VEM module debugging

[wagde]

Hi

I've installed the VEM and VSM successfully, I added two vNICs (VM-A and VM-B) to the data port group and I'm trying to check connectivity between the VMs.

When I try to ping from a VM_A to VM_B another one I see the following message in the /var/log/vmkernel in the ESX server:

Oct 26 11:35:22 ibm2 vmkernel: 0:16:23:42.388 cpu4:4691)No source_ltl; dropping portID 50331651
Oct 26 11:35:22 ibm2 vmkernel: 0:16:23:42.388 cpu4:4691)n1kv: sf_netif_pkt_sched: No packetlist receive hook

and the ping does not pass!!!

1. What does these messages mean?

2. Can I debug the VEM module from the ESX Service Console?

3. Can I debug it from the VSM?

Thanx

Wagde:

To help us debug this issue, can you run the following commands and post the results here:

1. vem status -v
2. vmware -v
3. If a COS system: cat /proc/vmware/version | grep vmklinux
4. vmkload_mod -l | grep vem

I'm suspecting that perhaps one of our kernel modules is not loaded here due to some versioning error. This will help us debug this if it's the case.

Thanks,

Kyle

Hi Wagde,

Please can you let us know the following:

1. VM-A and VM-B are they on the same VEM.

2. The vlans in  the port-group assigned to the VMs are they allowed on the uplinks connected to upstream switch.

2. Output of "vemcmd show port" and "vemcmd show trunk"

3. Output of "esxcfg-vswitch -l"

Also it would be helpful if you can provide your uplink or PNICs details connected to the upstream switch (vmnic1 and vmnic0) .
