Hello Mohammed,
I am not aware of such command. Maybe you can grep the log files for events coming from the subsystem "chassis":
Procurve-5406# sh log -w | include chassis
12:22:49 00576 chassis: 50V Power Supply 1 is Faulted. Failures: 1
-> in this case the power supply #1 is faulted causing a flashing fault LED.
Cheers,
Michael
