software required to operate the 8-Port 6Gbps SAS-2 RAID HBA. The HBA may be operated in CLI mode with MegaCLI or in GUI mode with MegaRAID Storage Manager. 2) If there is no Solaris instance on the Server - or the disks need to be reconfigured before reinstallation of the OS - the disks can be configured using the PreBoot CLI (pcli) at OBP. - use the show-disks command to identify the path to the 8-Port 6Gbps SAS-2 RAID HBA
{0} ok show-disks
- select the HBA to run the pcli commands {0} ok select /pci@400/pci@2/pci@0/pci@c/LSI,mrsas@0

- type cli -PdList to identify Enclosure Device ID and physical drives
Example:
- type cli -CfgLdAdd -r0[252:0]
This will create a single disk LUN ( -r0 for RAID 0, with Enclosure #252 physical disk Slot 0 ).
- to display Information about the newly created LUN, type cli -LdInfo -L0
Example:
{0} ok cli -LdInfo -L0
