Fibre Channel frames - UCS
I was wondering if it really is possible to have the Fibre Channel frames running on a UCS?
I read these two articles that provide some great information on the implementation of the Fiber Channel Jumbo and Jumbo frames:
http://datacenteroverlords.com/2013/04/01/Jumbo-FC-frames/
http://www.ccierants.com/2013/10/CCIE-DC-definitive-Jumbo-frames.html
Everything in the SAN I'm administration has the ability to set the MTU value until 9036 except for the UCS. For example on NetApp train I can set the MTU by interface on the Cisco MDS I can set the MTU by vsan. However in the UCS Manager when I go to class of service of system quality, the option to set the MTU of Fibre Channel value is grayed out and it doesn't look like there is in any case override the preset frame size. I can set the MTU of the best Effort however my understanding is traffic Fibre Channel in the UCS will use the class system of Fibre Channel.
Also I noticed that I can set the maximum size of the data on the vHBA field in the UCS Manager but my understanding is the maximum that can be up to 2048.
Hello
Have you checked
http://datacenteroverlords.com/2013/04/01/Jumbo-FC-frames/
April fool! I wish I saw this earlier, I would have posted corroborating results!
In short: Forget the CF frames!

Implementation of storage fibre channel (ESXi 4.1) with jumbo frames
I'm looking for 'official' instructions for the activation of the jumbo on a host ESXi 4.1 with storage fibre channel frames. I don't know if the instructions are different, or if anything else needs to be adjusted according to your storage space.
I looked at the instructions from this page here and it seems simple enough. It also seems that you can keep your groups of existing ports rather than having to delete and then recreate. If these good enough instructions apply it for the side host?
I saw this page for iSCSI storage so that made me think if the procedure differs according to the storage.
Wasisnt wrote:
What is the reason for having to recreate them?
If you are in 4.1 that you don't need to recreate anything, just activate via the CLI.
And you can enable frames on a standard port group or is it just for VMkernel port groups?
You can turn on the VM and vmkernel exchanges. Together you must also make the "virtual cards", i.e.: on the Vmkernel virtual network cards and cards of virtual network in the guest operating systems. On the Windows 2003 server, I think you have to use VMXNET3, but on Windows 2008 the e1000 should support frames too.
As has been noted before just make sure that any layer two devices in the path is configured to allow the large frames. You can use this to confirm both Vmkernel and invited: http://rickardnobel.se/archives/992

Uplink Ports Fibre Channel - UCS GUI Configuration Guide
Hi all
Could someone please explain which means that what follows in the Configuration of GUI of UCS guide @.
Uplink Ports Fibre Channel
Manage ports Uplink Fiber Channel FCoE traffic between the interconnection of fabric and the next layer of the
SAN storage network. All FCoE network-related traffic is pinned to one of these ports.
By default, the Fibre Channel ports are uplink. However, you can configure them to work as Fibre Channel
storage ports. This is useful in cases where a Cisco UCS requires a connection to a DAS storage
Device (DAS).
My question is, how the FC Port could handle FCoE traffic? My understanding was that FCoE will be lifted and Enthernet connection only.
Thanks for your help
Concerning
Vikas Srivastava
The CF module interconnection fabric is the place where the speration of CF vs. FCoE happen, so it's where the FC frame is extracted in the Ethernet frame.

Emulator of the UCS and Fibre Channel (PCI Passthrough)
Hello
I would like to know if anyone of you knows if emulator UCS supports CF communications and how to configure them.
I have 2 PCI Fibre Channel interfaces on the host Hardware and I applied PCI Passthrough on the ESXi hypervisor. It works with other virtual machines.
Thank you very much
Francesco
No, unfortunately not.

I would like help on activation and configuration of a Fibre Channel port on 2 of my fabric UCS of interconnections. An external storage device will be connected to those ports.
Hi Mark,
If I'm not mistaken you what you ask, it's you want FC ports on 2 of your FI UCS, which will be connected to a storage device (storage of direct connection) (fabric of interconnection--> storage array).
An excellent guide on how to implement is below.

4.1 and vCenter ESX only allows to use 1 Fibre Channel LUNS
Hello
I have 8 blades ESX 4.1 (build 348481) in a Cisco UCS 5108 chassis. Each blade has 2 x HBAs available. I also have a fiber channel storage array that is configured to provide 2 1.8 to LUN (for now and in the future).
When I go in vCenter and select one of the ESX servers under "Configuration"-> "Storage adapters"-> "Rescan all...» "each server detects the table (and several paths towards it) but only shows a single available LUNS (LUN 0) when 2 LUNS should be available (LUNS 0 and 1 logical unit number). See the image below.
Now, the thing that confuses me is that when I get on the command-line of the ESX via SSH server and run "esxcfg-mpath - b", I see a list of all the paths including the paths to the LUNS 0 and 1 logical unit number (see output below). Any ideas on why ESX and vCenter authorizes me to LUN 1?

It was a problem with that code, that it resembles yours-based Solaris beginning according to the tables and other tables that used code based on Solaris pre-COMSTAR, as well as tables that use SCWIST.
There is really nothing you can do about it, because it is a bug in the software of the array (it shouldn't be exporting 2 LUNS different with the same ID value of Page 83 - it is a violation of the standard).

