The examples in this procedure apply to a SPARC T5-4 server that has an eight-disk backplane configuration.

The remaining steps in this example identify the physical slot that corresponds to the device name c0t5000CCA00ABBAEB8d0.
For this example, the following portion of the output includes that device name:
Device Minor Nodes: dev=(32,0) dev_path=/scsi_vhci/disk@g5000cca00abbaeb8:a spectype=blk type=minor dev_link=/dev/dsk/c0t5000CCA00ABBAEB8d0s0 <<=== Device link dev_link=/dev/sd3a dev_path=/scsi_vhci/disk@g5000cca00abbaeb8:a,raw spectype=chr type=minor dev_link=/dev/rdsk/c0t5000CCA00ABBAEB8d0s0 <<=== Device link dev_link=/dev/rsd3a
Note the obp-path value listed under WWN 5000cca00abbaeb8.
Refer to the following items to find the controller.
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
For SPARC T5-4 servers, the controller is identified in the first field. For servers with a four-processor configuration, pci@400 is controller 0 and pci@700 is controller 1.
The following output example shows the obp-path for a SPARC T5-4 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 SAS address 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 example, the obp-path is:
/pci@400/pci@1/pci@0/pci@0/LSI,sas@0/disk@w5000cca00abbaeb9,0
Based on the earlier name identification, this disk is on controller 0.
This phy-num value corresponds to physical disk slot 0.
