SUMMARY
When I try to add second node to a two node cluster I get this message:
"0x00138f Cluster resource not found"

SETUP
Windows 2003 64-bit R2 // HP Proliant DL380 G4 cluster with MGSA 500 G2
storage // Smart Start 7.4

QUESTION
I get the classic error from this Article (909968). I know the the
workaround says 'Don't worry'  but I don't have a complex SAN as they
suggest, it's only a simple cluster.
I took care on not having both nodes seeing the external array until I was
ready to add second node to newly created cluster.
I have checked 'Disk Management' prior to creating the cluster; the BUS /
LUN and TID were identical, despite this, the document blames the error
message on the LUN and TID being different.

What am I doing wrong? Will this cause a problem in the future when I use
this in mission critical environments.
