Return codes

The linkedCl returns 0 as the return code. Only if the cluster is removed AHAFS_CLUSTER_REMOVE (-1) is returned.

Event producer message

This event producer passes LINK_UP or LINK_DOWN messages as part of its event data. It will pass the LINK_ID information. Also, as it is a cluster event producer it will additionally pass NODE_NUMBER, NODE_ID and CLUSTER_ID information.

Acceptable monitor files

To monitor for changes in the list of nodes, a monitor file should be created under the linkedCl.monFactory directory. The monitor file name

/aha/cluster/linkedCl.monFactory/linkedClEvent.mon

has to be used. No other monitor files may be created in this directory.
