41.4 Planning a New Library for a Clustered Post
Office
The considerations involved in planning a library in a Microsoft cluster are essentially the same as
for any other environment. You can plan a library for a new clustered post office by following the
standard instructions provided in “
Creating and Managing Libraries ” in the GroupWise 7
Administration Guide and filling out the “ Basic Library Worksheet ” or the “ Full-Service Library
Worksheet ”. Then provide the library information on the System Clustering Worksheet.
IMPORTANT: Do not create the new library until you are instructed to do so in Chapter 3, “Setting
Up a Domain and Post Office in a NetWare Cluster,” on page 43 .
41.5 Planning GroupWise Resource Groups
Resource groups ensure that resources that depend on each other fail over together. If your
GroupWise system is very small (for example, one domain and one post office), you could have a
single GroupWise resource group so that your whole GroupWise system would fail over together.
More typically, multiple domains and post offices are located throughout your organization, so you
would set up a resource group for each domain and post office.
A resource group for a domain or post office must include the following types of resources:
Š
Network Name: The virtual name by which the domain or post office resource group will be
known on the network, regardless of which node it is active on
Š IP Address: The virtual IP address that will be associated with the network name, regardless of
which node the domain or post office resource group is active on
Š
Physical Disk: The drive letter where the domain or post office directory will be located, used
when mapping a drive to the physical disk
Š
File Share: The name of the physical disk, used when mapping a drive to the physical disk
Š Generic Service: The GroupWise agent, running as a Windows service, that will service the
domain or post office
For convenience, you might want to name each resource group after the domain or post office it
represents. In this documentation, a resource group that could include a domain, a post office, or
both, is termed a “GroupWise resource group.”
Each GroupWise resource group has associated with it a list of possible owners. The possible
owners are the nodes to which the resource group could fail over. By default, a resource group is
configured to have all nodes in the cluster in its possible owners list, organized in ascending
alphanumeric order. Only one node at a time can have a particular GroupWise resource group active.
SYSTEM CLUSTERING WORKSHEET
Under Item 9: Document Storage Area Location , mark where you want to create the library’s
document storage area.
If the document storage area will be located outside the post office directory structure and outside the
cluster, specify a user name and password that the POA can use to access the server where the
document storage area will reside.
