#### `probe-scsi-all` Output Example (SPARC T3-1, Sixteen-Disk Backplane)

When analyzing `probe-scsi-all` output, look for this 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 WWN value referenced by OBP.

The following table shows the PhyNum-to-disk slot correspondence for a sixteen-disk backplane connected to onboard SAS controllers 0 and 1.

Note - The default 16-disk backplane configuration is divided into two logically isolated zones, with disk slots 0-7 visible to SAS controller 0 and disk slots 8-15 visible to SAS controller 1.

Table 13 SAS Controller Port Mapping for Sixteen-Disk Backplanes

SAS Controller | PhyNum (Hex) | Disk Slot (Dec) |  | SAS Controller | PhyNum (Hex) | Disk Slot (Dec)
--- | --- | --- | --- | --- | --- | ---
0 | 0 | 0 |  | 1 | 8 | 8
| 1 | 1 |  |  | 9 | 9
| 2 | 2 |  |  | A | 10
| 3 | 3 |  |  | B | 11
| 4 | 4 |  |  | C | 12
| 5 | 5 |  |  | D | 13
| 6 | 6 |  |  | E | 14
| 7 | 7 |  |  | F | 15

The following example illustrates `probe-scsi-all` output for a SPARC T3-1 server with nine hard drives in a sixteen-disk capable backplane configuration.

Note - Controller 1 manages the SATA DVD.

The default boot location (physical slot 0) is listed as `PhyNum` `0` in the SAS controller 0 section. It has a `SASDeviceName` value of `5000cca00a59278c` and a `SASAddress` value of `5000cca00a59278d`.
