The BlackDiamond system provides a facility for running normal or extended
diagnostics on an I/O module or a Management Switch Fabric Module (MSM) without
affecting the operation of the rest of the system.
If you select to run the diagnostic routine on an I/O module, that module is taken
off-line while the diagnostic test is performed. Traffic to and from the ports on the
module are temporarily unavailable. Once the diagnostic test is completed, the I/O
module is reset and becomes operational again.
You can run normal or extended diagnostics on the slave MSM. The normal diagnostic
routing is a short series of tests that do not test all the internal ASIC functions. The
extended diagnostic routine tests coverage of all MSM components including the
internal ASIC functions. The slave MSM is taken off-line while the diagnostic test is
performed. It is reset and operational once the test is completed.
If you want to run the diagnostic routine on the master MSM, you must set it in
diagnostic mode and then reboot the switch. When you reboot, the master MSM
becomes the slave MSM (and vice versa) so that the diagnostic routing can be
performed.
To run the diagnostic routine, use the command
run diag [normal | extended] [<slot> | a | b]
where the following is true:
•
[normal | extended]
— selects the diagnostic routine
•
<slot>
— specifies the slot number of an I/O module
•
a | b
— specifies the slot letter of an MSM
