You use the cphaprob command to verify cluster functionality and to debug cluster related problems. This section provides a brief overview of the cphaprob command and its command options. For complete documentation and use cases, refer to the R77 ClusterXL Administration Guide.
A critical device is a process running on a cluster member that enables the member to notify other cluster members that it can no longer function as a member. The device reports to the ClusterXL mechanism regarding its current state or it may fail to report, in which case ClusterXL decides that a failure has occurred and another cluster member takes over. When a critical device (also known as a Problem Notification, or pnote) fails, the cluster member is considered to have failed.
There are a number of built-in critical devices, and the administrator can define additional critical devices. The default critical devices are:
Cluster interfaces on the cluster members.
Synchronization — full synchronization completed successfully.
Filter — the Security Policy, and whether it is loaded.
fwd — the VPN‑1 daemon.
You can include these commands in scripts for automatic execution.
