WebScale™
Installing Software Upgrades
WebScale is designed to be easily and dynamically upgraded in the field without
interrupting service by the cluster. To upgrade your WebScale cluster, apply the
upgrade (as described below) to each host in turn and then restart it so that it can rejoin
the cluster. The host does not need to leave the cluster while you upgrade the software
on it, and the cluster can remain operational throughout the upgrade process. The latest
release of WebScale is always made compatible with previous releases so that newly
upgraded hosts can join the cluster seamlessly.
You can always obtain the latest version of WebScale from Intergraph Computer
Systems, Inc. Be sure to read the README text file included with a new release for
installation tips and the latest information.
To upgrade WebScale on each host, follow these steps, which are very similar to the
initial steps for WebScale's original installation:
æ
Unpack the installation files to a diskette or to a single directory on your hard
drive.
æ
Run the Windows NT Network setup dialog.
æ
Select the WebScale Virtual NIC adapter from the list of network adapters.
æ
Click on the Modify button, which should be enabled.
æ
When you are prompted for a directory path, enter the path to the diskette or
directory containing the new WebScale files.
æ
When Windows NT displays the WebScale Setup dialog, configure the new
parameters as required.
æ
Click on the OK button to complete the installation.
æ
Restart Windows NT to load the new version of WebScale and to allow this host to
rejoin the cluster.
You can also upgrade your software license to allow expanded use of WebScale
features. For example, you may obtain a new license to increase the maximum number
of hosts in the cluster, to add port rules, or to enable other features. To do this, please
contact Intergraph Computer Systems, Inc. and obtain new initial and full license keys.
(Please refer to the Licensing Information section for more details on license keys.)
After you have obtained the keys:
æ
Run the WebScale Setup dialog from either the Windows NT Network setup dialog
or by running the webscale setup command.
æ
Enter either the initial or full license key as required.
