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,
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.
