Connecting Fabric Interconnects together with FC
Hi,
Is it possible to link two Fabric Interconnects together with FC uplinks?
If I have two sites and I have a pair of Fabric Interconnects in site A and a pair in site B. Is it possible to connect FI-A of site A to FI-A in site B via an FC upllink port? Or should I use a Cisco MDS or Brocade switch to make the connection?
In each site we have a server with FC connections and they need access the storage on the other side. Is it possible if I place the FI in FC switching mode?
Kind regards,
Gert
Hi Robert,
Thanks for the answer. On each site there is only one server with FC connections, so it's a high cost to buy MDS switches only for that. Is it possible to connect them via FC or should we really buy some FC switches. It's only for 1 server per site...
Thanks in advance and regards,
Gert

Connecting Fabric Interconnect with MDS
Dear Team,
Kindly share how to configure connectivity between Fabric Interconnect and MDS
what are the steps to be followed in establishing a successful connection between FI and MDS
We have a tape library from IBM and trying to connect the same to FI via MDS and want this Tape library to be detected on the guest VM running windows 2008 on Esxi( Service profile with 2 vhba already added),we are trying using Fibre connectivity.
Also please advice in which mode should we keep the FI (FC switching,end host etc)
Thanks and Regards
JoseHi Jose,
The common steps to configure FC on FI and MDS as following :
1. FI configured in NPV mode, ensure that all FC uplinks and vHBA of Blades have been assigned on correct VSAN
Verify if vHBA Flogi into the FI
show npv flogi-table
show npv status
Example
FI-A(nxos)# sh npv flogi-table
SERVER EXTERNAL
INTERFACE VSAN FCID PORT NAME NODE NAME INTERFACE
vfc703 10 0x330001 20:00:00:cc:1e:dc:01:0a 20:00:00:25:b5:00:00:03 San-po102
vfc711 10 0x330002 20:00:00:cc:1e:dc:02:0a 20:00:00:25:b5:00:00:02 San-po102
Total number of flogi = 2.
FI-A(nxos)# sh npv status
npiv is enabled
disruptive load balancing is disabled
External Interfaces:
====================
Interface: san-port-channel 102, State: Up
VSAN: 10, State: Up, FCID: 0x330000
Number of External Interfaces: 1
Server Interfaces:
==================
Interface: vfc703, VSAN: 10, State: Up
Interface: vfc711, VSAN: 10, State: Up
Number of Server Interfaces: 2
2. Enable NPIV mode on MDS, configure the link to FI as F port. Assign this port into correct VSAN
FI will become Node proxy, so verify if all vHBA have been detect on Upstream NPIV switch
SW2(config)# sh npiv status
NPIV is enabled
SW2(config)# sh flogi database
INTERFACE VSAN FCID PORT NAME NODE NAME
San-po102 10 0x330000 24:66:00:2a:6a:05:e9:00 20:0a:00:2a:6a:05:e9:01
San-po102 10 0x330001 20:00:00:cc:1e:dc:01:0a 20:00:00:25:b5:00:00:03
[BLADE1-SAN-A]
San-po102 10 0x330002 20:00:00:cc:1e:dc:02:0a 20:00:00:25:b5:00:00:02
[BLADE2-SAN-A]
3. Configure zoning on the MDS (to make sure whether the issue on zoning or not, you can configure the default zone to permit)
Example : zone default-zone permit vsan 1
Verify the zoning on Upstream NPIV switch
SW2(config)# SH ZONESet active vsan 10
zoneset name ZONESET-VSAN10 vsan 10
zone name INE-VSAN10 vsan 10
* fcid 0x330001 [device-alias BLADE1-SAN-A]
* fcid 0x330002 [device-alias BLADE2-SAN-A]
* fcid 0x2a0000 [device-alias FC-SAN10]
4. Ensure that vHBA of BLADE had been discovered on the storage device. Configure LUN masking on the storage
I really don't have enough knowledge of VMware hahaha.....so can't help for troubleshooting the VM....Really sorry
Thanks,

