AUTOSTIFLE
AUTOSTIFLE
Use the AUTOSTIFLE command to create a stifling window in which a repeatedly
failing processor is no longer automatically reloaded.
The window is used to limit the impact of a continuously failing processor.
num-times
is the number of reloads allowed within num-hours. The reload range is 0 through
10. Setting the number to zero disables the AUTOSTIFLE function. The default
value is 3.
num-hours
is the number of hours in the interval window. The hours range from 0 through 168.
Setting the interval to zero disables the AUTOSTIFLE function. The default value is
24.
Guidelines
•
You can use the abbreviation as in place of AUTOSTIFLE.
•
This command makes it possible to prevent a consistently failing processor from
creating a situation in which new dumps are created indefinitely. TFDS stops
dumping and reloading a processor when it fails num-times within num-hours.
•
This state is effective until the processor remains stable for num-hours, the TFDS
process is restarted, or a new AUTOSTIFLE command is issued (implicit reset).
Examples
•
This example causes TFDS to begin stifling if a processor goes down more than
twice in 24 hours:
AUTOSTIFLE 2,24
•
This example causes TFDS to begin stifling if a processor goes down more than
once in 4 hours:
AUTOSTIFLE 1,4
•
This example turns off stifling:
AUTOSTIFLE 0,24
AUTOSTIFLE num-times [,] num-hours
