Frequently Asked Questions About Operating System Software Updates

Which versions of the operating system are compatible with operating system upgrade 2000.4.3a?

You can upgrade any Cisco MCS or Cisco-approved, customer-provided server that runs 2000.2.7 (or later) to 2000.4.3a, unless the server already runs 2000.4.3. The upgrade detects the current version that runs on the server; if the server does not run a compatible version, the upgrade aborts. If the server runs 2000.4.3, you cannot upgrade it to 2000.4.3a, but you can apply the 2000.4.3a service releases to get the fixes that are available in 2000.4.3a.

For other important considerations, see the “Important Considerations” section on page 6.

May I perform configuration tasks during the update?

Caution Do not attempt to perform any configuration tasks during the installation. Before you update the server, disable all services that allow any administrator to perform remote configuration tasks. For example, disable Terminal Services or VNC, if you do not plan to use it, before the upgrade to prevent an administrator from browsing into the server during the installation.

Notify all users that you are performing an installation, so users do not browse into the server.

Performing configuration tasks during the installation causes an installation failure.

May I use Terminal Services, VNC, or ILO on this server during an update?

Cisco installs Terminal Services, so Cisco Technical Assistance Center (TAC) can perform remote administration and troubleshooting tasks. Cisco does not support operating system installations, upgrades, or software updates through Terminal Services.

Caution Before the update, Cisco strongly recommends that you disable Terminal Services and immediately reboot the server to prevent remote access to the server. Accessing the server via Terminal Services may cause the update to fail. After you perform the update, you must enable Terminal Services.

If you want to use Virtual Network Computing (VNC) to remotely install supported applications, see Table 2 on page 5 to obtain the latest version of the VNC document.

Caution If you installed VNC but do not plan to use it to perform the update, disable it to prevent remote access to the server. If you do not disable VNC and a user/administrator accesses the server during the update, the update fails.

HP servers support Integrated Lights Out (ILO). If your server is a Cisco MCS (HP equivalent; for example, MCS-7835H-2.4) or Cisco-approved, customer-provided HP server, you can use ILO for remote configuration and monitoring tasks. Cisco does not support ILO for any other purposes, including installation and upgrade tasks.

To use ILO, you must obtain the ILO Default Network Settings tag that shipped with your server and perform all necessary startup tasks. To use this product, refer to the documentation that accompanies your hardware.
