acquire_service_addr

(If configured for IP address takeover.)

 

Configures boot addresses to the corresponding

 

service address, and starts TCP/IP servers and

 

network daemons by running the telinit -a

 

command.

acquire_takeover_addr

The script checks to see if a configured standby

 

address exists, then swaps the standby address

 

with the takeover address.

get_disk_vg_fs

Acquires disk, volume group, and file system

 

resources.

node_up_remote

Causes the local node to release all resources

 

taken from the remote node and to place any

 

concurrent volume groups in concurrent mode.

 

Some of the scripts called by node_up_remote

 

include the following:

release_takeover_addr

(If configured for IP address takeover.) Identifies

 

a takeover address to be released because a

 

standby adapter on the local node is

 

masquerading as the service address of the

 

remote node. Reconfigures the local standby

 

adapter to its original address (and hardware

 

address, if necessary).

stop_server

Stops application servers belonging to the

 

reintegrating node.

release_vg_fs

Releases volume groups and file systems

 

belonging to a resource group that the remote

 

node will be taking over.

cl_deactivate_nfs

Unmounts NFS file systems.

node_up_complete

This event occurs only after a node_up event

 

has successfully completed. Depending on

 

whether the node is local or remote, this event

 

initiates either a node_up_local_complete or

 

node_up_remote_complete event.

node_up_local_complete Calls the start_server script to start application servers. This event occurs only after a node_up_local event has successfully completed.

node_up_remote_completeAllows the local node to do an NFS mount only after the remote node is completely up. This
