UCS B-Series Fan Module 3 Performance and Temperature N/A

Hi,
I have one UCS-B chasis. In the Fan status, I have one fan module with a weird status:
Operability - Operable
Performance - N/A
Power - On
Temperatura - N/A
I attach printscreen. Any idea what's going on?
Thanks in advance,
Ruben

Hi Padma,
latest version, 2.1.1a.
LED status was green.
We did a HA testing and we took this fan out and then in again. Since then we have this output.
Regards,
Ruben

UCS C series server whether accessible from Linux prompt

Hi UCS Team,
I have UCS c series server.
I am able to check the Fan, power,cooling and equipment and hardware status using the CIMC.
In CIMC I configured the SNMP and check it using MG soft Mib browser tool.
The CIMC query the BIOS for getting the information.
Similarly is there any process to get the BIOS information from the Linux.
Correct me If I am wrong anywhere.
My requirement is to query the UCS C server BIOS information using Linux-SNMP without CIMC.(direct access of BIOS from Linux)
Can I install a Linux supported SNMP client and supported MIBS to query the BIOS level information of UCS using SNMP MG soft Mib browser?

Hi Keny,
I tried to powercycle both servers (c260M2 and C460M2) but still no discovered server and also no logg.
I checked
Rack Server Discovery Policy == immediate
Rack management Connecton Policy == Auto Achnowledged
Chassis/Fex Doscovery Policy == 2 Link and Port-Channel (As I installed 2232PP I moved to Port Channel)
I am running UCSM Version 2.1(1e)
FI 6248 Version 5.0(3)N2(2.11e)
2232PP run on same as FI
I also have a connected 5108 with IOM 2104 running on 2.1(1e) Version.
CIMC Version of C260M2 and C460M2 will be checked tomorrow when my kolleague is in the datacenter.
Server Connection is not really the same like in http://www.cisco.com/en/US/docs/unified_computing/ucs/c-series_integration/ucsm2.1/b_UCSM2-1_C-Integration_chapter_011.html
Because I still have no VIC Card but the connections are the same.
C260 GE LOM1 <-> FEX2 Port 11

UCS C Series hardware monitoring

Does anybody know how we could monitor the UCS C Series hardware (power supply, Hard disk, Memory ect...) within SolarWinds. We usually monitor servers via SNMP. It looks like there is the CISCO-UNIFIED-COMPUTING-EQUIPMENT-MIB that is supported on UCS manager 1.4 and above. When I to poll the box for those MIB's I get the OID is not supported. The UCS C Series server is on 1.3(2j) for the firmware version. Do we need to upgrade to 1.4 to get the equipment monitoring to work or is there another way? I notice a lot of users are monitoring B Series in Solarwinds but I haven't really seen anything on C Series.
Any thoughts would be appreciated.

Hello,
Yes, CIMC 1.4 has additional SNMP functionality.

