#### `probe-scsi-all` Output Example (SPARC T3-4)

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.

A SPARC T3-4 server has two onboard SAS controllers, each connected to a separate four-disk capable backplane. The following table shows the PhyNum-to-disk slot correspondence for these backplanes.

Table 14 SAS Controller Port Mapping for an Eight-Disk Backplane

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

Note - OBP uses a different device path for SAS controller 1 in SPARC T3-4 servers, depending on whether the server has four-processors or two processors. The path for SAS Controller 0 is the same for both processor configurations.

##### SAS Controller Device Path: SPARC T3-4 Server With Four Processors

The following example illustrates `probe-scsi-all` output for a SPARC T3-4 with four processors and eight drives.

Because SAS controller 0 controls the hard drives installed in backplane slots 0-3, the default boot device for this example is PhyNum 0 in the group of hard drives under controller 0. It has a `SASDeviceName` value of `5000cca00a75dcac` and a `SASAddress` value of `5000cca00a75dcad`.

##### SAS Controller Device Path: SPARC T3-4 Server With Two Processors

The following example illustrates `probe-scsi-all` output for a SPARC T3-4 with two processors and eight drives.

Because SAS controller 0 controls the hard drives installed in backplane slots 0-3, the default boot device for this example is PhyNum 0 in the group of hard drives under controller 0. It has a `SASDeviceName` value of `5000cca00a75dcac` and a `SASAddress` value of `5000cca00a75dcad`.
