Hi
I have a problem with a installation in three blades HP BL460. This is the hardware:
• 1 C3000.
• 3 BL460 with four nics.
• 2 Ethernet Switches Gbe2c
• 1 Cisco Switch.
The Nics Vmnic0 and Vmnic1 are connected to first Gbe2c. Vmnic2 and Vmnic3 are connected to the second Gbe2c. I attach a graphic.
I have created a Vswitch for the Vm Network with the Nics:
• Vmnic0 - Active
• Vmnic1 – Active
• Vmnic2 – Passive
Test 1: If in Gbe2c I disable the ports Vmnic0 and Vmnic1, the communication change to Vmnic2. Great.
Test 2: If I disable the links between the Gbe2c and Cisco, the communication is lost,it does not change to Vmnic2
Test 3: If I change the configuration to:
• Vmnic0 - Active
• Vmnic2 – Passive
When cutting the links between the first Gbe2c and Cisco, changes correctly to Vmnic2.
How I can set the Vmnic0 and Vmnic1 in active mode and change correctly to Vmnic2 in case of failure?
Best regards
Hi,
In your test 2, I am guessing that when you disable the links between Gbe2c and Cisco, the esx still sees vmnic0 and vmnic1 as up. This you can confirm by esxcfg-nics -l and hence the failover is not happening to vmnic2, however, you will lose the connectivity, since the service console is vmnic0 and vmnic1
In Test 3, wat is the condition of vmnic1 and vmnic3?
Also, you might wanna look at becon probing for your query.
Thanks,
Selva
Hi Selva
In Test2 the Vmnic0 and Vmnic2 still up, but when I break the links, It not be able to see the gateway or das ip and should switch to vmnic2
In Test 3 the vmnic1 and vmnic3 is not assigned to any vswitch.
The problem only occurs when I have two Vmnics in active mode.
I try beacon probing with same results.
Thanks
Hi,
I am wondering about the results of test 3, Ideally, in test 3, the network should not switch to vmnic2, when the link is brought down between Gbe2c1 and Cisco Switch. I am saying this because, if you have configured Policy as "Link Status Only" vmnic0 is still shown as UP.
I will post my findings, however, could you help me in posting the following outputs:
1. esxcfg-vswitch -l
2. esxcfg-vswif -l
3. esxcfg-nics -l
4. The network policy that you have set during this exercise.
this would greatly help me.
Thanks,
Selva
