Cisco ucs 5108 thermal problem

si
Hi everyone!
I've installed my first UCS system: 2 UCS 5108 & 2 UCS 6248
In first chassys six blade-servers (2 - b230 m2& 4 b200 m2). In second - 5 b200 m2. I've got two air conditioners in server room working on their maximum. For the last week i've received three faults on first chassis (Fault Code: F0411). IOM temperature was about 45-46. After that i've mooved 3 blade-servers to second chassis until i solve this problem.
UCSM version - 2.0.2r
Everything is quite good, except thermal problem. All blade-servers discovered, 0 errors and critical.

Sergey,
If this is a real I2C issue, you may still see the same behavior on 2.0.x release if the I2C bus was not cleared before the upgrade. (in this moment I don't know if you recently performed an upgrade on the system or not)
I2C bus tranports information about the different components of the Unified System, this, meaning Chassis, IOMs, Fans, PSU, etc... What happens is that all those components try to send theit status update while other do the same and then the I2C bus gets overwhelmed, and then noone can really report their real status, so we usually recommend the customer ro reseat all major components, one at the time, to clear the bus and then do the upgrade, if that is not done before the upgrade, it still should be done after.
Try reseating the Fans and PSU, one at the time, leaving a minute in between and then, IOMs one at the time, leaving three minutes in between and begining with the subordinate to cause minimun disruption.
If this does not clear the situation, then you will need to remove one of the components already mentioned, one at the time and do a "show tech-support chassis # all brief" to see what the I2C bus reports segment by segment (chassis, Fans, PSUs...) once you remove a component and the errors on each segment stop incrementing you will have your faulty piece of hardware, and a TAC case will be needed to send a replacement.
For further analysis or assistance, I strongly recommend a TAC case to be opened.

Windows 2008 R2 on Cisco UCS B200M networking problems

This is driving me completely nuts. Let me start by saying I am new to blade servers and Cisco UCS. I did take an introduction class, and it seemed straight-forward enough. I have a chassis with two B200M blades, on which I am trying to configure two Windows 2008 R2 servers, which I will eventually make Hyper-V servers. This is all in a test environment, so I can do anything I want to on them.
Right now I have installed W2008 directly on hard disks on the B200M hardware.
The problem is this: even though I think I've configured the network hardware correctly, using the Cisco VIC driver software, I cannot get networking to work in any reliable way. I cannot even get ping to work consistantly. I can ping my local server address, but I cannot ping my gateway (HSRP address). When I try, I get a "Reply from 10.100.1.x: Destination host unreachable (x being each particular server's last octet). I CAN, however, ping the individual IP addresses of the core switches. I can also ping some, but not all, the other devices that share the servers' subnet. There are no errors being generated, the arp tables (for those devices I can ping) look good, netstat looks OK. But I cannot get outside the local subnet...
Except when I can.
There are times when I can get all the way out to the Internet, and I can download patches from Microsoft. When it works, it works as expected. But if I reboot the server, oftentimes networking stops working. Yet another reboot can get things going again. This happens even though I've made no changes to either the UCS configs or the OS.
I cannot figure out any reason when it works at some times and not at others. I've made sure I have a native VLAN set, I've tried pinning to specific ports on the Fabric Interconnects. There is just no rhyme or reason to it.
Anyone know of where I can look? I'm very familiar with Windows on stand-alone boxes (although it's no longer my area of expertise), and I manage a global WAN (BGP, OSPF, Nexus 7k, etc.) so I'm no dummy when it comes to networking, but I am utterly stumped on this one.

The problem was this: while the NICs on the blade server are called vNIC0 and vNIC1, Windows was calling vNIC1 "Local Area Connection" and vNIC0 "Local Area Connection 2". So what I configured on UCS did not match what I was configuring in Windows. Completely, utterly ridiculous.
Anyway, networking is working now without any issues. Thanks for you suggestion; it did get me looking in the right direction.

Cisco UCS Director Login Problem

Hello Community,
I have recently installed Cisco UCS Director 5.1. According to the documentation the initial login requirements are admin for username and admin for password, see image;

However, authentication keeps on failing.
Any ideas?

