SRX-node0 ---- SRX-node1
due to upgrade switch0,I need to failover srx primary from node0 to node1
I have one question here
1:only need to failover data plane of srx,right?
2:if I leave control plane primary in node0,dataplane primary in node1,is it fine?
will it cause any issue?
Make sure that all Data RG group expect RG0 (if you have mored that 1 Data RG ) groups they should failover that node 1.
From my point of view looking at this topology it should not be the issue if we failover the data RG say RG1 failover to node 1 and control RG RG0 at node0.
one more question,in which scenario we need to failover control plane
1. If you have configured intf or ip monitoring right, failure / upgrd of switch-0 will result in RG1 (data plane) shifted to node-1 automatically. However, you can do manual shiftover too.
2. RG0 (control plane) cannot shift to node-1 automatically, so you will have to shift RG0 to node1 `manually
request chassis cluster failover redundancy-group 0 node 1
Deepak is also right, there is no issue if you do not do this failover manual (i.e. RG0 at node0 and RG1 at node1) ; only fabric link may be choked.
Recommended is you keep all RGs primary at node1 manually.
1:I don't want to failover RG-0 because it will cause around 10 seconds blip
I 'd like to know why fabric link may be choked if RG-0 in node 0 and RG-1 in node 1
2:in which case I need to failover RG-0,I can't see this possiblity
when external box,switch in our case,is down,RG-1 failover to node 1 and keep working
why should I failover RG-0 mannually
would u like to show me a sceario I have to failover RG-0
thanks in advance