NI 9853 C Series CAN module Synchronization

OK, this is goning to be long to explain...First of all Im using a CompactRIO 9004 system with 9104 Chassis and the NI9853 high speed CAN module. Ive been able to perform a loopback test between CAN0 and CAN1 ports of the 9853 module (with standard and extendend IDs). I also have a fully functional CAN network consisting of Microchip hardware, specifically two dsPIC30F4011's with the MCP2551 CAN transceiver and one 18f4553 with an MCP2515 CAN controller and a MCP2515 CAN transceiver, this network also works well within itself (I send messages through the CAN network and the PICs are able to control some servos). Im trying to interface the cRIO and NI9853 with this CAN network, but neither the NI9853 module will successfully transmit or recieve from any of the PICs. Funny thing is that I connect everything to the same physical bus (twisted pair cable with 120ohm terminators) and Im still able to transmit from CAN0 to CAN1 of the NI9853, and also the PICs are able to transmit/recieve within themselves. I think it all has to do with sync issues, the thing is; Ive gone as far as programatically writing the BTR0 and BTR1 registers of the NI9853 module (which has a Phillips SJA1000 CAN controller) to match those used by the Microchip hardware, and still no communication. Im trying to transmit at 1Mbit/s, using 20Mhz clocks on my external CAN network, for this Im using 10 time quantas to represent the nominal bit time, from what I understand from both CAN controller datasheets (MCP2515 and SJA1000) the definition of the segments and the sampling point for the bits is what is of importance (as well as the scaler value), Ive matched both to identical values by manipulating the BTR0 and BTR1 registers of the SJA1000 (NI's 9853) CAN controller. From what I know the FPGA on the cRIO runs at 40Mhz, with this a 20MHz clock for the NI9853 is possible. Here is the thing, when selecting the properties for the 9853 module and selecting a preset from the "Baud Rate" drop-list for any CAN port, if the "Advanced" button is pressed the "Specifiy Baud Rate as Bit Timing Registers" value changes accordingly to the preset value specified in the drop-list, that is, if I select 1000 kbits/s, BTR1 gets the value 0x14 and BTR0 gets 0x00; if I select 500 kbits/s BTR1 gets 0x1C and BTR0 gets 0x00. Also on the same properties window for the 9853, there is a "Module" tab, with a drop-list labeled "Module Clock" the values I can select here are 20Mhz and 10MHz. Turns out that the value of the baud rate as specified in the advanced tab by the bit registers is not affected if I select 10Mhz or 20Mhz; also in order to have a 1000 kbit/s speed with a 0x14 value on BTR1 a 16MHz clock speed should be used (according to the definitions of the SJA1000's datasheet for BTR1 and BTR0). The following images show what Im talking about:
Also all documentation I could find regarding nonstandard baud rates on the NI site apparently refers to the CAN controller NI hardware series 1 used (Intels 82527, which actually runs at 16Mhz) from what Ive been able to research this chip has identical Bit timing registers to the ones of the SJA1000 controller, proof of this is the document labeled "How to Configure CAN Ports for Custom Baud Rates" (http://zone.ni.com/devzone/cda/tut/p/id/4304), which shows a map of the registers of Intels chip, and is identical to the one found on the SJA1000s datasheet. On other document titled "How Can I Set Nonstandard Baud Rates in NI-CAN?" (http://digital.ni.com/public.nsf/allkb/CBA1FC627FFA0F8F862564DC0071B3A7?OpenDocument), the same information appears regarding the way the NI-CAN driver handles baud rates (again using Intels chip, which by the way is incorrectly specified to be running at 8Mhz). Using 20Mhz and the BTR1+BTR0 combination 0x1400, the SJA1000 yields 1.25Mbits/s, not even a possible speed on the CAN bus. Bottom line is, I think I cant interface my CAN network with the NI 9853, because of this strange issue. Im just wondering if anybody has any idea how to do this, or at least what is the speed the 9853 module runs on, with this I think I could at least try and find a value to match the 1Mbit on my network. Finally Ive attached the project Im running on the fpga target (Ive set the Module Clock on 20Mhz, disabled auto-start for both CAN ports and specified to run the Baud rate from the time registers using BTR1: 0x34 and BTR0: 0x00 values for the timing registers). Any help will be appreciated, thanks in advance...

One final thing, this is the only thing regarding external sync that Ive found so far....its the "NI CAN Product Compatibility and Feature Table" (http://zone.ni.com/devzone/cda/tut/p/id/5859#_ftn1) take a look at the footnote it says a digital module is needed, would it be a digital 9401 module? Ive also got one of those.

MEM#0A -2GB - if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#1A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?
MEM#2A -2GB- if we Upggrade to 4GB what will happen to the existing 2GB RAM?

So, I understand that the above server will have 32 GB Ram as our company ordered recently, Correct?
In the specifications of M4000 i see that for these servers we can upgrade he Ram upto 128 GB.
Please guide, any help offerred is appreciated.