Problem connecting Broadcom NetXtreme II 57711 to Cisco UCS 6120

Hi all,
I ordered rackmount server(C210 M1) with Broadcom NetXtreme II 57711 which I would like to connect to Cisco UCS 6120 in switching mode, but I can't make it working. Broadcom has 2 slots for SFP/SFP+ so I inserted Cisco SFP 10GBase-SR into it. I also inserted the same SFP into the Cisco 6120.
I also tried to cross the fiber but I still got no link.
I tried to lookup supported SFPs from Broadcom but have no luck so far. Can anybody help, please?
The only technical specification I found is http://www.cdw.com/shop/products/default.aspx?EDC=1997284 . I don't know if it is reliable but I can't make much of it.
Mat

Martin,
Both the 6100 Farbric interconnect and the Broadcom support SFP+, below I have included some supporting documentation.
The first link shows the supported adapters for the C Series Servers (Overview of Cisco C-Series Adapters .pdf) which has a link to a datasheet for the broadcom. The second link provides a list of supported SFPs.
http://www.cisco.com/en/US/prod/ps10265/ps10493/c-series_adapter.html
http://www.cisco.com/en/US/partner/prod/collateral/modules/ps5455/data_sheet_c78-455693.html
The output of show interface brief on the fabric interconnect will display which interfaces have an SFP present, you can also use the command
show interface ethernet x/y transceiver details for more information.
If you still have issues you can use a process of elimination, change the cable, SFPs try a different port on the fabric interconnect. Plug another
supported device into the fabric interconnect to see if it comes up. You can use a similar process to rule in or out a problem with the Server.

Cisco UCS RAID SAS 2008M-8i Mezzanine Card Performance?

I recently purchased a UCS C220 bundle, which includes a Cisco UCS RAID SAS 2008M-8i Mezzanine Card. I'm planning on deploying this as a standalone server running XenServer 6.2 in the near future.
I'm happy with the unit and testing is good, but for one aspect. The disk IO throughput on it seems to be far short of what I expected. I have a desktop PC with an Intel DZ77GA-70K motherboard as a lab spare, and the disk IO I can achieve from that server with the same disks exceeds what the C220 seems to be able to achieve, on a consistent repeatable basis.
The testing I am doing is based around two benchmarks:
1. A 400G file copy between the two machines, over the network back-to-back to note the maximum sustained throughput, and
2. A mix of runs with 'sysbench' to mix of tests of local IO, of sequential and random reads and writes, with the command: "sysbench --test=fileio --file-total-size=150G --file-test-mode=seqrd --init-rng=on --max-time=300 --max-requests=0 run"
For #1, I run a copy to/from an HP MicroServer Gen8, which has 12TB of disk space on it in a Linux RAID0 configuration (4x3TB Seagate drives). If I copy files to or from this HP Server to the Intel DZ77GA-70K I am able to easily saturate the 1G network, achieving a sustained 960MBit/s for an hour or more at a time. If I then take the exact same SATA disks from the DZ77GA-70K, connect these into the UCS box and do the exact same network copy with the exact same OS, I'm only about to get around ~400-500MBit/sec of sustained throughput.
For #2, the test results of which are entirely local to the C220, come in around 105-110 MByte/sec on a sequential read, which drops to around 2 MByte/sec on a random read or write test. No surprise of the enormous drop - because random reads/writes are a pretty tough IO load, but I would expect sequential reading should be much better. I can get consistent sysbench seqrd results from the MicroServer of around 300 MByte/sec, for example.
I can consistently replicate this with Redhat 6.5, as well as Gentoo (running the latest linux kernel) as well as from a Xen 6.2SP1 Hypervisor install on the C220 (tested from the Dom0 domain itself, as well as a Linux guest) all 64 bit. Jumbo frames are enabled end-to-end also, and CPU is not bottlenecking. Latest firmware is installed on all components. The ucs-cxxx-drivers.1.5.4a.iso image states that for the Redhat and Xen systems, that the required drivers are included in the OS, so I don't need to worry about installing them separately. Presumably the Gentoo system has even newer drivers again because it has a very new kernel, but alas the throughputs are the same on all of those systems.
I have tried with SATA as well as a SAS drive, and the test results are also practically the same. All disks in all servers are Seagate 6.0 Gb/s units, and none of the servers are swapping to disk at any stage.
I am happy with network IO - I can completely saturate the 1G ports easily, and I'm convinced that's not a part of the problem here.
What could cause this sort of performance? Storage card logs in CIMC don't indicate anything is wrong and none of the OS's are indicating issues of any sort, but it certainly does seem something isn't right in that I'm getting significantly superior performance from a desktop motherboard and the MicroServer, than an enterprise grade server, when testing with the exact same hard drives.
Questions:
- Is the 2008M-8i card considered a low-end RAID card or should I be getting reasonable throughput from it? I was anticipating performance at least as good as a desktop motherboard, but this doesn't seem to be the case. The RAID card as a component is more expensive than an entire MicroServer or Intel Motherboard so it should run much better, yes?
- What sort of performance should I expect out of this card on a single sequential read or write?
- Can this RAID card run drives just as JBOD's or do all disks have to be initialised in an array (even if just a RAID0 array with 1 disk)? It seems if they are added to the server they do not show up to any OS until they are initialised as part of an array, although I haven't delved into the BIOS settings of the card itself (only from CIMC so far).
- I recall seeing something about best practice of having two virtual drives on these cards, what is the impact in running more, given the card certainly allows more to be created (I currently have 4 while I am testing)
- I noticed on Cacti graphs while rebuilding a RAID1 array that the CPU ran hotter while the array was being rebuilt, and cooled down once the rebuild had completed, which indicates the rebuild was using up CPU on the host hardware. Should this not have been entirely transparent to the system if the RAID activity is offloaded to this card, or is an increase in CPU to be expected?
I'm very keen to find out others experiences of this card, what people have done to get good throughput out of it, or if I should go back to a whitebox server with an Intel board :-)
Thanks,
Reuben

