DOCUMENT:Q174799 09-AUG-2001 [winnt] TITLE :How to Install Service Packs in a Cluster PRODUCT :Microsoft Windows NT PROD/VER::2000,4.0 OPER/SYS: KEYWORDS:kbsetup ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server, Enterprise Edition version 4.0 - Microsoft Windows 2000 Advanced Server ------------------------------------------------------------------------------- SUMMARY ======= This article outlines the procedure for installing a Service Pack on Microsoft Windows Clustering. The process of applying a Service Pack to a server cluster is the same as applying it to Microsoft Windows 2000 or Microsoft Windows NT 4.0 Enterprise Edition Server. However, special consideration must be taken to ensure a high level of access for clients when you perform this system maintenance. NOTE: You must install Service Pack 3 (SP3) at the end of the Windows NT 4.0 Enterprise Edition installation to complete the installation. This is the only scenario where you cannot bypass a previous Service Pack and apply a later one. MORE INFORMATION ================ You can install Windows NT Server and Windows 2000 Service Packs on server cluster nodes using the following procedure. Always install the same Service Packs or hotfixes to each node. Use this procedure to install the Service Packs unless otherwise directed by a particular Service Pack version. 1. Check the System event log for errors and ensure proper system operation. 2. Make sure you have a current backup and updated emergency repair disk for each system. In the event of corrupt files, power outage, or incompatibility, it may be necessary to revert back to the state of the system prior to attempting to install the Service Pack. 3. Open Cluster Administrator, right-click Node A, and then click Pause Node. 4. Right-click Node A, click Move Group for all groups owned by Node A to move all groups to Node B. 5. Install the Service Pack on Node A, and then restart the computer. 6. Check the System event log for errors. If you find any errors, troubleshoot them before continuing this process. 7. In Cluster Administrator, right-click Node A, and then click Resume Node. 8. In Cluster Administrator, right-click Node B, and then click Pause Node. 9. Right-click Node B, and then click Move Group for all groups owned by Node B to move all groups to Node A. 10. Install the Service Pack on Node B, and then restart the computer. 11. Check the system event log for errors. If you find any errors, troubleshoot them before continuing this process. 12. In Cluster Administrator, right-click Node B, and then click Resume Node. 13. Right-click each group, click Move Group, and then move the groups back to their preferred owner.