Problem with XServe and XServe RAID via Fibre Channel
Hello everyone,
I have a problem with my blended Xserve RAID.
I see in RAID-Admin and configure it successfully (via Ethernet). Connect with our Xserve via Fibre Channel, but the XServe and XServe RAID do not detect each other.
The fiber on the Xserve channel LEDs are white on the Xserve RAID completely off and permanent.
RAID-Admin status of Fibre Channel: 'No connection (1 table)' with a red square.
If I try to open the utility of fiber channel I get the message: "card Fibre Channel is not found." Utility disk OS X can't, too.
I changed the card connector cable, and made several reboots. But each time the same thing: they do not detect each other.
Xserve (2009):
-2.26 GHz Quad-Core Intel Xeon 5500
-Map of Apple dual-channel 4 Gb Fibre Channel (LSI7204EP)
XServe RAID:
-RAID 5 in an array (only on the left with 5 x 500 GB)
-1.5.1 Firmware
-Cable Apple 4 Gb SFP - SFP
Thanks for your help and sorry for my bad English!
Hi Mpm-Mainz,
Check if you have enabled LUN masking. To be able to see, you will need to download raid admin 1.5 not the 1.5.1
Have you also tried to use the other controller? Even if there is no disc in there, then it should appear in the preferences of fiber card system.
Thank you

Setting port channel between UCS - FI and MDS 9124 (Mode F)
Dear team,
We tried to create the channel of port between UCS FI and MDS 9124
But the port channel do not take action in mode F on MDS 9124
FI is in host FC end Mode
We have allowed FC uplink on FI trunking
We have activated NPIV on MDS
We have activated the MDS trunk
FI and MDS in default VSAN
To check that we have changed the way FI FC channels mode and switch port became active, but in E mode
When we enabled CF trunking of uplink on the port mode FI channels and FC Switching became active in mode TE
but in both cases above, showflogi database shows WWPN of SAN alone does not have the any fi.
How to achieve this?
Have read that no need to change the mode switching mode of CF swicthing and keep FC Endhost way
SO how to channel ports with mode F MDS and FI (Display Mode as NProxy)
What is it has nothing to do with the MDS NX - OS version? (https://supportforums.cisco.com/thread/2179129)
If yes how to put as license for ports came with the camera and we don't have any CAP/PAK or license file as she came
with license
Also, we saw 2 files available for download (m9100-s2ek9-kickstart - mz.5.2.8 .bin and m9100-s2ek9 - mz.5.2.8 .bin b b) to use
Thanks and greetings

Hi Jo Bo.
What version of the software if your MDS race?
On your UCS do connect nxos and show ficelleStringString ficelleT inteface and find the mac address.
It is possible that you could be hitting the bug below. If this is the case, you may need to update the firmware on your MDS.
Add MAC YES '002a6a', '8c604f', '00defb' for 5 k/UCS-FI

Can I disable the B200 blade Fibre Channel vHBA
Hello
I'm setting up my service to my B200 blades profiles and I was wondering if there was a way to disable the Fibre Channel HBA. I will not use CF as all my iSCSI storage.
Thank you
LTA
When you create a service profile, you are asked if you want the storage (= CF) or not; you say no!
If you missed this step and you have created vhba, just remove them later.
It is not possible to disable vhna.

Fibre Channel card configuration on the host esx 5.1
Hi all,
I have three 5.1 esxi hosts. I have new port 2 8G Fibre Channel cards installed in each and pass the cable FC since the card port goes to the fiber.
It's my first time in collaboration with CF cards VMware hosts, what else should I do for these cards to be active or updated network in? A good explanation, Docs and or video would be extremely welcomed.
Just ask EMC technology to make the zoning on the SAN switch and the LUN masking and card introduced volumes to your hosts on the side storage... after the volumes, simply go to your ESXi, rescan your HBA and create data warehouses.

vCenter 5.5 cluster using Fibre Channel &; MSCS (Win 2003)
Hi all
I need to create a Cluster of 2003 of Windows (MSCS) as well as storage Fibre Channel shared on vCenter Server 5.5. I need to work so that if a server crashes, the second server goes into action and support.
I have a two-node Windows 2003 R2 64 bit running on the same host. Virtual machines are created with an operating system installed. I use for Fibre Channel storage and I have created and attached 6 discs in thick eager set to zero. I also created and configured two NICs (Public and private) on each node. The shared SCSI Bus is set to "Virtual" on both nodes. I managed to get the two nodes to market and both can see the 6 disks. The disk configuration is identical between nodes. All drive letters to even the SCSI virtual peripheral nodes (1:X).
I have not yet created the Windows cluster. The problem is that, in node 1 when I create a folder in one of the attached disks, I don't see this folder in the same drive in node 2. Is it a problem, a bad configuration or is this a normal behavior?
Are there any other setup that I should consider to make this work?
It's the doc that I follow:
Thanks much for any help!
Since you not yet configured the cluster, this is normal behavior. Go ahead and configure the cluster, then the software cluster will manage the discs... do what you try can cause data corruption.
And after the configuration of the cluster, take in mind that the drive will be online to a single node by time, as the Microsoft cluster is an active/passive cluster, in this way you will be able to see the disc and online with the letter assigned only on the active node.
