He EE,

We have a PE2850 with PERC 4e.  Last week I added a sixth drive to the exiting RAID 5.  I follow steps found right here on EE and even rebooted the server.  Now Dell OpenManage Server Administrator show the additional drive space on the array, but W2K3 does not.  Disk manager show the unallocated space just like every other post here.  I have seen several posts in my quest for the answer relating to diskpart, and other partition utilities.  I am running a consistency check right now.  Any thoughts as to the safest way to address this.  I have a full backup of all the data, but would realy hate to have to restore it.  NON DATA LOSS would be fantastic.

What you are seeing in disk manager is just what it should be.  Adding the additional drive and extending your array does just the hardware part.  Now Windows sees the unallocated space and you need to either create a new partition or add the space to an existing partition - which sounds like what you want to do.  You can use any number of free or commercial utilities to do this.

You mention diskpart which is supposed to be a good free Linux-based utility.  I've only played around with it a little and it didn't seem to do what I wanted.  One disadvantage is that you have to shut down the server.

I use a commercial program called Paragon Partition Manager Server Addition (must user server edition on server OS's).  If I remember right it only cost about $50 bucks and has been great for me.  I am able to extend / shrink / move partitions on the fly without having (usually) to reboot the server.

Thanks for the help.  further research enabled me to convert the existing partition to dynamic and use disk management to extend the drive.

Ahh ... it's the system partition you need to extend -- DiskPart won't do that.

Easy fix ....

=>  Download the free demo of Boot-It NG [http://www.terabyteunlimited.com/bootit-next-generation.htm ]

=>  Create a bootable CD (or floppy if you have a floppy drive)

=>  Boot the Boot-It CD/floppy --> at the first prompt select CANCEL (you don't want to install it); then OK

=>  Click on Partition Management

=>  Highlight the 2nd partition (the one you want to extend -- you can be sure you've got the right one by noting the size)

=>  Click on ReSize (on the right side of the screen) ... select the maximum size (it will show you what that is); and let it do its "magic"

Done :-)

... Boot-It is a superb little utility that does a lot more than this => it's well worth $35 to have it in your "arsenal" of tools :-)   [But as I just noted, the free demo will do what you need here just fine]