Hello Reuben,
I reached out to colleagues who are more knowledge on this topic and here is their response.
- Is the 2008M-8i card considered a low-end RAID card or should I be getting reasonable throughput from it? I was anticipating performance at least as good as a desktop motherboard, but this doesn't seem to be the case. The RAID card as a component is more expensive than an entire MicroServer or Intel Motherboard so it should run much better, yes? -
2008M-8i card is a entry/value card with an expected performance which is better than a software RAID. This card doesn’t utilise memory in a standard RAID 0/1 configuration.
- What sort of performance should I expect out of this card on a single sequential read or write? - We should expect around 1GB sequential read (refer link http://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/unified-computing/whitepaper_c11-728200.html)
- Can this RAID card run drives just as JBOD's or do all disks have to be initialised in an array (even if just a RAID0 array with 1 disk)? It seems if they are added to the server they do not show up to any OS until they are initialised as part of an array, although I haven't delved into the BIOS settings of the card itself (only from CIMC so far). -
This card can be used in JBOD mode. To enable JBOD mode you need to use MegaCLI commands. This option is not present as a default configuration.
Please note: Once we enable the JBOD mode – it cannot be reverted back to the default RAID mode setting.
- I recall seeing something about best practice of having two virtual drives on these cards, what is the impact in running more, given the card certainly allows more to be created (I currently have 4 while I am testing) -
This doesn’t apply for this card as it does not have any cache. Can you please point us to the document about best practice of having two virtual drives ?
- I noticed on Cacti graphs while rebuilding a RAID1 array that the CPU ran hotter while the array was being rebuilt, and cooled down once the rebuild had completed, which indicates the rebuild was using up CPU on the host hardware. Should this not have been entirely transparent to the system if the RAID activity is offloaded to this card, or is an increase in CPU to be expected? - Creating/Deleting/Modifying a RAID volume is a CPU independent operation.

Cisco UCS C220-M3 Server doesn't boot after adding Intel I350 Quad Port NIC

Hello,
We have purchased 2 Cisco UCS C220-M3 rack mounted servers (Single Processor) that have a dual port I350 LOM. We also purchased two Intel I350 Quad Port NICs to expand the available ports on each server from 2 to 6.
The problem we are facing is that the server will not complete the boot process unless we disable either the LOM or the Quad Port NIC. We have tried numerous settings in the BIOS area but we haven't managed to have them both working.
The I350 Quad Port NICs are from Intel and not from Cisco and we are running the latest FW/BIOS on the Servers as of March 10 2015.
We have followed the steps described in the installation guide to install them.
Could you provide some light in this situation please, what are our options?
P.S. Although the LOMs are I350, the MAC Address Vendor is Cisco, is it possible that Cisco servers accept only Cisco Branded Expansion Cards?
Thank you,
George

