system.
Among the list of devices, you should see the two interfaces specific to the Sun Dual
Gigabit Ethernet and Dual SCSI/P adapter you want to test, as shown in the
following example.
Note – The preceding device paths are examples. The actual device paths on your
system may be different from the examples shown here.
7. Use the
test