A Key document is:
http://docs.oracle.com/cd/E19855-01/819-2210-14/819-2210-14.pdf
The m4000 can have 4 memory modules.
Each memory module can contain up to 8 dimms. (Two groups on same size (A and B) of 4 dimms). Group A dimms may must not be smaller than Group B dimms. (within a memory module).
The server can contain 4 memory modules of 8 dimms ... 128GB is attained by 32 4GB dimms. ( 8GB dimms used to be purchasable but are now discontinued ).
Depending on what you purchased to achieve 32GB on your server then following options are available:
- If you purchased 2 memory modules of 8GB each simply put these in two unused module slots and goto 32GB
- If you purchased 2 memory modules of 16GB each simply put these in two unused module slots and goto 48GB
- If you purchased 4 memory modules of 8GB each using 8 x 1GB dimms then move your existing simms into the group A slots of the new memory modules, goto 40GB and sell the spare dimmms on ebay or put them certain DELL's (then watch the thing crash due to a static dimm destruction issue and possilbe issues as it isn't supported.)
- If you purchased 8 2GB dimms stick them in your existing memory modules
- If you purchased 16 2GB Dimms ... and don have spare empty memory modules sell spares on ebay.
.... There may be further options ....
In general the person you are purchasing from should be giving good advice ... better than mine above.
... My cynical opinion is a lot of partners (and perhaps even Oracle itself) supplying the purchase may be on commission and have no interest and little care in minimising your cost .... having seen the performance of some oracle 'partners' in the uk I can see why some customers might want to move away from oracle hardware.
Please be aware certain games with switching things about could affect your warrantee ... ( its highly embarrassing when a failing disk in a dilbert has the wrong part number or even worse an incorrect backplate affecting the airflow ... ) ... and what you are really paying for is for an engineer to come and sort your server out if there is a hardware issue. So take some of the suggestions above with a pinch of salt.
Please be aware while have I tried to be accurate above I may have made a mistake. ... .... (in fact knowing me I probably have).
Edited by: bigdelboy on 26-Jan-2013 03:51 (NB: adding memory to servers is often a difficult balancing act and may not be cost effective .... and may make smaller dimms redundant in an upgrade in order to maintain supportable/workable configurations). A new T4/T5 may be more cost effective}. Buying fully populated at the beginning is also often more cost effective .... though the largest dimms to achieve highest capacity may be cost prohibitive.

"Moo" = Right fan repeatedly spinning up and down under certain conditions

I am pretty certain I have figured out what is causing the "moo". Here is my theory based on a couple of weeks of experimentation...
It is the right fan starting up and stopping. Again..and again...and again. It does this in response to temperature changes. But the threshold is too sensitive so what happens is an increase in temperature triggers the fan, the fan winds up and in so doing after a couple of seconds this immediately drops the temperature below the threshold and so the fan winds down. The temperature now builds and after a couple of seconds the fan spins up again. It will keep doing this until either activity falls so that the temperature stays below threshold or continuos activity ensures the temperature stays high enough to keep the fan on at low speed (when it is generally quiet unless there is a heavy load).
I will guess the cause is probably a faulty sensor, faulty fan or most likely faulty fan control logic since this is clearly happening with a lot of MBPs. If it is the latter then presumably they need only change the firmware controlling the fan to make it start slower and stay on longer.
Why doesn't everyone hear it?
a. Like most fan type noises they are only apparent in a quiet room - as most people work in rooms full of white noise they simply will not hear it even if it happens.
b. Some people have better hearing and are more sensitive to noise.
c. It needs the right set of hardware and sofware activities to trigger the problem...............
In my particular case I typically have my 2.0ghz MBP connected to an external monitor, ethernet and external USB mouse on the right side of the MBP. When I am using the MBP standalone (ie without more heat being generated) the noise does not occur as often, presumably because when idling less heat is generated.
As you change what you are doing with the machine (not sure if its CPU or Video related changes that matter most) the noise will start or stop happening. Doing absolutely nothing typically means the noise does not happen so often, but then again it can be sitting doing nothing and it will start happening. Doing a bit means (say 10-30% CPU) means it will make a noise , doing a moderate amount (say above 40% CPU) means it does not happen because the temperature stays high and the fan stays on - generally being quiet at low speed. If you push the machine (say 80% CPU) then a louder fan noise is noticeable. I have also found that opening/closing the lid (when using an external monitor) makes a difference, the surface it is on makes a difference and the room temperature probably does as well.
A good way to experience this is to start Garageband recording the noise when it happens since the additional load stops the noise. The spin up/down cycle will continue for 4 or 5 cycles as you record the noise but then the fan remains on very low speed as a new higher thermal equilibrium is achieved.
For reference I am on my 2nd MBP (the first also had this problem but it was less noticeable) and have experienced most the other noises:
a. Left Fan always runs on both machines
b. Screen buzz when not on full brightness on 1st MBP not in on 2nd.
c. CPU whine was not on 1st MPB but it is on the 2nd - but only at low level and only if running on battery power.
I have a couple of other irritating problems:
d. Screen dims after 2 minutes regardless of power setting etc.
e. Fit of 1st MBP was great, 2nd not so good.
Personally I find the fan spinup/down noise very very annoying, far more so than the left fan always being on. I really do need Apple to fix it, but I dont see the point of sending the machine in unless they recognize the problem and have a systemic solution since clearly this is common problem. Otherwise the chances are a tech will plug it in standalone in a noisy repair shop, hear nothing and either do nothing or never know if its fixed or not. So far no intelligent response from Applecare......If I can figure this Apple ought to be able to and get a fix.
And no I would not recommend buying a MBP until this problem is fixed if you are at all sensitive to noise and work somewhere quiet - because it appears to be a gamble as to whether you will get a quiet MBP or not. That's a shame since otherwise its a very slick machine.

