I face the following problem with the installation of SQL 2000 on a MS cluster: I installed SQL server 2000 with SP3 on the first node. I clustered the database and automatically the executables of SQL were installed to the second node, except the service pack 3. So finally the first node has SQL 2000 with SP3 and the second node has SQL 2000 and I was obliged to shutdown the second node. Now I want to update the SQL SP3 on the second node too . How shall I proceed ? Install the SP3 on the first node again and it will be automatically installed on the second node ? or Install the SP3 on the second node directly? At this case the sql cluster resources must be located on the second node ? I appreciate a lot if anyone that has any experience on this problem would like to answer to me.
