Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-39
Connecting to Shared Resources
In the traditional, command-driven connection to a shared resource, the user
needs to know the server name and the share name. In a clustered
environment, the command is changed to reflect the cluster network name and
file share that were configured as part of the failover group for that shared
directory.
Compare the command syntax in Table 2-3 for connecting to a shared resource
on a stand-alone server versus a clustered server.

Comparison of Net Use Command Syntax
Server Environment Command Syntax
Stand-alone server Net use J:\\servername\sharename
Cluster node Net use J:\\networkname\fileshare
Change client login scripts and profiles so that users connect to resources
using the cluster network name and file share.
Client/Server Applications
Reconfiguration of client applications in a client/server environment may also
be required. Some applications, such as many of the popular databases, require
the client to specify the IP address of the server that holds the database they
want to connect to. The IP addresses may be held in a special configuration
program or in a text file. Any references to the server's actual IP addresses
must be changed to reflect the new IP Address Resource that has been
configured for that application's cluster group.
Some databases allow you to specify the IP address of a backup server, which
the client database software attempts to use in case the database is not
accessible using the first IP address. The backup IP address scheme can be
used in a nonclustered environment to assist clients if the primary server fails.
This is no longer necessary when using MSCS.
