The Server Status Is “Down”
If a server is running but HP Clustered File System shows it as down,
follow these diagnostic steps:
1. Verify that the server is connected to the network.
2. Verify that the network devices and interfaces are properly configured
on the server.
3. Ensure that the ClusterPulse process is running on the server.
4. Verify that the same version of HP Clustered File System is installed
on all servers in the cluster.
HP Clustered File System Considers a Running
Service Down
If HP Clustered File System indicates that a service is down even though
it is running, the service might not be sending any information to HP
Clustered File System. HP Clustered File System will conclude that the
service is down even if the TCP connection succeeds. In particular, if an
HTTP server is monitored by a FTP monitor, the HTTP server is
considered down.
Also check the following:
1. Verify that the server is connected to the network.
2. Verify that the network devices and interfaces are properly configured
on the server.
3. Ensure that the ClusterPulse process and the service monitor agent
(monitor_agent) are running on the server.
A Virtual Host Is Inaccessible
If a site is inaccessible but HP Clustered File System indicates that it is
okay, verify that the service is running and that the actual data exists on
the server providing the network interface currently used by the virtual
host.
