Following is the typical sequence of tasks that must be performed to use IBC Messaging for off-host processing:
onfreezetask). Note that the updates to the Secondary data volume is frozen while the off-host processing task is in progress.
The single command
ibc can be used to perform this sequence of tasks. To use the
ibc command, you need to provide scripts named
postfreeze to perform the tasks in step 1, step 3, step 5, step 6, and step 8 respectively. The
ibc command uses these scripts with IBC Messaging to perform these tasks in sequence. For more information about the user-defined scripts, see Understanding the scripts used for the vradmin ibc command.
You can also use the
vxibc commands to perform off-host processing operations. For details on using the available
vxibc commands, see Using the In-band Control Messaging utility vxibc and the IBC programming API.
