Virtual connect 1/10Gb and C7000

Hi Guys,

 

I'm trying to get my virtual connect module to see two NICs that are on Mezz card 1 (BL460c G6) and map through to device bays 3 and 5. I know they are mapped through because I can see the MAC addresses from within VC Manager device bay screen. The problem I have is (unlike the two onboard NICs) I can't map the NICs to ethernet networks within VC.

 

When I try to add an addtional NIC from within server profiles I see

Allocated bandwidth  - Not allocated

MAC - HP Predefined

Mapping - Not mapped

 

You can see from the attached that the first two are fine. Its the second two that refuse to map

 

Does anyone know why I can't use these NICs from within VC Manager?

 

Thanks in advance

Re: Virtual connect 1/10Gb and C7000

Hello,

 

please tell us more from your Bladechassis infrastructure.

 

How many Virtual Connect Moduls have you in your Chassis and in which Bays?

If you have only 2 in Bays 1 + 2 then it is not possible to get more ethernet connections for your Blade.

 

For mezzanine cards on socket Mezz 1 you need the Interconnect Bays 3 + 4 populated with the necessary Moduls.

In your case 2 additional Virtual Connect 1/10Gb Moduls.

 

Please look in the pdf on page 18. You can see the physical mapping of the onboard and Mezzanine cards there.

Re: Virtual connect 1/10Gb and C7000

Hi Thomas,

 

I've got four virtual connect 1/10Gb modules sitting in bays 1,2,3 and 4

 

A dual port NIc on Mezz card 1. I would expect to see two onboard ports coming through to module 1 and 2 and the two addtional coming through on modules 3 and 4 ( I have other BL460 G6's in the chassis with quad ports NICs. Two of these come through on modules 3 and 4)

 

Is it firmware or a case of having to create a new profile for the blade in question? Any help greatly appreciated

 

Thanks

The LOM connections are on ports 1/2, Mezz  1 goes to ports 3/4. To use all ports of a Quad port card, use Mezz 2 as it connects to 5/6 and 7/8

Re: Virtual connect 1/10Gb and C7000

Hi Jim,

Thanks

Re: Virtual connect 1/10Gb and C7000

Hello,

 

the BL460G6 Blade uses Dual-Port Flex10 Nics. This NIC can be deviced in 4 logical NICs. If you use only VC 1/10 then you dont use this technology.

Please try to create more NICs in your Serverprofile. Create 10 NICs in your Profile. 8 NICs are for the 2 Flex NICs (logical) and the last 2 are for the Mezzanine Card. Use the first two NICs as you shown in your picture. Leave NICs 3 - 8 unassigned. NICs 9 + 10 should be connected to the VC Moduls in Bay 3 + 4.

VC_Server_Profile091015.PNGHi Thomas,

 

thanks for getting back. If I create 10 NICs within the server profile I see the above. I don't receive the MAC or mapping like I do for the first two NICs. Is there another setting that needs to be configured before I try the above?

 

Thanks again

Re: Virtual connect 1/10Gb and C7000

Hello Simon,

 

so my idea to create more NICs was not successfull. The onboard NIC shows only LOM:1 and 2.

 

If other servers are working fine with the four VC1/10 Moduls then we have some problems with the mezzanine Slot of the blades or the mezzanine card itselfs.

Please show me a profil from the working blades.

Can you tell me the Model or the Partnumber of the Dualport NICs?

Please check the mezzanine sockets (Blade and card) carefully. Sometimes there is a damaged contact.

Have you used the same mezzanine Slot on all Blades?

 

Can you move the non-working blades to another Device Bay? Perhaps the device bays have a problem with the contacts on the Midplane.

Have you switched the device bays from a working blade with a non-working blade?

Re: Virtual connect 1/10Gb and C7000

Thanks for getting back Thomas

 

This is a profile for a working blade. This blade has a quad port NIC on Mezz 1. You can see that I am using the two LOM ports and one of the quad port NICs. If I attempt to add a fourth NIC I receive the same. Its as if there needs to be some added configuration before I can use additional NIC ports

 

VC_Server_Profile141015.PNG

 

Model of dual port NIC is NC373m Dual Port Multifunction 1Gb NIC for c-Class BladeSystem

 

I've used the same mezz slot on the other blades allbeit they have a quad port NIC

 

I can try moving the blade into another slot when next back onsite

 

The original blade in that devce slot was used to replace a faulty blade in another slot. The blade now in slot 9 is a replacement from warranty

 

I believe it to be a config setting that I need to carry out before the addtional NICs can be used.

 

Thanks again

Re: Virtual connect 1/10Gb and C7000

Hello Simon,

 

for the fourth port it looks like we have a problem with the VC Modul in Interconnect Bay 4. Please check the port mapping from OA of the chassis. You can select a blade on the left side.

First select the blade. Choose the second tab (Information) in the middle. Check the nics.

Second select "Port mapping" of this blade on the left. Then you can see which NIC port is mapped to the internal ports of the VC Modul. Onboard to Bay1/2, Mezz Slot1 to Bay3/4.

 

Check the port mapping on the Interconnect Bays within the OA.

 

Check that all 4 VC Moduls are up and running.

Check this in VCM (Virtual Connect Manager), under Hardware you can see "Overview". There must be 4 moduls in the first two rows.

Select the "Interconncet Bays" on the left side. You see in the middle all VC Moduls of the chassis. Select each modul, then you got more Informations about the modul (General Information, Uplink Ports, Server Ports ...). You have to look for the server ports. There you can see which nic of the VC modul is connected to which server nic port (LOM, Mezz 1, Mezz2).

Post some screenshots from the mapppings from OA and VCM.

Re: Virtual connect 1/10Gb and C7000

Hi Thomas,

 

The NICs and port mappings look to be fine

 

VC_Port_Mappings.PNG

 

Both VC Modules in bays 3 and 4 are powered on and not showing any warning signs

 

VC_Module_4.PNGVC_Module_3.PNG

 

We can see from the below that other Blades are connected to the VC module in bay 4, but not Blade in device bay 9. Although the Blade in bay nine is displayed the status shows as not linked. I can't help think that there is a check box or setting that needs to be enabled

Re: Virtual connect 1/10Gb and C7000

Just had to power-down the blade, delete the associated profile, create a new one, apply it and power-on the server

Thanks for peoples help

Re: Virtual connect 1/10Gb and C7000

Ok,

Does this means that everytime we add new VLAN on the network or adding one more uplinks, then HP Blade server must be rebooted to reflect new changes ?
