I am relitively new in the VM world.  I have created a template with using Windows 2003 Standard with a 25 gig partition.  My ESX servers are attached to a SAN.   I needed to add 2 additonal drives.  When I add the drives this is the step I take.

Add _Hard Disk

Create a new virtual disk

Specify a database store  (I choose my LUN here)

My questions come at this point.  Does each disk need its own SCSI Virtual device node.  But default it uses SCSI (0:1), but when I created the other 2 I used SCSI (0:2) and (0:3)

Does this hurt anything?  What is the pros and cons of this?

Any and all help is appreciated.

It is a good idea to create a separate hard disk for each volume.  It especially helps when you're backing up vmdk(s) and need to restore.  If you have one vmdk with multiple volumes you lose the capability to restore just the system or data drive.  Each hard disk needs a separate scsi virtual device node, just remember you can only have 4 primary partitions, if you need more make one of the vmds an extended partition
