Clear Component Flags
About the xtclear command.
Use the xtclear command to clear system information for selected components. Type commands as xtclear --option_name, where option_name is alert, reserve, or warn.
Clear all warnings in specified cabinet
For this example, clear all warnings in cabinet c13-2:
smw:~> xtclear --warn c13-2
Alerts, reserves, and warnings must be cleared before a component can operate. Clearing an alert on a component frees its state.
For more information, see the xtclear(8) man page.
