vdx6720#vcs rbridgeid x vcsid 2 enable
Suggest running the above command on each switch - change x to values 1 to 4.
then check the results of 'show vcs'
If that still does not work, then drop back to 2 units only (as two does not reuire a license for VCS - this is in case there is an issue with the license.

thx for the quick reply. I've just tried that. BTW - I can't use the "enable" keyword because the VCS is already active:
vdx3# vcs rbridge-id 3 vcsid 2 enable

Yep that is what I would next.
disable VCS mode on all boxes. then leave two not connected.
re enable the two that are still connected. Brocade also recommands changing the deafults from VCSID 1 to another number and not to use the rbridgeid of 1.

I've tried that now but without success.
After changing the systems vdx1 and vdx4 to normal switching mode with "no vcs enable" and then re-enable VCS on these 2 systems via "vcs rbridge-id (10|11) vcsid 10 enable" it's still the same. The boxes are connected on ports te20 <-> te24 (1G-TX-SFP) and they are seeing each other through LLDP but no cluster is formed.
I'am a little bit lost in the moment. Any further suggestions would be appreciated.
Otherwise I'am going to contact our distributor or brocade directly to find someone who is able to check the setup/systems (e.g. remotely via a TeamViewer session).

I note in your post you twice mention GE ports rather than 10 GE.
"...The 4 1GE connections are ok"
"...are connected on ports te20 <-> te24 (1G-TX-SFP)"
If in fact you are using 1 GE ports, then I believe a fabric will not form. A VCS fabric requires 10 GE ports.
Can you confirm if you have 10GE port optics? The VDX can be configured with either 1GE or 10GE SFP.

very interesting hint! Because of a lack of LC/LC SMF patchcords I can't use my 10GE-LX SFP+ modules here in the lab and so I've tried all this using 1GE-TX SFP modules. I'am going to obtain some LC/LC SMF patches right now and come back with the result!

I have found some LC/LC MMF patches in the lab and noticed that I have 10GE-SX SFP+ modules as well. So I tried this modules instead of the 1GE-TX ones and it works!
I wasn't aware of the "VCS fabric needs 10GE ISL links" fact until your hint - thank you Brook!

I'm having this issue with a pair of 6710s. As the switches are booting they both say:
We're using 10Gbe twinax with brocade SFPs etc. The clustering comes up ok and the various command output looks alright but show vcs says that it's in local only config mode. Is there such a thing as non-local only config mode? The manuals don't seem to have much detail in this area.
