6-10 Sun Fire V210 and V240 Servers Administration Guide • December 2005
If you want to customize the OpenBoot Diagnostics testing, you can set test-args
to a comma-separated list of keywords, as in this example:
6.5.2.1 test and test-all Commands
You can also run OpenBoot Diagnostics tests directly from the ok prompt. To do this,
type the test command, followed by the full hardware path of the device (or set of
devices) to be tested. For example:
Knowing how to construct an appropriate hardware device path requires precise
knowledge of the hardware architecture of the Sun Fire V210 and V240 servers.
