reconfig_resource_completeThis event indicates that a cluster resource 

dynamic reconfiguration has completed.

To tailor event processing to your environment, specify commands or 
user-defined scripts that should execute before and/or after a specific event 
is generated by the Cluster Manager. You specify them by selecting the 
HACMP event to be customized on the smit hacmp -> Cluster 
Configuration -> Resources -> Cluster Events -> Change/Show Cluster 
Events

 

screen, and then, choosing the one to be tailored. Now, you can 

enter the location of your pre- or post-event to be executed before or after the 
chosen event has been processed. 

For preprocessing, for example, you may want to send a message to specific 
users informing them to stand by while a certain event occurs. For 
post-processing, you may want to disable login for a specific group of users if 
a particular network fails. 

You can specify a command or user-defined script that provides notification 
(for example, mail) that an event is about to happen and that an event has 
just occurred, along with the success or failure of the event.

This is done on the very same SMIT screen as in 5.1.2, “Pre- and Post-Event 
Processing” on page 122 in the 

Notify

 Command field.

For example, a site may want to use a 

network_down

 notification event to 

inform system administrators that traffic may have to be rerouted. Afterwards, 
you can use a 

network_up

 notification event to tell system administrators that 

traffic can again be serviced through the restored network.

Event notification in an HACMP cluster can also be done using pre- and 
post-event scripts, just by adding the script you want to execute for 
notification into the 

pre-

 and/or 

post-event

 command script.

You can specify a command that attempts to recover from an event command 
failure. If the retry count is greater than zero, and the recovery command 
succeeds, the event script command is rerun. You can also specify the 
number of times to attempt to execute the recovery command.
