The vxibc unregister command unregisters an application name for the RVG.
To unregister an application name:
# vxibc [-g diskgroup] unregister application_name rvg_name
The application name must have been previously registered for the RVG. Further send operations against the application name are not possible after unregistering on the Primary RVG.
You can unregister the application on the Secondary if the following conditions are met:
If the IBC message has arrived on the Secondary and has been received by the user.
If the IBC message has arrived on the Secondary and not received by the user, but the delivery timeout period has expired.
If you used the vxibc regrecv command, you do not have to unregister the application.
