ClusterCATS Dynamic IP Addressing (Windows only) 337
8 Enter a new name for the computer in the Computer Name field. This name
corresponds to the new IP address that you just added. Do not change the
Domain field on this tab.
Note
The Computer Name on the Identification tab should only be a NetBIOS name,
not a fully-qualified host name (FQHN). For example,
support1.allaire.com is a
possible FQHN. The first portion of this FQHN (
support1) can be a NetBIOS
name.
support1 would also appear as the host name under the DNS tab in
Protocols. The domain under the DNS tab in this case would be
allaire.com.
The Domain field on the Identification tab is different; it has nothing to do with
DNS but only corresponds to your NT domain.
9 Close all open dialog boxes and restart the server.
10 For IIS 4.0: Reinstall the NT 4.0 Option Pack and then reboot your server.
For IIS 5.0 or NES: Skip this step.
11 For IIS 4.0: You may need to reconfigure your web sites using the Internet Service
Manager.
For IIS 5.0 or NES: Skip this step.
12 Reinstall any products which are configured as part of IIS, including ColdFusion
and ClusterCATS. This should include any products you uninstalled in step 3.
When you install ClusterCATS, you must select the "Server Failover" option
during the installation procedure.
Note
Do not create any clusters at this time.
13 Enable the ClusterCATS dynamic IP addressing scheme using the procedure
described in “Enabling ClusterCATS dynamic IP addressing” on page 337.
Enabling ClusterCATS dynamic IP addressing
Before enabling the ClusterCATS dynamic IP addressing, you must have already set
up a maintenance IP address for each Web server in the cluster as described in
“Setting up maintenance IP addresses” on page 335 and bound any Web sites to the
appropriate IP addresses. The maintenance IP address must be different from the IP
address associated with the Web site.
This section instructs you to create the cluster while the Web site is still bound to the
IP address. When creating a cluster, you should not specify the maintenance address.
Once you test the cluster, you can then remove the IP addresses from the Web sites
and reboot. ClusterCATS then creates the address dynamically when the server boots
up.
