After command line Hosts felt down because half duplex mode of hipervisor

For long time my co-workers added vlan into C7000 Enclousure by graphic interface.
We have cluster but didn't work because virtual connect accept only 162 vlan per interface.
The real problem was when I access Virtual Connect Manager via SSH to configure Vlans.
Blades that limit Vlans was full (162) we receive "failed to add vlan" by console.
But for some reason all over blades those were on limit downlinks felt down of blades.
Looking for interfaces of ESXi was half duplex, and Virtual Connect doesn't work in this mode so that reason the host felt down.
My question is:
First, it is possible the command line to add Vlan and enable smartlink cause half duplex mode in hypervisor?
Second, in command line if don't add speed=auto which speed will be default?
Thanks guys!

c3000 mixing VC and non-VC - Not in adjacent bays

Hi,

 

I have found two setup and installation guides that are more or less the same:

http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c04731477-1.pdf

http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-a00018702en_us-1.pdf

and they are not conclusive (page 15) on the following re supported configurations:

In a C3000, can I I have two VC Flex-10 modules in Bay 1 and Bay 2, and have two non-VC (i.e. GBE2c switches) in Bay 3 and bay 4 at the same time? I know I cannot mix in Bay 1/2 or Bay 3/4.

 

One of the PDFs says that both for a C3000 or a C7000 "*"Other" indicates any VC interconnect module for c-Class BladeSystem".

The other PDF says that this is only true for a C3000 and that for a C7000 "In the following tables, "Other" indicates any c-Class interconnect module including a VC, Pass-Thru, or switch"

Anyone has a config running with VC modules in Interconnect Bay 1 and 2 and non-VC in Bay 3 and 4?

 

Thanks,

Ruben

SSL certificates supporting multiple IPs and names (SAN)

After struggling to get basic SAN-style certificates for the Onboard Administrator, but eventually succeeding, I've now moved onto trying to sort out SSL certificates for our VC modules.

However, it appears that the CSR the VC modules produce do NOT invlude the alternative names, even though they are defined in the web page.

The resulting certificates do not contain Alternative Names in them, so the web browser still complains.

My chassis are running with OA firmware 4.85 and all VC modules (I have a mixture of Ethernet and SAN) have all been updated to firmware 4.63.

I can only imagine this is a bug, but a pretty serious one!

Thoughts?

FlexFabric 10/24 connected to Procurve 5406zl

Hi there have a C7000 with a pair of flex fabric VC 10/24 units, each has a SFP-RJ45 units that are connected to a 1G port on the 5406zl switch. In the HP virtual connect Manager it is correctly showing me which port on the 5406zl the SFP module is patched to. I am taking this as a sign that the switch and the VC are passing information correctly. However, I cant get the BL460 servers to communicate with the wider network over the SUS I have created that contains the SFP links. The server profile contains the SUS  and I can see a pair of 533 NIC's in the Windows operating system that are connected to an "unidentified network".   Any suggestions on what to check or where to start troubleshooting would be absolutely AWESOME at this point.

HPE BLc VC FlexFabric-20/40 F8 Module and HPE BLc VC FlexFabric-10 STACKING Option.

What is the drawaback or cons of Staking 2 Differnet versions os vritual Connect? In our case we have a 2 Blade Chassis with "HPE BLc VC FlexFabric-10 STACKED already" implementation, we are planning to include 1 more blade chassis with but this time we have a "HPE BLc VC FlexFabric-20/40 F8 Module"  different from our setup.

Question:

1. What is the drawaback or cons of Staking 2 Differnet versions os vritual Connect? 

2. Does stacking HPE BLc VC FlexFabric-10 with HPE BLc VC FlexFabric-20/40 F8 Module possible?

HPE Virtual Connect Config Issues

March 5, 2019, 7:36 am

So I have a new HPE C7000 G3 enclosure and I am having issues with getting the networks connections right. Below is the equipment I am using.

 

  • HPE C7000 G3 enclosure

    • 2xHP VC FlexFabric 10Gb/24-port Modules

    • 6x HPE BL460c Gen10

      • HP FlexFabric 20Gb 2-port 650FLB Adapter

      • Windows Server 2016

      • No virtual servers or ESX hosts.