I agree with u; however:
-The left fan that's always on is the Hard Drive - listen to the hard drive to the left of the trackpad and you'll realize that it is coming from there.
-My "moo" sound comes from my LEFT fan. So if it's a firmware issue, why would the side of the fan affected by the problem varry? this leads me to the worrying assumption that it is a hardware issue...If this is the case, who knows if apple will even cover it under warranty if it doesn't affect the performance of the system...

Satellite R630-155 - Fan is too noisy and SSD upgrade

I am the owner of a Toshiba Satellite R630-155 (Core i5-480). My problems are:
1. The fan is too noisy and never stops. In normal operation (browsing and general office work) there is a constant high pitch noise that is audible three to four meters away in an office environment - in high load you just can't stand it!!! The fan never stops... even when you are doing nothing...
2. Heat is a big problem. The bottom of the laptop is constantly overheating and i have to place it on my desk in a way that the bottom left corner is outside of the table so it can breath fresh air from below - if not, the temperature rises and the (loud) fan is unable to keep up. When i work with the laptop while sitting on a sofa, i have to place a thick book between the laptop and my legs. The book must be thick (more than an inch) with hard covers, otherwise the heat passes through the book!!!!
3. Last (but not least, i just mention the biggest problems here) it's the problem with SSD installation. I bought a used Corsair F80 (80Gb SSD) from a friend, but i was unable to use it with the Toshiba - the BIOS was not detecting the disk. I tried installing all latest firmware updates for both laptop and SSD but i had no success. Then i gave the disk back and i bought a brand new Zalman 128Gb SSD (SSD0128N1 Sandforce) but i had exactly the same problem. I contacted my local Toshiba support and after a lot of conversation the only answer i got is that the laptop is not compatible with those SSD's and this is acceptable by Toshiba and not their problem. They told me that if i need an SSD upgrade i can only go for the Toshiba SSD that is installed on the portege series, which is sold by Toshiba for a ridiculously expensive price - about $500 for 128Gb. I contacted the European support center and i got the exact same reply. I searched on the Internet and i found someone else with the exact same problem with a Corsair 128Gb SSD - he found that the laptop detects the SSD after ten to twenty reboots. I tried that and it was true - after a lot of reboots the laptop detected the Zalman disk and i was able to install Windows 7 successfully, but the process is unacceptable. Also the disk is benchmarked by official sites at the speed of an OCZ Vertex 2 128Gb (and slightly better), but when i ran a benchmark in the Toshiba, the results I got were below half of the advertised speed. Same benchmark in another machine for the same disk, resulted in the advertised speeds.
Shame for Toshiba... nice design and portability but everything else is a big flaw. Their support in non existent and they do not value their customers. I feel they stole my money and I'll never buy a Toshiba laptop again.
Sorry for the big message, but I need I have to warn potential customers. Can someone help me with any of the above problems? Do you have the same problems too?
To be continued...