Connecting Fabric Interconnect to iSCSI array
I need to connect my Fabric Interconnect to a new iSCSI array. There are a number of UCS blades that need to connect to iSCSI LUNs. The FI is currently connected to the rest of the network through Nexus 7000K switches. Should I connected directly from the FI to the iSCSI array, or go through the 7000K and then to the array?
Hi
this is more of a design question, you have to think what will need access to the ISCCI storage array. For example, if only UCS blaes will have access to this storage array, you may want to consider connecting it directly as iscsi traffic won't have to go through your N7Ks if both fabrics are active.
If you want another type of server such as HP or IBM to access the storage you may want to consider connecting the storage array to the N7Ks if your fabric are configured in end-host-mode. Again this will depend on your current implementation -
Use UCS Fabric Interconnect 6100 with Extension Module E0060 (6 FC Ports)
Hi Everybody,
I have problem in my Architecture !!! I THINK
I want to use Extension Module E0060 (6 FC Ports) for UCS Fabric Interconnect 6100 for interconnectiong my Storage Array ( 2 Controlers with 2 FC Ports by cont.) instead of use Nexus 5000 between FI 6100 and my Storage Array
I tried to find details or case study for this way but No thing find !!!!!!!!!!!!
I just find that th e best practices is to use Nexus 5000 but I have enough FC Ports with this Module ...... I THINK but I m not an Expert
Thanks for your help.Thanks for your answer Michael,
But I really don't understand why I can't use the Module E0060 (6 FC Ports) in the FI 61xx instead of NEXUS 500 (I hope that's not commercial goal ) ????
As you now the hardware architecture of FI 61xx is the same that Nexus 5000, the difference is that 61xx have features added and UCS Manager embedded.
Now, If they have a features limited in 61xx like NPV or other things, I wil understand But until this moment I don't find Real ANswer in Cisco site of forum ( Al cisco documents mentionned that the best practices and the perfect design is to use 61xx and Nexus 5000 and MDS Switch between UCS and Storage Array ???????
I Hope that you understand my problem -
6200 Fabric Interconnect licensing with 2232 FEX
I have searched and searched but can't find the document to answer this. I know that every port on a 6248 or 6296 needs to be licensed to work whether it's Ethernet, FC, or FCoE.
We know it's supported and we want to connect a pair of 2232PP FEX up to our 6200 FI for C-series server connectivity.
When connecting a 2232PP FEX up to a 6200 FI, there are a potential of 8 uplink ports from the FEX to the FI. Do all 8 of those ports need to be licensed to work? Do any of the new 32 ports that show up once the FEX is connected need to be licensed as well?
Thanks!
ChrisHello Chris,
The ports on FI connecting to FEX ( Server ports ) needs to have licenses. The ports on FEX connecting to hosts ( rack servers - backplane ports ) is not counted for licenses.
You can use all of those back plane ports without worrying about licenses.

Appliance port on 6248 Fabric Interconnects
Is it possible to setup a storage device with a CIFS share on the 6248's through a port defined as an appliance port? The GUI guide says this:
"Appliance ports are only used to connect fabric interconnects to directly attached NFS storage."
But what would be the difference if it were a CIFS share rather than an NFS mount?
I'm trying to setup a storage unit that does both NFS and CIFS, but the backup software that I want to point to it through the FI's needs to have it as a CIFS share due to being a Windows platform.
Any and all comments welcome.
Thanks,
ChadiSCSI, CIFS and NFS targets are all valid uses for the appliance port.
All the appliance port does is allow MAC learning on the interface.

