can't convert San volumes into dynmaic disks Benoit 12/30/2008 8:55:01 AM Hi, I'm having troubles to convert San volumes into dynamic disks . I try to convert from basics to dynamics disks (to create a raid1 volume). I use this volumes for windows clusters . but i read that Dynamic disks are not supported for use with Windows Clustering. Can you help me and explain wy i can't convert it with windows 2003 natives tools? ---------------------------------------- DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ---------- ------- ------- --- --- Disk 0 Online 510 MB 0 B Disk 1 Online 210 GB 0 B Disk 2 Online 210 GB 0 B Disk 3 Online 210 GB 0 B Disk 4 Online 210 GB 0 B Disk 5 Online 210 GB 0 B Disk 6 Online 110 GB 0 B Disk 7 Online 68 GB 0 B * Disk 8 Online 10 GB 10 GB DISKPART> select disk 8 Disk 8 is now the selected disk.

Re: can't convert San volumes into dynamic disks Benoit 12/30/2008 3:33:01 PM hi robert, if the disk is already in use as shared disk in a cluster can i use a third product tool to convert the disks or do i need to delete this disk ressource from the cluster before to do someting. Also i don't know if it's a microsoft cluster problem because all my san disks can't be converted into dynamic disks ( compared to the nodes local disks ) ... that's weird i'm going to deactive cluster disk management and see if the the san disks can be converted thanks for your support !!! also the Kb was helpfull: i've read ... "Windows 2000 Advanced Server, Windows 2000 Datacenter Server, Windows Server 2003 Enterprise Edition and Windows Server 2003 Datacenter Edition support only basic shared disks in an environment that uses the Windows Server failover clustering feature. Failover clustering does not provide native in-box support for dynamic disks" thats means but I don't know if it's a microsoft cluster problem because all my san disks can't be converted into dynamic disks ( compared the nodes local disks ) "Robert Smit" wrote: [Quoted Text] > HI Benoit, > > Did you try dskprobe an old resource kit tool. but if the disk is already > published in a cluster you can't convert it any more. > > Checkout the K'b items the are maybe helpfull. > http://support.microsoft.com/kb/237853 > http://support.microsoft.com/kb/816307 > > And do remember san disk needs alignment ! > > Here is a nice link all about the alingment. > > http://kb.wisc.edu/page.php?id=4556 > > http://msexchangeteam.com/archive/2005/08/10/408950.aspx > > > -- > Greetings, > > Robert Smit > Blog : http://fiberman.spaces.live.com/ > > > > > > "Benoit" <Benoit[ at ]discussions.microsoft.com> wrote in message > news:00DF911D-0D77-4D26-B1DB-67DA75FEE3CF[ at ]microsoft.com... > > Hi, > > > > I'm having troubles to convert San volumes into dynamic disks .

You can't convert them, period. Anyway, why should you want to do such a thing? Massimo

Re: can't convert San volumes into dynamic disks Benoit 12/30/2008 6:47:27 PM it's because I need to present a volume for windows clustering This shared disk must come from 2 differents SAN FC datastores ( from 2 differents areas) to provide high availabilty i thought Raid1 with dynamic disks should be the solution to solve the issue "Massimo" wrote: [Quoted Text] > "Benoit" <Benoit[ at ]discussions.microsoft.com> ha scritto nel messaggio > news:65E70778-DBE9-4579-8A5E-003CA00FFCB9[ at ]microsoft.com... > > > also the Kb was helpfull: i've read ...

Re: can't convert San volumes into dynmaic disks "Ryan Sokolowski [MVP]" <ryan[ at ]clustering101.com> 12/30/2008 6:56:15 PM I think you're a little confused about your volume creation. Create your highly available volume using disks within the SAN itself - whether that's a RAID 1, RAID 5 , etc. configuration. Then, when you present the newly created LUN to your cluster nodes, leave the disk alone (as a Basic disk). You can't use a dynamic disk in Server 2003 MSCS Clustering.