Hi buddy,
Regarding the fan and heat issue: Did you make BIOS update? Friend of me has Satellite R630 too and he told me that fan activity with new BIOS version 2.10 is reduced. Furthermore the notebook is cooler than before so I would recommend installing this update. You can download the BIOS update here:
http://eu.computers.toshiba-europe.com > Support & Downloads > Download Drivers
But before you start the BIOS update you should consider the following tips:
-Run update as Administrator only
-Unzip all files from zip archive before you start the update file
-Close all running programs and also the antivirus and firewall
-Make sure that battery is fully charged
Regarding the SSDs its always a little bit complicated installing 3rd party products and nobody can guarantee that such parts would work. You are always on safely side with original Toshiba spare parts.
Everything what you can do is installing the newest firmware for SSD and hope that it works but who knows maybe the BIOS update will also help you in this case ;)

Hi Jackson,
Yes its is possible. Connect the storage array to the fabric interconnects using two 10GB links per storage processor. Connect each SP to both fabric interconnects and configure the ports on the fabric interconnect as “Appliance” ports from UCSM
For more information on how to connect Netapp storage using other protocols like iSCSI or FCOE please check the url below.

Cisco wastefulness : 3845 fan module

We had a fan fail on our 3845 edge router. No big deal; the other two fans kept the temperature easily within spec, and the module is a two minute hot swap. I opened a ticket, they sent me a replacement. Simple. (In fact, the router install docs note that the fans are essentially a "consumable" part, and will fail within a few years, depending on how hot and dusty your environment is.)
The fan module is actually the whole face plate of the router, blue plastic with a steel backing, status LEDs, and the three fans.
That is all fine. But, Cisco won't take the failed part back for refurbishment, which in this case would be simply to replace the fans!
The replacement part came with the standard Cisco return packaging: a sticker with an RMA #, a "manual" paper UPS label, and instructions to use their on-line tool ( www.cisco.com/go/logistics ). But, when I entered the RMA number, I got a pop-up saying it was invalid, and I should call Cisco Asset Recovery, whose 800 number is also on the sticker.
They told me that this part is not returnable; that the RMA is only to ID the shipment so they can confirm I got it. They told me to just throw it out. They would not provide a printable return shipping label.
I'd feel bad throwing out even the substantial cardboard and foam packaging of this part, let alone the assembled unit!
Hasn't Cisco heard that there is a general industry movement to cut down on electronic waste? With the removal of six screws, I could swap the failed fan out of this assembly and replace only the fan. I'm glad Cisco didn't ask me to do that level of repair, but I certainly think they should -- I'd assumed that the replacement unit I'd received was a return "refurbished" with new fans.
It seems a complete waste to just chuck out this whole thing.
Heck, even the tiny power supply bricks for the Aeronet APs have a little "no trash" sticker on them, with a link to http://cisco-returns.com . Why do they just dispose of router faceplace assemblies when the only issue is a fan that was expected to fail in the first place?
Anyone have a justification for this waste, or is it just Cisco being too big to care?
Attached photo shows the 3845 front piece, which is the fan assembly, and the package the replacement came in, which could be used to return this part, and then be reused. For comparason, the little black thing in front is an Aeronet 1131 power module, which has a Cisco Recycles sticker.

Cost effectiveness.
Basically, the fan unit is worth maybe, I dunno, $50 to manufacture? It'd cost Cisco probably $25 to pay the shipping back for the failed part, and then half an hour of someone's time to refurbish/clean/test the replacement unit - and, since they'd probably replace all three fans at the same time, you're effectively only sending them the mounting plate.
It's simply not cost effective.
HP have a similar process when it comes to failed memory modules - if they ship you a replacement memory module for, say, a laptop which has an issue, they don't bother having the dead one shipped back - it's simply not worth the shipping and handling costs to recover a part worth maybe $75.
It's harsh, and environmentally unsound, but Cisco is like most big companies - they're in it to make money, and wasting money like that simply isn't how John Chambers justifies his existence to the board!
Cheers.

