Drive letter and mount points before cluster creation

-

scenario:
win2k8r2 failover cluster 2 nodes.

storage available san.
witness: mns share on file server

i'm creating sql 2008 r2 cluster uses mount points.

is nessesary following before can create cluster , add disks:

node 1: bring disk online in disk management
node 1: ensure disk has appropriate drive letter, , can access disk/files
node 1: bring disk offline in disk management

node 2: bring disk online in disk management
node 2: ensure disk has appropriate drive letter, , can access disk/files
node 2: bring disk offline in disk management

i'm told if don't ensure disk has appropriate drive letter , mount points before add cluster, can trouble.

the disk(s)  must formatted (ntfs).  drive letters since clustering pick them , make them available across cluster.

you need bring disk(s) online on 1 node formatting.  not matter node.  can change drive letters , mount points on node , information propagates clusterwide. 

under windows 2003/2003r2, mountpoints had done on individual node basis.  windows 2008/2008r2 moved mountpoint data cluster registry persistent across nodes.
