Correlate WWN Device Names With Physical Locations (`diskinfo` Command)

The diskinfo command is available in Oracle Solaris. If you are using Oracle Solaris 11, this command is effective for all T5 series servers. If you are using Oracle Solaris 10, this procedure is only effective for the server modules, so other servers require the procedure in Correlate WWN Device Names With Physical Locations (probe-scsi-all Command). You also need to use that procedure if you do not have access to Oracle Solaris at the time you need to determine a name for a specific drive.

Log in to Oracle Solaris.

Display information about the drives on the server.
Note - This document applies to several server and server module products. The following example is based on the SPARC T5-1B server module. Your output might vary from the examples based on your product.

For example, on a SPARC T5-1B server module running Oracle Solaris 10 1/13:
```
# diskinfo -a
 
Enclosure path:          0000000-0000000000-physical-hba-0
Chassis Serial Number:   0000000-0000000000-physical-hba-0
Chassis Model:              sun4v-platform
 
Label       Disk Name               Vendor   Product           Vers
----------- ----------------------  -------- ----------------  -----
/SYS/HDD0   c0t5000CCA01622AC64d0   HITACHI  H109030SESUN300G  A31A
/SYS/HDD1   c0t5000CCA01622B1F4d0   HITACHI  H109030SESUN300G  A31A
```
In Oracle Solaris 11.1, you see output with similar information when you type:
```
# diskinfo -P SYS -o Rc
```
For further information, refer to the Oracle Solaris documentation or man page on the diskinfo command.

Look at the output under the Label and Disk Name columns to correlate a drive's physical location with its corresponding logical device name.
In this example for a SPARC T5-1B server module:
- /SYS/HDD0 represents a drive in slot 0.
- /SYS/HDD1 represents a drive in slot 1.
