PV220 - New disks and adding to cluster

Hi there,
 
I've got 2 PE 2650s attached to a PV220s and clustered on windows 2000 advanced server.
 
We recently had the requirement to add more storage so I added 6 new 300GB drives to the empty slots in the PV220s. I then created the virtual disk within the Perc 4/DC bios and initialised. When the node booted, it recognised the drive which I went through the wizard to create a disk signature/dynamic disk and assign a letter/format.
 
All that worked fine, and I can write to the disk, but when I go to cluster administrator and try and add the Physical disk, the drive does not appear on the drop down menu.
 
I have rescanned to Perc 4/DC's in both nodes and they both see the virtual disk under the array group, but the node that was not used to build the array does not show the virtual disk under the "Disk" section. I'm not sure if that is usual. Please see the linked screen shot.
 
 
Thanks for any help

A few notes come to mind:
- make sure the other cluster node is powered down (good practice (possibly a requirement) when adding a physical disk resource)
- GPT cannot be used in a cluster setup (Microsoft has a patch you can install to allow GPT on a cluster, but it's a better practice to just stay with MBR virtual drives)

Dynamic disks are not supported with clustering, did you format the disks dynamic?

You might take a look at these docs:  Dell Cluster I&T Guide and Microsoft KB Article

Ah that will be the problem then! I assume you can't change it back without trashing the disk and recreating as basic? If so I'll have to back up all the data and restore.

You might be able to find some software tools that can convert, but Windows' native tools indeed will require deleting all volumes (and the data on them obviously) and then reverting back to basic disk.

OK I backed up the disk and recreated at a basic disk. I've still got the same problem though. Any futher ideas?
 
thanks