Fabric Interconnect 6248 & 5548 Connectivity on 4G SFP with FC
Hi,
Recently I came across a scenario when I connected a 4G SFP on Expansion Module of 6248 Fabric Interconnect at one end and at other end 4G SFP on 5548UP. I was unable to establish FC connectivity between both of the devices and the momemt I connected 4G SFP on Fixed Module of 6248 connectivity got established between both the devices
I would like to know do I have to do any changes on FI's Expansion module to get the connectivity working or this kind of behivor is expected behavior
Do let me know if you need any other information on this
Regards,
Amit VyasYes, On FI-B port 15-16 should be in VSAN 101 instead of 100, I have made that correction
Q. are you migrating the fc ports from the fixed to the expansion module ?
A: As off now I am not migrating FC port but in near future I have to migrate FC ports to Expansion module and I don't want to waste my time for troubleshooting at that time.
Is my understanding correct, that you have 2 links from each FI to a 5548, no port fc port-channel ?
A: Yes, your understanding is correct we have 2 links from each FI to 5548 and no FC port-channel is configured
I will do the FC port-channel later on once I am able to fix the connectivity issue
I will try to put 4G SFP on expansion module and will provide you output of "show interface brife"
Following is the out of "show interface brife" from both 5548UP switches

I have a macbook air (mid 2012) and a thunderbolt display (27'').
Do I absolutely need to connect the power supply together with the thunderbolt cable ?
I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,

Port-channel L2 problem with Fabric Interconnect and Nexus 7010
Hi,
i using port-channel from both fabric interconnect to N7k with 3 cables per Fabric Interconnect.
but, my problem is when i creating port-channel, Fabric Interconnect don't support mode ON dan rate-mode share in Interface 10G Nexus 7010.
I was trying :
1. I using non dedicated port in Nexus 7010.
- rate-mode share
- channel-group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was suspended
2. I using non dedicated port in Nexus 7010
- rate-mode share
- channel group 1 mode on
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was came up, but in Fabric interconnect was failed.
3. I using dedicated port in Nexus 7010
- rate-mode share
- channel group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was suspended
4. I using dedicated port in Nexus 7010
- rate-mode dedicated
- channel group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was came up and running well.
but, the problem is my costumer do not want using a dedicated rate-mode. if i using dedicated mode the only available port is 8 interfaces instead of 32 ports. i want to using rate-mode share in nexus 7010.
is there any way to configuring port-channel using mode on in fabric interconnect ? i was trying using CLI to create port-channel in Fabric interconect but i cannot configure the channel group protocol.
i attach the topology of N7K with Fabric interconnect.
regards,
Berwin HHi Manish,
the issue was solved, i was fix it last week.
the solution is:
i enable the license grace-priode (since my license is Enterprise so cannot create VDC) then i create a VDC (ex: VDC 2) so i allocate the interface on all module

N7K-M132XP-12 to VDC 2. after that i delete VDC 2 then all interface back to VDC 1 (default vdc). then i enable the rate-mode share in dedicated port and bundle into port-channel and its working.
i dont know why it must move to VDC first then it will working, maybe cisco can explain the reasons.
So here the result of my port-channel :

