This document guides you through confirming the integrity of your ESX/ESXi Server install or upgrade media.
For typical ESX/ESXi Server installations and upgrades, an ISO image of a CD/DVD is downloaded from VMware. You then record that file onto a CD/DVD-ROM, and boot the ESX/ESXi Server host from that disc. If you have a production CD/DVD-ROM from VMware and it is version 3.x, and want to check the integrity, go to the CD/DVD-ROM Media Test section below. Checking the Download Integrity If you are downloading an ISO from VMware. It is a good idea to to check the integrity of the downloaded file, prior to recording to a CD/DVD-ROM. The steps below outline how to do this: Create an MD5 checksum of the downloaded file. For more information, see Using MD5 Checksums . Compare the newly created MD5 checksum with the MD5 checksum published by VMware. If the checksums match, the images are identical, record the file to CD/DVD-ROM and go to the CD/DVD-ROM Media Test section outlined below (only for 3.x). If the checksums do not match, download the image again. Consider these alternatives: If you have a choice of file types to download, like .exe or .zip, try the other type(s). Use a different web browser. Use a different program for downloading. Use a different computer and/or a different operating system (perhaps using a virtual machine). Repeat steps 1 - 4 until the checksums match. When the checksums match, record the file to CD/DVD-ROM and proceed to the CD/DVD-ROM Media Test section. CD/DVD-ROM Media Test For ESX Server 3.0.x and ESX Server 3.5.x installations and upgrades, a CD media integrity test is one of the first steps of the installation or upgrade. Note: For ESXi 3.x - 5.x and ESX 4.x you'll want to complete the above steps to verify your media, there is no test media option from CD/DVR-ROM in these versions. After choosing whether you want to complete a graphical or text installation, you see this screen: Click Test to have the installer inspect the installation CD/DVD-ROM media for errors.If you click Skip, the installation or upgrade continues, skipping the integrity check.If you click Test, a progress bar appears. The CD/DVD-ROM media is being tested for errors. When testing is complete, a Media Check Result dialog box appears. Click OK.If the test fails, try recording the image onto CD/DVD-ROM again, repeating until the test succeeds. Consider these alternatives:Using a high quality CD-R/DVD+-R media.Recording at a slower speed.Using a different recording program.
