## Identify a Disk Slot Using `probe-scsi-all` (OBP)

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`.

- Run `probe-scsi-all`.

  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).
