Identify a Disk Slot Using prtconf (Oracle Solaris, Single Initiator)

The procedure described below is intended for SPARC T3-1 and SPARC T3-4 servers in a single-initiator, eight-disk backplane configuration.

1. Run the format command.

   # format
   Searching for disks...done
    
   AVAILABLE DISK SELECTIONS:
       0. c0t5000CCA00ABBAEB8d0 <SUN300G cyl 46873 alt 2 hd 20 sec 625>
          /scsi_vhci/disk@g5000cca00abbaeb8
       1. c0t5000C5001D40D7F7d0 <SUN300G cyl 46873 alt 2 hd 20 sec 625>
          /scsi_vhci/disk@g5000c5001d40d7f7
   [...]

   The remaining steps in this example will identify the physical slot that corresponds to the device name c0t5000CCA00ABBAEB8d0.

2. Run prtconf -v and search for the device link c0t5000CCA00ABBAEB8d0.

   Device Minor Nodes:
       dev=(32,0)
           dev_path=/scsi_vhci/disk@g5000cca00abbaeb8:a
               spectype=blk type=minor
               dev_link=/dev/dsk/c0t5000CCA00ABBAEB8d0s0      <<=== Device path
               dev_link=/dev/sd3a
           dev_path=/scsi_vhci/disk@g5000cca00abbaeb8:a,raw
               spectype=chr type=minor
               dev_link=/dev/rdsk/c0t5000CCA00ABBAEB8d0s0     <<=== Device path
               dev_link=/dev/rsd3a

3. Search the prtconf output for a name=’wwn’ entry that has the WWN value 5000cca00abbaeb8.

   Note the obp-path value listed under WWN 5000cca00abbaeb8.

   Refer to the following table to find the controller.

   
   

   SPARC T3-1     Controller 0 /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@w5000cca00abbaeb9,0     Controller 1 /pci@400/pci@2/pci@0/pci@4/scsi@0/disk@w5000cca00abbaeb9,0 SPARC T3-4 (4 processor)     Controller 0 /pci@400/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0     Controller 1 /pci@700/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0 SPARC T3-4 (2 processor)     Controller 0 /pci@400/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0     Controller 1 /pci@500/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0

   For SPARC T3-1 servers,the controller is identified in the second field: pci@1 = controller 0 and pci@2 = controller 1.

   For SPARC T3-4 servers, the controller is identified in the first field. For systems with a four-processor configuration, pci@400 = controller 0 and pci@700 = controller 1. For systems with a two-processor configuration, pci@400 = controller 0 and pci@500 = controller 1.

   The following output example shows the obp-path for a SPARC T3-1 server.

   Paths from multipath bus adapters:
       mpt_sas#5 (online)
           name=’wwn’ type=string items=1
               value=’5000cca00abbaeb8’              <<=== Hard drive WWN ID
           name=’lun’ type=int items=1
               value=00000000
           name=’target-port’ type=string items=1
               value=’5000cca00abbaeb9’              <<=== Hard drive Target ID
           name=’obp-path’ type=string items=1
               value=’/pci@400/pci@1/pci@0/pci@4/scsi@0/disk@w5000cca00abbaeb9,0’
           name=’phy-num’ type=int items=1
               value=00000000
           name=’path-class’ type=string items=1
               value=’primary’

   In this SPARC T3-1 example, the obp-path is:

   /pci@400/pci@1/pci@0/pci@4/scsi@0/disk@w5000cca00abbaeb9,0

   Based on the previous table, this disk is on controller 0.

   The following output example shows the obp-path for a SPARC T3-4 server.

   Paths from multipath bus adapters:
       mpt_sas#5 (online)
           name=’wwn’ type=string items=1
               value=’5000cca00abbaeb8’              <<=== Hard drive WWN ID
           name=’lun’ type=int items=1
               value=00000000
           name=’target-port’ type=string items=1
               value=’5000cca00abbaeb9’              <<=== Hard drive Target ID
           name=’obp-path’ type=string items=1
               value=’/pci@400/pci@1/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0’
           name=’phy-num’ type=int items=1
               value=00000000
           name=’path-class’ type=string items=1
               value=’primary’

   In this SPARC T3-4 example, the obp-path is:

   /pci@400/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0

   Based on the previous table, this disk is on controller 0.

4. This phy-num value corresponds to physical disk slot 0, as shown in the following port mapping table.
   

   SAS Controller PhyNum Disk Slot SAS Controller PhyNum Disk Slot 0 0 0 1 0 4 1 1 1 5 2 2 2 6 3 3 3 7
