ServiceGuard Manager Version A.03.00 Release Notes, Third Edition

Installing and Running ServiceGuard Manager

Chapter 1 35

“Connection Dropped” message ﬂash momentarily, but ServiceGuard will

maintain your connection. It will fail the connection over from one node

in a ServiceGuard cluster to another node in the same cluster.

ServiceGuard Manager gets its information by connecting to a server

with ServiceGuard A.11.12 or later. A component of ServiceGuard, the

Cluster Object Manager, polls the available subnets to discover other

ServiceGuard objects. It collects status and conﬁguration information,

and sends the information back to ServiceGuard Manager.

To set up the highly-available connection between ServiceGuard

Manager and server nodes in a cluster, follow these steps:

Create the package in a cluster with ServiceGuard. For viewing, use

ServiceGuard A.11.12 or later. For administration commands use

ServiceGuard A.11.14 or later.

See “Creating the Package Conﬁguration” chapter in the ServiceGuard

manual. All ServiceGuard manuals are posted on the web and you can

view or print them there. Go to http://www.docs.hp.com and click

High Availability; the products are listed alphabetically.

1. Get an IP address to use as the package’s relocatable address. You

can use nslookup to be sure the package name and IP address are

correctly associated in your DNS table.

2. When naming the package, choose one that your users will recognize,

such as Clus3Srvr. The ﬁrst time a user opens ServiceGuard

Manager they will see the Connect dialog box. They can type this

name in for Server. After that, the name will appear in a list every

time that user opens ServiceGuard Manager.

3. Make only these two modiﬁcations to the package conﬁguration ﬁle

template, and leave the defaults for the other ﬁelds:

• List the package nodes. For high-availability, it is best to list all

the nodes in the cluster.

• For the run and halt scripts pathname, specify the control script

name and path for the run and halt script. (The default path is in

the documentation.)

4. Open the control script template. Make just two modiﬁcations. These

will allow the connection between your client (ServiceGuard

Manager station) and the server (ServiceGuard A.11.12 cluster):
