Chapter 2 Installing and Configuring Cisco HSI Software
Installing the Cisco HSI
Installing Multiple Cisco HSIs in a Redundant PGW 2200 Configuration
This section describes how to install and configure two Cisco HSI for use with a redundant Cisco PGW
2200 configuration (See
Figure 2-1).
Figure 2-1 Dual Cisco HSI with a Redundant PGW 2200 Configuration
Caution To ensure the successful installation of two Cisco HSIs, after Step 22 of the “Installing Cisco HSI”
section on page 2-5, provision the software for the active host first before proceeding to Step 1 below.
See “Configuring the Cisco HSI” section on page 2-12 for configuration information.
Only one active provisioning session is permitted, and provisioning is permitted only on the active
Cisco
HSI.
Exit the provisioning session on the active host and continue to Step 1 below. If software is not
provisioned after it is installed on the active host, the stand-by host is not synchronized with the active
host. As a result, a forced switchover might fail.
To install two Cisco HSIs for a redundant PGW 2200 configuration (a configuration with two
Cisco
PGW 2200 hosts), complete the following steps:
Step 1 Continuing from Step 22 of the “Installing Cisco HSI” section on page 2-5, exit server 1.
Step 2 Log in to server 2 as root and go to the # prompt.
Step 3 Insert the Cisco HSI CD-ROM in the CD-ROM drive.
Step 4 Follow the installation instructions found in Step 3 through Step 22 of the “Installing Cisco HSI” section
on page 2-5.
Installation of the dual Cisco HSI for a redundant PGW 2200 configuration is now complete. (See the
example configuration script in the following section.)
