P4300 G2 node upgrade failed

[MichaelGruber]

We have a 4 node P4300 G2 SAN with 3 of the nodes running Software Version 11.5.00.0673.0 but one of the nodes somehow failed during the upgrade process and is stuck at 10.5.00.0149.0.  Everytime I try to "Check for Upgrades", I get an error connectiong to the FTP server.  If I select Use Local Media, the whole process crashes due to the follow message:  The storage system "10.1.3.100" running a manager has disconnected.  The management group TCP connection timed out after 60 seconds.  You will be logged out.

Aside from running a recovery on the one node, is there any other way of upgrading the software on this?  Thanks!

Used the following post - http://community.hpe.com/t5/HPE-StoreVirtual-Storage/Upgrade-from-9-5-00-to-12-5-00-HP-Lefthand-P4500G2/td-p/6849859?_sm_au_=irVWfJsWNTtFJVJN - to manually upgrade single system, though still could not upgrade to 11.5.  Had to bypass and go directly to 12.5.  Odd behaviour.