 

There is a 10G Fiber connection going from VC1 and VC2 to different Cisco Nexus 5K switches. The port configuration is setup for trunk mode with a port channel.

 

On the virtual connect side, I have 2 shared uplink sets created. One for each 10G connection. SUS_1 is using the VC1 10G fiber and SUS_2 is using the VC2 10G fiber. On each SUS, I have the VLANs tagged that are also configured on the switch side with the trunk config. I also have smart link enabled.

 

Now for the server profiles, I have Port 1 using the SUS_1 Ethernet network and Port 2 using the SUS_2 Ethernet network. I then assign the server profile to the correct server bay. Port speed type is preferred.

 

Now this is where my problem occurs, I have Windows Server 2016 installed and when I test configured the network connection on NIC1, I cannot reach out to our network. No traffic comes in either. But when I setup a NIC team like I want to do, it starts working. Below is the NIC Teaming settings. So since I have port channel setup on the switch side, do I always require a NIC team on the OS?

While the NIC team is up, and I disable the NIC1 to simulate a failure, the connection moves to NIC2 but no input or output happens and it stops pinging. Is there something wrong with my configuration?

 

Teaming Mode: Switch Indepedent

Load Balancing mode: Dynamic

Standby Adapter: NIC2

 

The reason we require a port-channel on the switch is due to our standards provided by the network team. 

The standard is to have any end point (servers) connected to our network devices with 2 NICs being set up with a teaming (Windows world) / bonding (Unix world) on the server side and Port-Channel (PC) or Virtual PC (vPC) on the network end with LACP.

This is to avoid any MAC flapping as it’s mentioning onto the screenshot that you attached into your email.
A MAC flapping is a problem that could break down our network, therefore to avoid this issue we need to follow our standard defined worldwide.

c3000 FlexFabric 10/24 to StorageWorks 8/24 FC SAN Switch

Hi,

I'm having problems trying to connect a FlexFabric 10/24 to a StorageWorks 8/24 FC SAN switch.

In VC I've setup a SAN fabric and server profile to include ports X1 & X3 on the back of the  10/24 and connected these with 8Gb FC SFP's to the FC SAN.

Ports on the FC SAN are set to NPIV enabled (but show as F-Port in the the status) , and I have option 3 set for that bug (even though my VC and SAN switch firmware are up-to-date).

I can see the WWN's on the SAN switch for the 10/24 ports fine, but I can't see any WWN's coming through for the servers that I have the profile attached to.  In fact, these are showing as NOT-LOGGED-IN on the server (SAN Fabric shows both ports up and LOGGED-IN).

Server that I'm working with is a BL680c G7 with the NC553i card in it (which, by my understanding, should work fine), with VMware ESXi 6.5 installed.

FlexFabric 10/24 is installed in Interconnect 1.  Blade is in Bay 4.  Mapping seems to show correctly when I view it.

Happy to provide any more info required.

 

Thanks.

Problem with 560flb and FlexFabric 10Gb/24-Port Modules

April 10, 2019, 5:27 am

Hi, I have a problem that Virtual Connect won't seem to split up my 560FLB nics into multiple nics. Perhaps I am missing something really stupid here.

To replace our previous C7000 chassis with gen8 blades, we now have a new C7000 chassis with BL460c gen10 blades and 2 VC FlexFabric 10Gb/24-Port Modules. Each blade has a HP Ethernet 10Gb 2-port 560FLB Adapter. Fiber channel uplinks to the SAN and Ethernet uplinks are configured correctly. But when I create a server profile with 2 ethernet connections and 2 fcoe hba connections, only the first two network adapters are mapped.
 
The mappings:
LOM1:1 => Bay 1:d1
LOM1:2 => Bay 2:d1
The FCoE HBA connections are not mapped, and of course I get a warning that not all connections are mapped.
 
What I would expect, is that VC would automatically configure the NICs on the blades to split up. If I look on the old blades (that have the 650FLB adapters) I see that the nics are split up into LOM1:1-a, LOM1:1-b, etc, and all ports are mapped:
LOM1:1-a => Bay 1:d1:v1
LOM1:2-a => Bay 2:d1:v1
LOM1:1-b => Bay 1:d1:v2
LOM1:2-b => Bay 2:d1:v2

How can I get my 560FLB's to split up correctly?

