A quiesced server has a weight of 0, which is the same value as a server that is detected down by the advisor. If you run a unquiesce command on a quiesced server, the executor function saves a value of 0 for the weight that determines if the state of the server has changed. When the server is unquiesced, the serverUp script might run because of this saved value.
dscontrol manager quiesce server
dscontrol manager unquiesce server
If
the unquiesce command occurs after the manager has retrieved the weights,
the executor function overwrites the weight that is used to determine
if the server state has changed. This process does not cause any side
effects unless the server is also quiesced.The chances of experiencing this problem increase with larger configurations because the manager cycle takes longer to run. Also, there is a higher probability that the manager cycle will be in progress when the unquiesce command is issued.
