HP-UX Secure Resource Partitions (SRP) A.02.01 Administrator's Guide

following example, the representative Serviceguard package was modified to add a default route,

external_script:

Before:

# SG ip address

ip_subnet 192.10.25.0

ip_address 192.10.25.12

After:

# SG ip address

ip_subnet 192.10.25.0

ip_address 192.10.25.12

# srp_route_script configures the required source based routing entries

for

# the SG managed IP addresses

external_script /etc/cmcluster/pkg1/srp_route_script

See

Appendix B SRP Serviceguard Default Route Script for an example of the srp_route_script script.

16.4 Creating Serviceguard Scripts for the SRP Package Model

The SRP package model manages the SRP itself as a package. At start time, the package starts the

SRP and relies on the SRP initialization process to mount any application specific file systems and start

the applications. Similarly, at stop time, the package stops the SRP relying on SRP to perform any

application shutdown and file system unmounting.

Monitoring of the package is accomplished using the same method as described for the classic

model. The SPR package model allows you to share the entire SRP home directory between primary

and secondary SRPs. If you choose to share a common home directory, then the Serviceguard

package should mount and unmount the home directory before starting and stopping the SRP. See

5.2 Managing SRP Startup and Shutdown Actions.

Either SRP or Serviceguard can manage the network interfaces. If Serviceguard is managing the

network interfaces, HP recommends that you instruct Serviceguard to configure the default route for

any SRP IP address. See Appendix B SRP Serviceguard Default Route Script for an example.

You can find a reference implementation of the SRP package model at:

To create a functional example of a working SRP based on a Serviceguard package, follow the

instructions as specified in the following file:
