[j-nsp] Breaking an EX cluster?

[Kevin Wormington]

Are these units all running the same version of JunOS?  If the lab units 
have a new version or vice-versa it could spell trouble.  I ran into a 
similar issue with 4300's and zeroing them and upgrading JunOS to the 
latest recommend version with no VCP modules/cables installed and then 
forming the chassis one unit at a time did the trick.

Right now it’s a stack of 2 and I’d like to make this 4.  The existing 2 member chassis boots fine, all the VCP ports show adjacency and all is good in the hood.:)

I’m using the built in 40G ports and juniper cables that I obtained from Juniper for the back plain wiring on the stack.  No matter what I try I can’t get physical link between the two existing member chassis and one of my proposed repurposed members or member 3 in this case.  (line card roll)

So it’s adding the new to an existing that’s the problem.  Could be process and a very real possibility it’s the guy behind the keyboard writing this that’s the problem but not getting physical link was pointing me at hardware problems.  I just wanted to make sure I cleaned out the previous configs from the proposed new member well enough to not cause it to fail to join.

I know about the factory default button on the front and the configuration option but no matter how I apply that I still have the node boot thinking it’s a member of the previous chassis.  How do I delete it’s membership when it’s active / a stand alone node?
