Comments for VMtoday http://vmtoday.com VMware News, Views, & How-To's from Josh Townsend Mon, 22 Feb 2010 19:38:06 +0000 http://wordpress.org/?v=2.9.2 hourly 1 Comment on vSphere Upgrade Breaks Active Directory by Dan http://vmtoday.com/2009/11/vsphere-upgrade-breaks-active-directory/comment-page-1/#comment-490 Dan Mon, 22 Feb 2010 19:38:06 +0000 http://vmtoday.com/?p=249#comment-490 Thanks for the post - I upgraded a bunch of dev/test VMs over the weekend and ran into the WINS setting issue. Haven't done any DCs yet, but I do have two that I'll be upgrading over the coming weeks, so it's good to see this before it bites me. I also ran into another hitch. On Server 2008 and 2008 R2 guests, my second virtual disk (for the E: drive) came up offline on the first bootup after the virtual hardware upgrade. This appears to be a default in 2008 when a new disk is detected with an existing volume, since I've had it happen with SAN LUNs before too. I had to manually set the disk online in Disk Management for the volume to be mounted. Thanks for the post – I upgraded a bunch of dev/test VMs over the weekend and ran into the WINS setting issue.

I've had the same arguments, even when vendors come in and use their own tools to gather performance stats. Managers argue that the vendors skew their results to sell more disk. That's why I have worked hard on understanding who, what, where, when and how to capture and analyze performance statistics on my own (and write about it here). It's hard to argue with the raw data.... 15k disks are not always the answer, but don't go buying a solution without asking questions and preparing with some good data!

I argued with my now ex-boss about why 20 7200 speed disks were worse then 20 15k or even 10k disks.. and he still said ahh they wont see any issues.. some people are just dumb.. Now had the SAN solution been for file storage I would have said no problem with using 7200K speed disks.. But this was for VMs, which included Exchange, Sql and oracle! Still my boss insisted it wouldn't matter..

This only installs the PowerPath/VE modules. The licensing, activation, and configuration is all done using the rpowermt CLI, and the vCLI or vMA to manage claim rules and the like. A bit of scripting could probably be used to automate changing settings on existing datastores or adding new datastores if needed. Josh David – That is correct.
