GPT disks gscanga 12/10/2008 11:32:01 PM I'm running a 2-node 2003 SP2 MSCS and have a need to start using GPT disks to accomadate the >2Tb limitation. I saw that there was a hotfix to allow this on systems running MSCS but, other than that, are there any other constraints? I played around with this and presented two lun's to one of the nodes and saw that the option within Disk Manager 'convert to GPT' was grayed out. Additionally, the diskpart command 'convert gpt ' returned an error. Perhaps the error will disappear after the hotfix is applied? Or is there something else I'm missing.

Re: GPT disks "Robert Smit" <Robert.smit-nospam-aca-computers.nl> 12/11/2008 11:38:22 AM Hi gscanga, With your Windows 2003 SP2 you can not use dynamic disks,spanned volumes. basic disks are supported. and if you want to change a disk you can oly change it with diskpart. There is a KB that maybe usefull. http://support.microsoft.com/kb/947711 -- Greetings, Robert Smit Blog : http://fiberman.spaces.live.com/ "gscanga" <gscanga[ at ]discussions.microsoft.com> schreef in bericht news:0685DD71-A80B-4940-AFDE-7ACEFEF8DE51[ at ]microsoft.com...

Re: GPT disks "John Toner [MVP]" <jtoner[ at ]DIE.SPAM.DIE.mvps.org> 12/12/2008 11:05:03 PM I agree with Edwin here...specifically, you must ensure that there are no existing partitions on the drive before "converting" from MBR to GPT. You cannot convert an existing MBR partition to a GPT partition...you can only convert an empty disk to GPT Regards, John Visit my blog: http://msmvps.com/blogs/jtoner "Edwin vMierlo [MVP]" <EdwinvMierlo[ at ]discussions.microsoft.com> wrote in message news:egNb9rDXJHA.4632[ at ]TK2MSFTNGP04.phx.gbl...
