Remove shared disks from cluster

[gjb]

Hi,

We have an EMC CX300 providing storage to 2 MS clusters (W2K3 SP1).We are
planning to delete 1 of the disk groups with 2 LUNS that are currently
presented to cluster 2, re-organise the disks into new LUNS with a different
RAID level and present them to cluster 1. The Dell SAN engineer will take
care of the SAN/Navisphere re-config, but I am unsure how to correctly
remove the disks from the Windows servers. (I have already relocated the
data to new disks on cluster2).
I know I will have to offline and delete the cluster share and physical disk
resources, but do I need to manually delete the partitions and if so which
nodes (A/P) and what order (reboots etc)? .. Or will they just "disappear"
when they are removed from the SAN and the systems re-booted. In that case
will the Server nodes have any remnants of the old disk names/drive letters
etc.that will require cleaning up.?
Apologies if this is a bit rambling :)

TIA

Geejay.

Assuming you already did data migration, as stated in your post:

1) remove all dependencies other resources have on these disks
2) delete the physical disk resource from cluster, using cluster
administrator
3) in disk management delete the drive letter and delete the partittion
4) in Navisphere, remove the LUN's from the storage group
5) ensure that none of the nodes have access to these LUN's anymore
6) if not already done: build the dependancies to the new disks

At this point you can unbind and re-use your disks
(or have the Dell SAN engineer do what ever he has planned)

Rgds,
Edwin.

Is there a MS document that outlines this process from Step 1 to Z? ie,
when/if nodes need to be off line; what services if any need to be stoped (ie
cluster disk service) etc?
