HP-UX IPSec and MC/ServiceGuard

Step 2: Configuring HP-UX Host IPSec Policies for MC/ServiceGuard

•“Configuring Host IPSec Policies for ServiceGuard Manager” on page 251

•“Configuring Host IPSec Policies for Cluster Object Manager (COM)” on page 253

•“Summary: MC/ServiceGuard Port Numbers and Protocols” on page 254

Determining MC/ServiceGuard Cluster Information

Before configuring IPSec policies, determine the following information about the MC/ServiceGuard cluster:

•Heartbeat IP addresses

The heartbeat IP address for each cluster node is specified using the HEARTBEAT_IP parameter in the node definitions section of the cluster configuration file.

•Package addresses

The package addresses are configured using the IP[i] statements in the package control script.

Configuring Host IPSec Policies for Package Addresses

On the cluster nodes, configure host IPSec policies with source IP address set to the package addresses.

On the cluster clients, configure host ipsec policies with the destination address set to the package addresses.

Configuring PASS Host IPSec Policies for Heartbeat IP Addresses

Configure a PASS host IPSec policy (host IPSec policy with -action PASS) for each pair of heartbeat IP addresses in the cluster to ensure that MC/ServiceGuard heartbeat and intracluster control messages pass in clear text.

Since the IPSec configuration database is the same for all cluster nodes, you must configure a PASS host IPSec policy for each heartbeat IP address pair in the cluster.
