MC/ServiceGuard and Multiple IP Addresses per Package

[William DeJongh_1]

Can ServiceGuard run a package wih two IP addresses? We are going to run parallel networks during an infrastructure upgrade and hope to have the application accessable by both networks during the transition period. These two networks will have different subnets. We are thinking that we will need 4 network cards, 2 on each network.

Refer to page 55, Relocatable IP addresses.

"...In addition to the stationary IP address, you normally assign one or more
unique IP addresses to each package..."

"...It is recommended that you configure names for each package through DNS (Domain Name System)..."

So in your DNS add package names with ip addresses and alias's for same.

Hi,
Yes u can run a package with two IP address and u can have with different subnets.If you have 2 network cards per network it can be configured as redundant.

Yes it can, and in fact you can run a maximum of 200 relocatable IP addresses on a single cluster, and I think you can have all of those on a single package if that is what you wish.
The way you define it is to ensure that:
a) The subnets are in the Cluster ascii and binary files.
b) The package configuration file has the subnets listed, as in:
SUBNET[0] 192.1.0.0
SUBNET[1] 200.32.0.0

c) The package control file must have each subnet/IP pair listed, for example :
SUBNET[0]=192.1.0.0
IP[0]=192.1.0.3
SUBNET[1]=200.32.0.0
IP[1]=200.32.0.6
