Novell GROUPWISE 8 - INTEROPERABILITY Manual page 286

Because the agents must be installed as Windows services in a Microsoft cluster, you must initially
run the Agent Installation program for each node in the cluster so that the Windows services for the
agents get created, regardless of where you are planning to run the agents from. However, for
updates, you need to run the Agent Installation program only once if you are running the agents
from a shared disk.
The following sections can help you choose which installation location would be best for your
clustered GroupWise system:

Advantages of Installing to a Shared Disk
Using a
drive:\grpwise
When you update the agent software, you only need to update it in one place for a particular
domain or post office, not on every node in the resource group's possible owners list. This
prevents the potential problem of having a domain or post office fail over to a node where a
different version of the agent software is installed.
Having the agent startup files on the same node as the domain or post office makes them easy
to find.
If you change information in the agent startup files, you only need to change it in one place, not
on every node in the resource group's possible owners list.
If you want to back up the GroupWise data, you can back up the domain and/or post office
directories and the agent software from the same shared disk.
Disadvantages of Installing to a Shared Disk
Installing the agents on the same shared disk with a domain or post office does have some
disadvantages:
You must install the agent software each time you create a new domain or post office on a new
shared disk.
GroupWise administrators who are used to the GroupWise agents being installed in
c:\grpwise
You must remember where you installed the GroupWise agents when you update the agent
software. Accidently installing a GroupWise Support Pack to the default location of
c:\grpwise
software was installed to a shared disk.
Recommendation
Whichever method you choose, be consistent throughout the entire cluster. Either put all the
GroupWise agents on the shared disks with the domains and post offices they service, or put them all
in
c:\grpwise
offices, make sure there are no agent files in
at a later time.
