Well the hot connection of the CX4 cable shouldn't be a problem (this at Hardware level): the question could be instead if the Logical IRF Port should be shutted down before adding (binding) another physical port to it...but, AFAIK, adding more physical ports to an existing Logical IRF Port is a task that does not affect the ongoing traffic on that Logical IRF Port...this to say that, from the Software perspective, the whole addition can be done online without disruption.
The most updated HP 5500 EI & SI IRF Configuration Guide was published back in 2015 and can be found here.
Please note the specified IRF Link Redudancy and IRF Port binding restrictions:
IRF link redundancy
The switch supports up to two physical ports for an IRF port, and these two ports must be located on the same interface card.
IRF port binding restrictions
- Facing the rear panel, make sure the physical ports bound to Logical IRF Port 1 is on the left of the physical ports bound to Logical IRF Port 2.
- Physical ports of an Logical IRF Port must be on the same Interface Card.
Those two latest sentences basically mean that (as I read them), respectively:
- Physical port bound to Logical IRF Port 1 defined on IRF Member 1 needs to be on the left of the Physical Port bound to Logical IRF Port 2 defined on IRF Member 2 (which, if I read your actual IRF configuration's output correctly, is the contrary of what was setup on your IRF) so Physical Port 1/1/1 should be connected to Physical Port 2/1/2 (read: Physical Port n/m/p means n=Switch member, m=slot, p=port); thus considering that each JD360B Interface Card owns two ports, this also would mean that adding a second physical port to each Logical IRF Port need to be done between 2/1/1 and 1/1/2. Clearly this should be valid considering that Logical IRF Port 1 is binded to two ports, Physical Ports 1/1/1 and 1/1/2, and Logical IRF Port 2 is binded to two ports, Physical Ports 2/1/1 and 2/1/2. Note the Slot=1 on both IRF Members's physical ports numbering, just one 2-Ports Interface Card is used (there isn't 1/2/p or 2/2/p). [*]
- Logical IRF Ports should be binded to Physical Ports belonging to the same Interface Cards (as wrote above): this seems to exclude that you can distribute Physical Ports between Interface Cards - another method to avoid SPoF at Interface Cards level by using differents Interface Cards - on the same IRF Member (so no new JD360B is really necessary for the purpose).
At the end the IRF configuration should be like:
MemberID NewID IRF-Port1 IRF-Port2
1 1 Ten-GigabitEthernet1/1/1 disable
Ten-GigabitEthernet1/1/2
2 2 disable Ten-GigabitEthernet2/1/1
Ten-GigabitEthernet2/1/2That's a Daisy Chain IRF Topology with Logical IRF Ports bounds to multiple (two, per Switch) Physical Ports to add resiliency and load balancing to the IRF link.
As a starting point see this HP Support Information (JD368B was used in the example).
[*] I hope that HPE doesn't mean that IRF Port 1 of IRF Member 1 should use Physical Ports of Interface Cards installed on Slot 1 (Left of Slot 2) and IRF Port 2 of IRF Member 2 should use Physical Ports of Interface Card installed on Slot 2 (right of Slot 1)...
