NOTE: When using Device Mapper Multipath, the path to the cluster Lock LUN, for example

/dev/mapper/mpath0p1, must be the same on each node.

• Select Check Configuration. Look for any errors.

NOTE: You may get a warning about the default NODE_TIMEOUT value. This warning can

be ignored here, but refer to the documentation when finalizing your cluster.

• Select Apply Configuration. Select “OK” in the pop-up dialog box.

• To verify the cluster configuration, run the following options from Administration menu of the

HP Serviceguard Manager Summary page to test that each node can run the cluster in the

event that the other node fails:

a. Administration -> Run Cluster (on both nodes)

b. Administration -> Halt Node (select adam)

c. Administration -> Run Node (on adam)

d. Administration -> Halt Node (select eve)

Configure a Sample Package

In this section, you will configure a Serviceguard for Linux package, called ws, for an Apache web

server using scripts from the Apache Toolkit. The content for the web server resides on the shared

volume group, vgws, and is accessed from a browser at a relocatable IP address. This way the user

browsing the content does not need to know which node is hosting the web server. Users can access

the web browser from using a single URL, regardless of which node is hosting the web server.
