For ease of reference, the steps refer to the primary Branch Server as BS1 and the secondary Branch Server as BS2. Substitute your own server names as necessary.

  1. On the secondary Branch Server (BS2), stop Heartbeat by entering the command rcheartbeat stop.

  2. Upgrade the primary Branch Server (BS1) to the latest SLES 9 support pack release, following the steps in the Novell Linux Point of Service 9 Support Pack Readme.

  3. Reboot BS1.

  4. Upgrade BS1 to the latest Novell Linux Point of Service 9 support pack release, following the steps in the Novell Linux Point of Service 9 Support Pack Readme.

  5. Restart Heartbeat on BS2 with the command rcheartbeat start.

  6. Stop Heartbeat on BS1 and wait for BS2 to become the primary.

  7. Repeat Steps 2 through 4 to upgrade SLES 9, reboot the server, and upgrade the Novell Linux Point of Service 9 software on BS2 (the secondary Branch Server now acting as the primary).

  8. On BS1, enter rcheartbeat start to switch it back to being the primary Branch Server.

  9. After updating the Branch Servers, turn off automatic startup of the dhcp, named, and atftpd services during boot by entering the following commands on both servers:

    chkconfig dhcpd off chkconfig named off chkconfig atftpd off

  10. Enable automatic startup of Heartbeat by entering the following command:
