Use probe-scsi-all to display the following SAS device information:
SASDeviceName -- This is the WWN that the Oracle Solaris OS recognizes.
SASAddress -- This is the WWN that the OBP recognizes.
PhyNum -- This is a hexadecimal value that identifies the port that a disk is connected to.
VolumeDeviceName -- When a RAID volume has been configured, this is the RAID volume WWN value recognized by the Oracle Solaris OS.
VolumeWWID -- When a RAID volume has been configured, this is the RAID volume’s WWN value referenced by OBP.
The following example is based on a SPARC T3-2 server with six hard drives. Four hard drives are connected to the SAS controller as individual storage devices. These are Target 9, d, e, and f. Two hard drives are configured as a RAID volume. This disk array is Target 389.
In the following example, the hard drive installed in physical slot 0 has the PhyNum value 0. It is designated Target 9 and has a SASDeviceName value of 5000c5001cb4a637.

Note - The probe-scsi-all output example shown above can be applied to the interpretation of probe-scsi-all output for SPARC T3-1B systems.
Note - The probe-scsi-all output for SPARC T3-1 and SPARC T3-4 servers has special characteristics due to their use of two on-board SAS controllers. In addition, on SPARC T3-1 servers with sixteen-disk capable backplanes, the two controllers connect to the hard drives through a SAS expander unit on the backplane. These differences are explained in probe-scsi-all Output Example (SPARC T3-1, Eight-Disk Backplane) and probe-scsi-all Output Example (SPARC T3-1, Sixteen-Disk Backplane).