Blade not connecting out to local network

I've inheritted a blade chassis (c7000 with BL660c blades) from a different group, and the configs were not wiped before it was handed over. I was able to wipe the overall chassis configs, but the VC modules still have all their previous configs. I've been able to kinda work around it, but its a pain in the @$$.

The issue I'm having is that the NIC in my VC module (module bay 1) won't see the network. I"ve got ESXi installed on Blade 1 and when I try testing the mgmt network config I've input it fails every time. When I check the ports in VC Manager it says that X1 and X2 are linked/active and linked/standby respectively, but under Connected To it lists "Unknown( )".

I've checked the cabling and it is correct. The switch doesn't have some crazy vlan configured. I have no clue why the enet on this VC module won't see the network.

 

Any ideas?

Problems assigning multiple networks in server profile

I have successfully defined shared uplink sets and ethernet networks for two VLANS and have applied them to a server profile. I'm using VLAN tagging and am able to assign the Network Name expicitly to the appropriate port identified by MAC address. 

Assigning either ethernet network by name in the server profile works as expected, but when assigning both networks using the Multiple Networks option, neither network functions. 

I've seen the multiple networks function work in the past, but for some reason I'm getting stuck on this host. Can someone help me debug this?

Therefore need to manually keyin username and password. Before, it working fine. Its just happen after change of Administrator password and add another user as admin. Is there missing steps that I need to follow on VCM? or should be VCM sync password with OA management?

First steps at Enclosure c3000

Hello, everyone!

Not long ago we've bought c3000 BladeSystem with two BL460c Gen8 Servers on board and two 6125G/XG switches, also we want to buy 3 more BL460c Gen10.

Question is how to connect this farm to our SAN-fabric based on Brocade 300 switches (8 GB Fiber Channel)?

As I understand, after reading tonns of documentation and forums, we need Fiber-Channel Pass-Through module or Virual Connect Fiber Channel Module.

So, can you advice, what exactly modules for Enclosure c300 do I need? Do I need specified adapters for BL460c (at Gen8 we have HPE FlexFabric 10Gb 2-port 534FLB Adapter)? This project isn't cheap for our company and we don't have rights for mistake

Thanks for helping!

Unable to get LACP to work with the HP VC Flex-10 Enet Module and Cisco Nexus 7k switches

July 15, 2019, 10:57 am

Hello All,

My networking team wants to move from the current Cisco Nexus 5k switches to the Cisco nexus 7K switches and want me to move to the 10Gb cables from my 2 Bays on my C7000 chassis 

Right now I have X1 and X2 connected to from Bay1 and X1 and X2 connected from Bay2 to my 5k switches in LACP mode.

Now what I have noticed is that when I move the first 2 cables from Bay 1 i.e X1 and X2 to the Cisco 7k switch and the networking guys make that in a trunk with LACP enabled, one of my links is in active mode and the second one goes in Stand by!

If I switch it back to the old 5K switch, it goes back to being Active/Active again. Now they have confirmed that they are making the LACP the right way but still no luck.

I even tried to move 2 ports from my Bay2 (X1 and X2) and I encounter the same issue, so I had to move it back to the 5K switch.

I mean LACP is configured and working on 5k, so I don't understand why its breaking when moving to 7K switches.

Also if there a setting I need to make sure it's enabled on the virtual connect side when it comes to LACP? I can check that if someone can point me in the right direction.

I have SmartLink enabled for the networks for connection to these 2 bays.

Thanks

Virtual Connect Latency to EMC SAN

We've been having high disk latency between C7000 Blade enclosures hosting BL460c to EMC SAN using hardware iSCSI within Virtual Connect on VMware ESXi.  This appears to be an issue on 6.0, 6.5, and 6.7 so we've eliminated VMware as the problem.  Latency goes away between DL360 and EMC, seems isolated to CClass using Virtual Connect.  Wondering if anyone has seen this or has ideas how to fix it?
