Configuring Your System to Install Boot-From-SAN
For hardware compatibility with ESX Server, see the Compatibility Guides available at www.vmware.com/support/resources/esx_resources.html.
Note: If you are using a preboot execution environment (PXE), a boot-from-SAN operation will fail and is not supported for this version of ESX Server. Only a local disk PXE installation is supported.
Installing the VMware Virtual SMP Product
ESX Server 2.5.4 supports upgrading from the following previous releases:
Note: Using the tar archive, upgrading directly from releases prior to ESX Server 2.0.1 upgrade patch 6 is not supported. To upgrade from ESX Server 1.5 or ESX Server 2.0.0 to ESX 2.5.4, upgrade first to ESX Server 2.0.1 with Upgrade Patch 6.
Note: During an upgrade from a previous ESX Server release to ESX Server 2.5.4, this upgrade installer reinstalls all default ESX Server RPMs. If you have modified any of the default ESX Server RPMs, these modifications will be overwritten during the upgrade.
To upgrade from previous versions of ESX Server to ESX Server 2.5.4, you may use either the installation CD-ROM or the tar archive.
Upgrading from a CD-ROM
This update will not be complete until you reboot the ESX Server. If you enter n, to indicate that you will not reboot at this time, ESX Server displays the warning message "Please reboot the server manually. Your virtual machines will not run properly until this is done." If you see this message, you must manually reboot the server to complete the driver update.
After the installation, a file named "perllocal.pod" is created in the / directory. The personal file is an unnecessary file created as a byproduct of the installation process. It can be safely deleted.