Fans Constantly Cycling On and Off

About a week ago the fans on my dual 2.0 G5 running 10.4.8 started cycling on and off. After a few days of this I ran AHT and received the following error:
Error Code 2STH/1/2:CPUA AD7417 AD1.
I found out this was a possible problem with the logic board and immediately took it in to the local Apple authorised repair center. They tested it and found a Thermometer failure on CPUA AD7417. They removed both processors, reset the logic board,reinstalled the processors, and completed calibration. After which they ran ADT test and Apple G5 Service test disk twice. According to them the G5 passed all the tests and had no problems.
After I got home and set it back up the fans started cycling on and off just as they did before I took it in for repairs–they cycle on and off regardless of the ambient temperature or the amount of work the processors are performing. I ran AHT's extended test which it passed with no problems.
What's going on? Did they mess up when they were doing the calibration? Am I going to have the same problems that prompted me to take it in for repairs to begin with? Is there a serious hardware problem that they failed to discover?
The service was poor, and they even managed to scratch the **** out of the side of my G5, so I don't really want to take it back to them again. Unfortunately the closest Apple Store is about 4 hours away and my G5 is no longer under warranty.
Any suggestions about what's causing the problem and what I should do would be really appreciated. Thanks.

Blinn–
Nope, I hadn't installed a software update. It just came out of nowhere. If you haven't done so, I reccommend running AHT to see what it shows. Hopefully you're just having a software problem.
DaddyPaycheck–
Thanks. That clears it up. I am definitely going to call Apple. I am really fuming about the lack of service I've had from the "Authorised Repair Center."
UPDATE
It just keeps getting worse. Now the G5's fans are really revving up and it is putting itself to sleep with increasing frequency. I just got off the phone with the guy who "repaired" it. The reason that AHT is showing the same error code, but on processor B is because when he reinstalled the processors after resetting the logic board he switched them. According to him, this error shows that it is a problem with processor B, which will need to be replaced. It's going to cost $581 for the CPU–no charge for labour since I've already paid to have it fixed once even though it wasn't!–but I don't think I want anyone at that shop working on it again.
Has anyone else replaced a CPU in a dual 2.0 G5? How much did it cost you? Is this something that I could do myself?
I think that before I do anything else I'm going to take DaddyPaycheck's advice and call Apple. At least then Apple will know that this authorised repair center is doing a terrible job!

UCS C series maximum hard drive size

Looking for info on the maximum hard drive size support on teh UCS C series. I have a C200M2 that I added a 4TB drive, I have updated the server to the latest firmware and BIOS however the server shows the drive size is 2TB.

Hi! and welcome to the community mate!
Here is the table that shows the supported disk's PID for the C200 server:
http://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-c-series-rack-servers/c200m2_sff_specsheet.pdf
If you successfully installed ONE HDD of 4GB and made it work, you were lucky cause I don't see any disk with that size, I have not even seen a disk of that size for UCS yet.
I am wondering if perhaps you installed 4 disks of 1TB and configured them in RAID 1 which would explain the reason for the size to go down to half of the capacity of the array as RAID 1 is a mirror.
Let me know if I misunderstood you.

Ask the Expert: Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI with Vishal Mehta and Manuel Velasco.
The current industry trend is to use SAN (FC/FCoE/iSCSI) for booting operating systems instead of using local storage.
Boot from SAN offers many benefits, including:
Server without local storage can run cooler and use the extra space for other components.
Redeployment of servers caused by hardware failures becomes easier with boot from SAN servers.
SAN storage allows the administrator to use storage more efficiently.
Boot from SAN offers reliability because the user can access the boot disk through multiple paths, which protects the disk from being a single point of failure.
Cisco UCS takes away much of the complexity with its service profiles and associated boot policies to make boot from SAN deployment an easy task.
Vishal Mehta is a customer support engineer for Cisco’s Data Center Server Virtualization TAC team based in San Jose, California. He has been working in the TAC for the past three years with a primary focus on data center technologies such as Cisco Nexus 5000, Cisco UCS, Cisco Nexus 1000v, and virtualization. He has presented at Cisco Live in Orlando 2013 and will present at Cisco Live Milan 2014 (BRKCOM-3003, BRKDCT-3444, and LABDCT-2333).

