Solved: UCS: Can't reach ESXi server after install on UCS B230 M2 Blade - Page 2

Luke Akpor · ‎03-29-2013

Hi,

I installed ESXi 5.1.0 on UCS B230 M2 Blade, after IP address Configuration then appears the below:

"Download tools to manage this host from

But i can't ping this IP Address and I can't reach it by http.

I use the same IP address as KVM IP pool, I can ping KVM IP addresses.

I plugged and configured management ports only on UCS Fabric interconnect; and uplink ports looks ok. I can ping the SP management and the Server IP addresses from anywhere on the network, but cant ping the ESXi IP address which resides in the same subnet.

I guess I am missing something but can’t really work this out?

Can someone please assist?

Thanks

Thanks Edgar,

Appreciate your response.

Do you have any link as to the different ways this can be setup?

Also when you say "Another way of setting it up would be to not set the native vlan on the vnics in each service profile and tag the vlans on the ESXi hosts by specifying a vlan for each Port Group you create (ie. vmotion, iscsi, vm traffic etc.)"

What then happens to the Mgmt VLAN (VLAN 10 in this case)? I guess I will have to tagged it on the ESXi as well?

Sorry if I am asking too many questions, but just need to get it clear from someone like you with experience on this.

Setting up vMWare and UCS is all new to me so kind of struggling

Thanks once again.

Hi Luke,

I was having the same problem you were having. It was a VLAN issue although my native VLAN and MGMT Vlan were different. My upstream core swith was also not root so it was blocking the port channel for the Mgmt VLAN traffic from the N5K to the network.

I was using Windows in Fusion on my MAC and had issues with F1, F2, F11 etc.. switched to straight windows and was able to get into the command line etc..

Here's the doc I used and it's working great now after some help from Dmitri and Ivan.

http://www.cisco.com/en/US/docs/unified_computing/ucs/UCS_CVDs/flexpod_50_M3.pdf This is 200 pages of a flexpod deployment, so you probably won't need it all unless you decide to set it up this way, but it's good for reference for UCS, N5K, Fabric Interconnects, Vsphere and N1KV.

Hi All, thanks for response.

Just thought I share what the issue was eventually after raising a TAC case.

Anyway following trobleshooting with TAC, there is a known issue with duplicate mac address with vMware which was causing the issue I had.

Once the vmknic was deleted using the ESXi Shell and re-created, the mac address changed from the Cisco range I had of 00:25:B5 to 00:50:56 which belongs to vMware.

After this changed the issue was resolved.

Here is the link to the vMware known issue incase it helps someone else.