Is there a way to see SAN luns from the UCS fabric interconnect.
Hello,
I have recently added a 3rd and 4th vHBA to a B440 running RHEL5.
Originally I had 2 vHBAs', and each created a path to 172 luns. (I was multipathed to 172 luns)
Now I have added two additional vHBA's and my SAN admin assures me he has mapped, zoned and masked all 172 luns to the 2 new vHBA's.
So, at this time I should have 4 paths to 172 luns....but I don't.
What I see is 4 paths to 71 luns.
I still see 2 paths to all 172 luns, but only see 4 paths on 71 of them.
Its almost like my SAN admin either mapped or masked only 71 of the 172 luns to my 3rd and 4th path.
Via the RHEL5 OS I have rescaned the FC paths, rebooted, done lsscsi, looked in the lowest level places for what devices are present on my FC channels, always I see 172 devices on the 2 original FC paths and 71 devices on the 2 new FC paths.
My question is....is there a way to see all devices (luns) accociated with an vHBA from the command line in the Fabric Interconnect?
My configuration is UCS w 2 FI's, using 8Gb FC connections to Cisco 9500 directors, to an EMC DMX4.
Thanks in advance,
Genewdey,
The link you supplied in your response is the answer.
You can look at the devices on the FC boot paths, but not while the OS is running.
I have a test server I could reeboot to try what you have in your document, and it does work.
Too bad Cisco could not create a linux util rpm that would allow looking down the fabric while running. Im quit sure emulex has this kind of util, called HBAanywhere...at least for solaris.
In any case, thanks for the link to your article, it was VERY good!
My problem with seeing a shorter list of luns on 2 of my FC paths may get solved this afternoon by a change my SAN admin is going to make.. If it does I will post the fix. -
Hi all,
its any issue to get a fabric interconnect cluster connected to a 6504??
becuase we are reviewing to get a connection betwen this 2 devices without any nexus devices.... is any problem with that??Hello ,
Yes, you can connect UCS FI to 6500 switch.
Make sure you configure STP port fast on the 6K switch ports connecting to FI ( if operating in End host mode ).

UCS-Fabric Interconnect Replacement
Hello everybody,
I have a UCS domain with a failed Fabric Interconnect and i have to replace this Fabric. For me there is no action to do in the configuration of the new FI i just have to add it in the existing domain and give it the IP address, but i have a question about the firmware version. is the firmware automatically installing in the new Fabric or have i to install it manually ? the firmware version in my domain is 2.2(1b).
Thanks for the answer
Best Regards
François FiocreHi Claudio
I assume you talk about 10G copper, not 1G copper;
and if 10G: CX-4 (Twinax) cables, or 10G Base-T ?
There is a 12-port 10GBASE-T module, but this is only supported on the Nexus 5596T so of no use on Nexus 5596UP switch, nor UCS FI.
Anyway, it is a not recommended to connect UCS FI Uplinks to a Nexus 22xx ? just think about the oversubscription ! you would like to have as much bandwidth Northbound as possible. -
Fabric Interconnect and storage solutions
Dear
Please I would like to clarify a question, is that a solution of storage, such as EMC VNX5300 can be connected directly to a Fabric Interconnect, but would lose functionality when connected to a Nexus 5000 switch. I would like someone to clarify this doubt indicating that functionality is lost when direct connection would be advisable to FI or the Nexus.
RegardsIn versions of UCS earlier than 2.1, you had the option to useDirect Attached Storage DAS with UCS. However, you needed a SAN switch connected to the FI so the switch could push the zone database to the FI. That is, the UCS platform was not able to build a zone database
With the release of Version 2.1, UCS now has the ability to build its own zone database. You can have DAS with UCS without the need for a SAN switch to push the zoning configuration
hope this helps -
Cisco UCS 6200 Fabric InterConnects Needed?
Currently looking to put Cisco UCS 5100 blades into our datacenter. Our core currently has a 7K with F2 48-Port blades with FCOE licenses. We currently have our ESXi servers terminating directly to the 7K for both 10G Ethernet and storage via FCOE. If we decide to replace our standalone rackmount servers with UCS blades, can we connect the blade chassis directly to the 7K, or are the 6200 fabric interconnects required? If so, what purpose do they serve. Thanks.
Yes, fabric interconnect is required for a UCS blade solution; it can aggregate a maximum of 20 chassis a 8 blades, or a total of 160 blades.
On the fabric interconnect runs UCS manager as a application, which allows you to do firmware management for the server farm (bios, I/O adaptor, CIMC,....); the concept of service profiles implements server abstraction and mobility across hardware. -
my iphone 4 doesnt want to start . all it shows is the apple icon.i have tried holding the home button together with the lock button. nothing seems to work . please help.
Plug the iPhone in with the Wall Charger. Then while plugged in do the Reset again, hold both Home and Power buttons until the iPhone Restarts. This usually begins to happen in less than 20 seconds time.
