Maximum-Shutdown-Time negotiation

The Maximum Shutdown Time setting provides the delay needed to make

sure that a server will have enough time to shut down safely when a

graceful shutdown is initiated by the Management Card or by PowerChute

network shutdown client at the server.

The time reported by the Maximum Shutdown Time setting represents the

maximum delay needed by at least one of the servers listed in the

Configured Client IP Addresses list. This time is determined by a

negotiation process that is initiated when any of the following occurs:

• The Management Card turns on (a System: Coldstart event)

• The Management Card is reset (a System: Warmstart event)

• You select Force negotiation from the Maximum Shutdown Time

setting’s drop-down menu, and click Apply

During the negotiation process, which can take up to 10 minutes to perform,

each of the servers listed in the Configured Client IP Addresses list is

contacted to determine the shutdown delay needed by each server. At the

end of this process, the delay time defined by the Maximum Shutdown

Time setting will be changed, if necessary, to reflect the highest delay time

reported by the servers.

For information about the Turn UPS Off Gracefully, Reboot

UPS Gracefully, and Put UPS To Sleep Gracefully options

that use this delay, see UPS Control.
