I've a need to create a couple of new uplink sets for FC connectivity to a new fabric so won't be making any changes to any existing networks or uplink sets. However, I believe that when the Logical interconnects are updated from the LIG the entire configuration is re-applied?&nbsp;</P><P>The version of OV is 5.5. Is there sufficient risk here of the configuration failing to apply properly that it's recommended to do this kind of work out of hours?</P><P>I've done this a couple of times in the past without issue but don't want to push my luck too far...... <LI-EMOJI id="lia_monkey-face" title=":monkey_face:"></LI-EMOJI></P><P>kind regards</P> Fri, 02 Jul 2021 06:43:31 GMT https://community.hpe.com/t5/hpe-synergy/updating-logical-interconnects/m-p/7141333#M759 jlangmead 2021-07-02T06:43:31Z https://community.hpe.com/t5/hpe-synergy/updating-logical-interconnects/m-p/7141388#M761 <P>The correct process to make any changes to uplink sets is to edit them to the LIG &amp; then perform an 'update from group' from the LI.<BR />If any changes are made to the existing uplink sets, there will be momentary outage while the settings are edited on the Virtual Connect interconnect modules.<BR />If no changes are done to the existing uplink sets, then ideally there shouldn't be any outage.