Hi Shawn,
At least I'm not the only one having the same problem!
You are trying to use the cards with the LOMs enabled?
Which screen are you referring to in the first paragraph of your message?
Mine sits in BIOS POST for about 10 minutes and then resets itself....
We are also waiting for an answer from Cisco, so any findings/news will be posted here.
Thanks,
George

Cisco UCS Director Foundation (UCSDF) 5.0 Training

Hello Community,
Can anyone help me where i can attend the following Training for (( Cisco UCS Director Foundation (UCSDF) 5.0 )) as i can not find a schedual in CISCO training locator .. It is highly important for me as i have an implementation soon and i need to get its knowledge .
Thanks & Best Regards ,
Mostafa Elgindy

Mostafa,
I think you'll have a little problem getting this running. There is huge interest in this topic but to be fair, Cisco has only just now (the past two weeks) released the 5.0 course materials to the instructors. So far as I know, me and two other instructors are the only instructors in Europe which are both certified to teach this class as well as actually have hands on experience with Director. In addition, we can't as instructors get our hands on the actual product outside of dCloud to actually update our knowledge for v5.0 because of the insanely stupid terms involved.
I have been asked three times so far to deliver this course. I've said no 3 times. I wouldn't even consider it without a few weeks to prepare, so I personally won't deliver it before March. There are some guys who like reading slides that will do it sooner, but you may have issues with getting questions answered.

Ethernet controller driver not installing after Windows Server 2008 installation on Cisco UCS blade

I am using MDT 2010 to deploy Windows Server 2008 to a Cisco UCS B200 blade. The OS and hotfixes install with no problem. The system reboots and attempts to connect to the deployment share to continue with the task sequence and I receive an error stating
"A connection to the deployment share could not be made. The following networking device did not have a driver installed. PCI\VEN_1137&DEV_0043&SUBSYS_00481137&REV_A2"
The driver in question is the driver for the Ethernet controller for the UCS blade. More specifically, it is the network driver for the Palo card in the UCS Chassis. When I Ignore or Abort the install, I am able to manually install the driver and restart the
task sequence. The build then completes successfully with no further issue. I just cannot seem to automate the driver install. Has anyone dealt with this type of issue?

Vik and stealthfield - thank you for your responses.
I was preparing a script to manually move the driver into the c:\windows\inf location when I had to stop to create a new task sequence for a different build. It was while building this task sequence that I found the soulution to the problem.
In the Post Install -> Inject Drivers step of the Task Sequence, I noticed that it was executing a command of type "Inject Drivers" with a selection profile of "All Drivers" and "Install only matching drivers
from the selection profile" selected.
I changed this to run a command of type "Run Command Line" and specified that it execute "%Scriptroot%\ZTIdrivers.wsf". I noticed that this was selected in one of my other builds that was working properly, so I thought I'd
give it a try. - IT WORKED.
So to sum up, the solution was to change the type of command being executed in the "Post Install -> Inject Drivers" step of the task sequence. After this change, the machine came up and continued the task sequence with no further issues.
Thanks again for the responses - They were helpful and I do appreciate it.

FCoE options for Cisco UCS and Compellent SAN

Hi,
We have a Dell Compellent SAN storage with iSCSI and FCoE module in pre-production environment.
It is connected to new Cisco UCS infrastructure (5108 Chassis with 2208IOM + B200 M2 Blades + 6248 Fabric Interconnect) via 10G iSCSI module (FCoE module isn't being used at th is moment).
I reviewed compatibility matrix on interconnect but Compellent (Dell) SAN is only supported on FI NXOS 1.3(1), 1.4(1) without using 6248 and 2208 IOM which is what we have. I'm sure some of you have similar hardware configuration as ours and I'd like to see if there's any supportive Cisco FC/FCoE deployment option for the Compellent. We're pretty tight on budget at this moment so purchasing couple of Nexus 5K switches or something equipvalent for such a small number of chassis (only only have one) is not a preferred option. If additional hardware acquisition is inevitable, what would be the most cost effective solution to be able to support FCoE implementation?
Thank you in advance for your help on this.

