Interactive Diagnostic Commands
When diagnostics are executed manually (from the Fabric OS command line),
many commands require the switch/blade to be in an offline state. This ensures
that the activity of the diagnostic does not interfere or disturb normal fabric traffic.
If the switch/blade is not in an offline state (
switchdisable or
bladedisable ), the diagnostic command will not run and display an
error message. No one diagnostic can give a complete assessment of the viability
of all the hardware. The diagnostic commands must be used together to get an
overall picture of the health of the switch or blade. If an area of the hardware is
suspected of having a fault, then a set of diagnostic commands can be used to
isolate and validate the functionality of the hardware.
A series of tests are captured and structured to allow hardware validation and fault
isolation. These have been captured in the
bladediag and
bladediagshort commands. These commands run a set of tests in certain
combination and in various modes to allow a trained user to evaluate the integrity
of the hardware, and enable insight as to where a hardware fault is originating.
