The Real (and Virtual) Adventures of Nathan the IT Guy » ESX 3.02 to 3.5 update http://itknowledgeexchange.techtarget.com/information-technology Wed, 19 Jun 2013 13:47:04 +0000 en-US hourly 1 ESX Upgrades http://itknowledgeexchange.techtarget.com/information-technology/esx-upgrades/ http://itknowledgeexchange.techtarget.com/information-technology/esx-upgrades/#comments Sun, 22 Feb 2009 21:57:03 +0000 Nathan Simon http://itknowledgeexchange.techtarget.com/information-technology/?p=140 I just wanted to make a quick post to let everyone know that an ESX Update isn’t as painful as one would think. Just yesterday I took control of one of my clients ESX Servers from home via ILO(Integrated Lights Out. HP’s technology for Direct remote Access) and mounted the ESX 3.5 Update 3 ISO via the virtual media applet, shut the server down via Ilo, booted up from the ISO, and started the upgrade. Everyone always ask the same question, “What about my VMFS and Virtual Machines?” From my new found solid experience with the ESX Updater, I can safely say not to worry. The ESX Installer will find the ESX Installation and upgrade ESX while maintaining all Virtual Machines and configurations. Mind you all my tests and actual implementations were on Servers with local storage, no iSCSI. And I know there have been issues for many users, ie iSCSI Targets disappearing after ESX Update. a quick google search will lead you to many different scenarios and solutions. The one issue i did run into was a SCSI Tape drive that was mounted in the main DC, i just had to quickly edit the machine configuration and select the HP Tape Device, for some reason some obscure device was mounted(old target ID i guess), either way once that was fixed, all the VMs booted fine, and I was back in business. Any questions or concerns, you know where to find me :)