Unfortunatly there isn't really one - with direct attach storage there is still the requirement that an upstream MDS/N5k pushes the zoning to it. Without a MDS to push the zoning the system it's recommended for production.
http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.0/b_UCSM_GUI_Configuration_Guide_2_0_chapter_0101.html#concept_05717B723C2746E1A9F6AB3A3FFA2C72
Even if you had a MDS/N5K the 6248/2208's wouldn't support the Compellent SAN - see note 9.
http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix8.pdf
That's not to say that it won't work, it's just that we haven't tested it and don't know what it will do and thus TAC cannot troubleshoot SAN errors on the UCS.
On the plus side iSCSI if setup correctly can be very solid and can give you a great amount of throughput - just make sure to configure the QoS correctly and if you need more throughput then just add some additional links

UCS mac address problem

Hi all,
simple question....
may you know if, with release 1.4.1 there is some mac address learning bug?
i've go a blades with a mix of palo and other cards, some vnic are pinned to uplink with trunk and allowed vlan 501 on both side. On the UCS blades i've got ESX and ESXi. Service console is tagged to VLAN 501 (according to trunk configuration on UCS and uplink switch). Some blade had got these interface pinned on UCS6100 A and other one on B (with failover). The fact is that if i ping from outside UCS to inside UCS (ESX) no mac learning is performed on all infrastructure.
I'm sure problem is on UCS 'cause if i clear mac table on UCS nothing works......and all work if i begin to ping from UCS. I've also tried to put on uplink switch a static mac (ESX service console) but was not useful.
i hope is not a 1.4.1 bug......
tnx and tnx for help
dan

Are any of you using Uplink Pin Groups or have a disjointed Layer 2 network by chance?
Issues like these are ususally related to Pin Groups/Disjoint L2 using the wrong link as the DR port for incoming traffic. When traffic is generated from within UCS outbound, the MAC table gets updated on the upstream switch which allows traffic to flow, until it ages out.
If either of these are the case I suggest you have a look at Brad's videos, name video #6:

Conectar Cisco UCS via Nexus a NFS via IP

Tenemos una solución Cisco UCS la cual esta conectada a los Switches de Agregación Nexus y cuando se trata de conectar un o unos ServidoresVirtuales o SX a un NFS via IP no establece la conexión generando time-out, pero si la solución Cisco UCS es conectada a unos 6500 que se comportan como unas extensiones del Nexus, si se establece la conexión sin problemas.

Si efectivamente tenemos este problema, los UCS conectados a través del Nexus llegan a establecer la conexión a los NFS luego de varios intentos se establece, cuando se hace la consulta de información se vuelve extremadamente lenta , los nexus en nuestra red son los Switches Cabecera de Acceso manejan la capa 3 del Datacenter y se encuentran conectados a ellos 4 Switches 6513 vía vpc como extensiones en capa 2, la conexión de los Fabrics de los UCS conectados tambien via vpc hacia ambos nexus, cuando se tenían conectados los fabrics en los 6500 la conexión hacia los NFS se establecía normalmente, tuvimos que sacar los servidores que requieren este tipo de conexión a unos Blade de IBM que están conectados a los 6500

Cisco UCS VIF path unpinned

Hi,
I have the following scenario, Cisco UCS chassis with 2 Blade B440 placed in slot 5 and 7.
The blade in slot 5 is taking some time but the VIFs get pinned (FI Uplink) after approx 3 min.
as for the server in slot 7 the VIFs using the adapter 2 remains unpinned and even sometimes the "Link State" becomes "Unknown" and after a few seconds it changes to "up" but the "FI Uplink" always remaining unpinned.
Apparently the problem only occurs between the adapter 2 and FI-B
After checking the "IO module 2", I found that the Backplane Port 2/29 is in a failure status.
I changed the server slot from slot 7 to slot 1 and apparently everything was fine.
do you have any suggestions?

Hi,
you are right I have checked the statistics on the FI server port 1/4 and this is the only interface that has
fcs and Rx errors (about 30,000 in 2 days).
I changed the cable but the errors remained.
I even chnaged the IO module, still the same error.
I changed the FI interface to 1/7, I got the same errors on the new interface.
FInally I changed the policy of the IO module to "PortChannel" instead of "None" there is no errors neither on the port channel nor on the interface, this is really weird but after changing the behavior to portchannel, I was unable to reach my servers (neither the ESXI hosat, nor the VMs inside it)
I am really stucked, any suggestions?