Hello Evan
Thank you for asking this question. Most common TAC cases that we have seen on Boot-from-SAN failures are due to misconfiguration.
So our methodology is to verify configuration and troubleshoot from server to storage switches to storage array.
Before diving into troubleshooting, make sure there is clear understanding of this topology. This is very vital with any troubleshooting scenario. Know what devices you have and how they are connected, how many paths are connected, Switch/NPV mode and so on.
Always try to troubleshoot one path at a time and verify that the setup is in complaint with the SW/HW interop matrix tested by Cisco.
Step 1: Check at server
a. make sure to have uniform firmware version across all components of UCS
b. Verify if VSAN is created and FC uplinks are configured correctly. VSANs/FCoE-vlan should be unique per fabric
c. Verify at service profile level for configuration of vHBAs - vHBA per Fabric should have unique VSAN number
Note down the WWPN of your vhba. This will be needed in step 2 for zoning on the SAN switch and step 3 for LUN masking on the storage array.
d. verify if Boot Policy of the service profile is configured to Boot From SAN - the Boot Order and its parameters such as Lun ID and WWN are extremely important
e. finally at UCS CLI - verify the flogi of vHBAs (for NPV mode, command is (from nxos) – show npv flogi-table)
Step 2: Check at Storage Switch
a. Verify the mode (by default UCS is in FC end-host mode, so storage switch has to be in NPIV mode; unless UCS is in FC Switch mode)
b. Verify the switch port connecting to UCS is UP as an F-Port and is configured for correct VSAN
c. Check if both the initiator (Server) and the target (Storage) are logged into the fabric switch (command for MDS/N5k - show flogi database vsan X)
d. Once confirmed that initiator and target devices are logged into the fabric, query the name server to see if they have registered themselves correctly. (command - show fcns database vsan X)
e. Most important configuration to check on Storage Switch is the zoning
Zoning is basically access control for our initiator to targets. Most common design is to configure one zone per initiator and target.
Zoning will require you to configure a zone, put that zone into your current zonset, then ACTIVATE it. (command - show zoneset active vsan X)
Step 3: Check at Storage Array
When the Storage array logs into the SAN fabric, it queries the name server to see which devices it can communicate.
LUN masking is crucial step on Storage Array which gives particular host (server) access to specific LUN
Assuming that both the storage and initiator have FLOGI’d into the fabric and the zoning is correct (as per Step 1 & 2)
Following needs to be verified at Storage Array level
a. Are the wwpn of the initiators (vhba of the hosts) visible on the storage array?
b. If above is yes then Is LUN Masking applied?
c. What LUN number is presented to the host - this is the number that we see in Lun ID on the 'Boot Order' of Step 1
Below document has details and troubleshooting outputs:

LabView code module to perform simple pass/fail *IDN? query?

LabView 7.1, TestStand 3.1, NI PCIGPIB board controlling a communications service monitor and a power supply. I'm having problems with my application sync correctly between the service monitor and GPIB board. I suspect the driver. Does anyone have a simple LabView code module to perform a *IDN? with a partial (in case they change firmware versions)string comparison that I can use in a TestStand seq. At this point if failure I could pop-up and tell operator to abort test and reboot instrument. (only way I've found to clear the buffer). Note: At times this app works fine and is inconsistant in failure times/rates.
Sorry so wordy and thanks in advance.
Using LabVIEW 2010SP1 and TestStand 4.5

Thanks for the reply Craig.
I've found I can perform a *IDN? using the Instrument I/O Assistant.vi. Ive placed this on a new block diagram and am changing it as I need. I've found in this particular case the *IDN? yields 3 tokens one of which I can use to perform a string comparison on. This will give me a boolean which I can wire to the pane for use by TestStand.
