Poweredge R610 Raid 5 configuration
Hello to all,
I have one Poweredge R610 with an Storage MD 1000 configured with Raid 5.
I'm starting to make some tests before place the file server live and now i'm having one doubt.
I have 6 disks on the storage and first i create only a Raid 5 of the first 5 disks and the 6 disk as hot spare. Make all the tests and the Hot Spare works well after i deactivate one disk.
Now i place the 6 disk as a total space storage and reconfigure the Raid 5 for 6 disks, i use Dell Open Manage Server Administration to do this, and the Raid 5 of all 6 disks was sucefully done.
But i have one problem here, on WIndows 2003 i'm seeing the disk with the old Raid-5 space (of 5 disks) and i'm unable to expand to the new size. On Computer Management, i can't add volume or make something more. Only delete Volume or Fortmat the disk. But i don't want this because in the future if i want to add a new disk i don't want to loose all the data inside.
Is there any way to do this now? it was me on the configuration that make something wrong?
Thanks in advanced and best regards,
Nuno

I think the first step may be solved with the info in this Microsoft KB article.
One note is that if you grow a virtual disk over 2TB (2048GB), the disk has to have a different partition table; GUID Partition Table (GPT). You can only convert to this if the disk is blank (no partitions at all).
A GPT disk can also not be a boot disk in your setup (Windows 2003); a GPT bootdisk would require you to go into the R610's bios, change it to UEFI and then install 2008 x64 or later (cannot install 2008 x64 and then change to UEFI; you have to change to UEFI and then install 2008 x64 fresh).

You also need to initialize the new RAID volume, this is like a low level format, if you do not do this the data created and written to disk when you were working with the 5 disk volume (i.e.: OS partition size) is still there and taken at face value.
Init you RAID volume (fast init is good enough) and the refresh on Windows disk manager. That will clear all your old data . . .

You either need to use the installation utility (Systems Build and Update Utility - SBUU DVD or Systems Management Tools and Documentation - SMTD DVD), which will load needed drivers AND allow you to configure your first RAID array, OR
You need to configure and initialize the RAID array in CTRL-R before booting to the Windows DVD, where you will then need to load the driver for whichever RAID controller is in your system and for whichever operating system you are installing.
You can put 3 drives in a RAID 5, then have a single-disk RAID 0, but you would need to go into CTRL-R and tell the controller to boot off of the RAID 0 in the event that the RAID 5 failed (or "if ther are no other disck").
