I added a HP brocade switch to my fabric.  It is running FOS 6.2.0 and my principles are running FOS 5.2.0.  The new edge switch is showing up as segmented in the left hand GUI.  The OS's are suppose to be compatible.  I cleared the configuration many times on the edge.  I also disabled QOS.  When I pull  up the port on the principle switch it doesn't indicate segmented.  The event log shows no errors.  Do I need to clear out a log so this switch will no longer show up as segmented?  I found a command, fabstateclear, that I thought sounded applicable but I need to make sure it is non-disruptive.  No support from EMC since I'm running an unsupported FOS.  It's end of fiscal year and I'm not upgrading.  Any help would be appreciated.
