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 Vyas
Yes, 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

Failed:Error disabled - SFP vendor not supported on Fabric Interconnect 6248UP
We are connecting a FC-uplink on a Fabric Interconnect 6248UP to a MDS9124. On the Fabric Interconnect side we use a 8Gbps SFP (DSpSFP-FC8G-SW) on the MDS9124 side there is a 4 Gbps SFP.This should work when speed is at fixed speed 4 Gbps on both sides (I was told). When the SFP's and cabling is connected I get an error in the UCS manager on the FC-uplink port we are using:
Failed:Error disabled - SFP vendor not supported.
I cannot change the speed on the FC-Uplink ( I can only set user-label). The Fabric Interconnect is configured for FC on the last 8 ports and that is where the SFP for the storage is located (port 31).I have a similar problem. I'm using port 1/41 and gets this output

Fabric Interconnect Login types
Hello all,
so im trying to login to my fabric interconnects via SSH and cant login in with the 'Local' Account i have set up OR the Local Admin account on the FI's.
we have our 'Native' Authentication setup for LDAP so that works.
I have tried Admin@local , Admin.local and it doesnt seem to work.
i dont want to have to change the 'Native' or Default Authentication type just to login in with local admin to the FI's.
any help would be appreciated. Thanks.

Port-channel Problem between Fabric Interconnect and N7K vPC
Dear all,
I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
This is my network topology for UCS Deployment
In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
Thanks,
Trung.Thanks Matthew very much,
I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.
Thanks,

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.

Is there any way to reduce theirs RPM? So then can be quieter? The server room have proper air conditioning.

FABRIC-A(nxos)#UPDATE
I opened a TAC, then after several reviews of the LOGs and huge sh tech files, we concluded that all was normal. This loud noise is normal and within in normal operational ranges.
However as the server room is not fully acoustics proof and located near production work desks, we managed to get a RMA for the fan modules for the version 2 modules which are MUCH quieter than V1 due new design.
I have upload both pictures for comparison of the designs.
Thank You! -
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 -
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 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,
GertHi 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 -

I have changed the cables but not luck.
Also I do not have network connectivity yet to my FI's ,I connected L1 to L1 and L2 to L2 ,configure my laptop to same subnet and using one of the mangement console port to access UCS.
When I do a ping test one FI A reponds and FI B does not.Vip which is on FI A also reponds since this is on FI A.
If I move it to FI B.The VIP also would not respond.
any help on this would be appreciated
Thank You

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. -

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 To MDS 9148 FC Port Channel/Trunks
Is it possible to create both a Port Channel and Trunk on a Cisco MDS 9148? Yes correct?
Or can I only trunk between the 2 MDS switches and not the MDS to Fabric Interconnect?
These FC links would be connected to a 2248XP Fabric Interconnect carrying multiple VSANs from the MDS to the Fabric Interconnect.
ThanksHello,
Yes, you can have trunk links grouped into port channel ( F port-channel trunking ) between FI and MDS.

Is it possible to connect both ethernet switch and FC switch from 6120 Fabric Interconnect using the 8 port extended module?
Dhinesh,
Which expansion module are you using? N10-E0440 or N10-E0080 (both of them have eight ports).
If its E0440 - Yes, you can use it for both Ethernet uplink as well as FC uplink.
E0080 - Is just FC ports.
(the ports on the module which have green color on them are FC ports).
Here is the URL to the Spec sheet for your refernce:
