sql server clustering : How to 'share drive', SCSI HD's on servers
I am not using a SAN to setup Win2003 CLusters, two nodes.
How can I share the hard disk in order to make this work for both nodes ? All documentation I read states that I must have shared hard disk common to the two servers and that's not clear to me when all I have is that hard drive on the respective servers.
You can use SCSI disks. Just make sure whatever you get is on the catalog:

Rodney is correct, your SAN or DAS solution must be in the
Windows Catalog for use on a cluster, but it's more than just getting disks. How you carve them up is just as important, because, for example, if you create one LUN but plan to put multiple drives on it, that won't work.
I am sorry for my lack of understanding here, but let's say if I have two
"regular" Compaq ML370, can I just add two more disks on each server and let's say create a Raid1 and use that as the 'quorum' ? I've seen the list of devices Rod listed OK, but I still don't understand how to configure the disks on my servers to be used in a cluster (assume they are part of the MS HCL).

(...) Actually it is what I didn't understand: From the text below I had the impresson that "external disk storage unit connected to all computers" I still can't see how my regular SCSI disks existing on both Compaq servers can be configured as shared disks. It also says that the controller cannot be the one used by the system drive... Shared Disk Requirements: · An HCL-approved external disk storage unit connected to all computers. This will be used as the clustered shared disk. Some type of a hardware redundant array of independent disks (RAID) is recommended. · All shared disks, including the quorum disk, must be physically attached to a shared bus. Note: The requirement above does not hold true for Majority Node Set (MNS) clusters, which are not covered in this guide. · Shared disks must be on a different controller then the one used by the system drive.

Marlon,
I am considering writing an entire book on disk=20 architecture/design for SQL Server, but I would also=20 suggest you look at the stuff I have in the existing SQL=20 2K HA book to understand what goes into making a cluster. At a minimum, you need (presented at the OS level) for=20 your cluster: * 1 quorum disk * 1 for SQL Server (probably more; I'd say a minimum of=20 two for data and log, but it will depend on your=20 requirements) * 1 for MS DTC (for W2K3 required, and recommended for W2K) Each of these should reside on different physical LUNs on=20 an external drive array, whether DAS or SAN (*not* NAS. =20 The quorum LUN must not be on a disk with any other (many=20 find it a waste of space, but that's the way it is). Some=20 vendors allow you to carve up one chunk of disk, and then=20 do partitions, and that is not really what you should do. Hope this helps.

Marlon, you have all the facts already. You need to buy or use an external
storage, on a different controller.
