##### `probe-scsi-all` WWN Mapping Example (Netra SPARC T4-2)

The Netra SPARC T4-2 server has two SAS2 RAID controllers on the motherboard. Each controller is connected to four slots on the disk backplane. One controller also connects to the DVD slot.

The following table shows the PhyNum-to-disk slot mapping for the Netra SPARC T4-2 backplane.

SAS2 Controller | Controller Port (PhyNum) | Disk Slot ID | Target |  | SAS2 Controller | Controller Port (PhyNum) | Disk Slot ID | Target
--- | --- | --- | --- | --- | --- | --- | --- | ---
0 | 01 | 0 | 9 |  | 1 | 0 | 4 | 9
| 1 | 1 | a |  |  | 1 | 5 | b
| 2 | 2 | b |  |  | 2 | 6 | c
| 3 | 3 | c |  |  | 3 | 7 | d
|  |  |  |  |  | 6 | DVD | a

1Default boot drive

The following example is based on a Netra SPARC T4-2 server with eight hard drives.

Note - Target values are not static. The same storage device can appear in two consecutive `probe-scsi-all` listings with different Target values.

The default boot device has the following values:

- Controller = 0

- Target = 9

- PhyNum = 0

- SASDeviceName = `5000cca0120f9dbc`

- SASAddress = `5000cca0120f9dbd`

If you want to specify another drive to be the boot device, find its `PhyNum` value in the output and use the `SASDeviceName` assigned to that device. For example, if you want to use the hard drive in disk slot 3, it has the following values:

- Controller = `0`

- Target = `c`

- PhyNum = `3`

- SASDeviceName = `5000cca01260f594`

- SASAddress = `5000cca01260f595`
