Patching ESX Server
At the time of writing, patch version 27728 was the latest update for ESX Server 2.5.3. The patch process is generally similar for 2.5.x patches.
Proceed as follows:
1. Determine the Patch Revision from the Host SW Manifest tab of the PID.
2. Obtain the TAR archive containing the update from the Vmware website.
3. Power off all virtual machines and shutdown your server.
4. Restart your system.
5. At the LILO Boot Menu, select linux UP (linux Uniprocessor.)
6. Allow the system start procedure to complete.
7. Log in as root into the ESX Server service console, in Linux mode. Make sure your path variable contains /usr/bin:/bin.
8. Download the tar file into the temporary directory /tmp on the service console.
9. Change directories to /tmp.
10. Extract the compressed tar archive:
# tar -xvzf esx-2.5.3-27728-upgrade.tar.gz
11. Change directories to the newly created directory /tmp/esx-2.5.3-27728-upgrade:
# cd esx-2.5.3-27728-upgrade
12. Run the installer:
# /usr/bin/perl ./upgrade.pl
13. The system updates have now been installed. A reboot prompt displays:
Reboot the server now [y/n]?
