B22-M3 and Boot from SAN with W2008 R2 SP1

I have a rather weired situation.

Service profile with boot from SAN

Associate with a B22-M3

Boot lun visible

Installing W2008 R2 SP1 on a boot lun (HDS storage) works perfekt

However, boot fails ! we see Windows starting, and then it starts loop, booting again and again

Associating this same Service Profile to a B200-M3 works, Boot from SAN is ok

Has this been seen ?

Hey Wdey,

I just wanted to let you know that someone I worked with was running into the same issue and we found that what the problems problmes was related to the defect below.

Walter,

Which adapters are you using in the B22 and B200?

Hi Robert

B22-M3 has a MLOM, B200-M3 has MLOM and VIC-1280

I have seen some issue, which could explain the issue: the memory Dimm's in the B22-M3 are not properly configured ! I have to investigate further and let you know.

Btw. I forgot to mention, that for the B22-M3, Windows actually blue screens, upon booting from the lun.

Cheers

Walter.

Yeah that BSOD could be a problem.  I'd also remove the VIC 1280 from the B200 to ensure the VIFs aren't being instantiated on it.  Compare Apples:Apples this way.

Looking forward to your update once the memory issue is sorted.

Hi Wdey,

Is the firmware on both the B22 and the B200 server the same? If not lets make sure that the servers are running the correct firmware.

Thank you

Hi Manuel

UCS domain run's at 2.1.3a

Firmware on both blades are at 2.1.3a as well

Is this correct ?

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

That does not seem right...

If he wants 32 GB of memory, he needs to configured it like:

B0  B1   C0   C1   D0   D1

4     4      4     4      8       8     <<<< DIMMs size

What he can do is to move the 16GB DIMMs and move them to D0-D1 and buy 4x 4GB to install them in B0-1/ & C0-1 to have 48GB DIMMs and take advantage of the DIMMs he already has

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Thanks Keny ! This configuration is also running at 1600 Mhz (if Dimms and CPU support 1600 Mhz) ?

I have yet another question, of a 2 CPU, 8 x 16G Dimm (128GB) B22-M3, where discovery fails ! could this also be a memory configuration misconfiguration ?

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

According to the installation guide for B22-M3

4

B0, C0, D0, B1

F0, G0, H0, F1

Above should be ok and run at 1600 Mhz ! please confirm ?

VIP Red

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Keny, now I'm really confused.

If you look at the installation guide of B22-M3, table 2, http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.pdf, it says B0, C0 !! which contradicts, whats in the B22-M3 Spec

Table 2: Preferred DIMM Population Order

DIMMs per CPU CPU 1 installed slots CPU 2 installed slots

1 B0 F0

2 B0, C0 F0, G0 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

3 B0, C0, D0 F0, G0, H0

4 B0, C0, D0, B1 F0, G0, H0, F1

5 B0, C0, D0, B1, C1 F0, G0, H0, F1, G1

6 B0, C0, D0, B1, C1, D1 F0, G0, H0, F1, G1, H1

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Walter,

I think the confusion here is the fact that both (the spec sheet and the installation guide) talk about either 1 DIMM per channel OR 2 DIMMs per channel.  Your customer is doing both at the same time  {EDIT: I am not saying that is wrong, I am saying that is the confusion you see when looking at both documents}

-Kenny

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Hi Kenny et al

Just to summarize the inital problem, again, and highlight the discrepancy in different Cisco documents.

Customer ordered B22-M3 with one CPU and 2 x 16 G Dimm.

He then opens the blade, and compares the shipped configuration, which I assume is done like in the B22-M3 spec


http://www.cisco.com/en/US/prod/collateral/ps10265/ps10280/b22m3_specsheet.pdf
Table 24 , namely D0, D1 (as Kenny said above)

customer then checks http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.html
Table 2, which says B0, C0

And changes B0, C0 to D0, D1, which might be wrong !!!!

Thanks for any clarification ! it's urgent

Thanks Walter.

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Walter,

How much memory did your customer wanted to have installed in the server (as a total and not per CPU) ?

-Kenny

VIP Red

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

B22-M3 with one CPU and 32 GB; with 16Gb Dimm's

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Walter,

Ok, so I understand he wanted 32GB in the server, with only 2 DIMMs in CPU1

http://www.cisco.com/en/US/prod/collateral/ps10265/ps10280/b22m3_specsheet.pdf Table 24  <<< This only applies if you are mixing 4GB DIMMs with 8 GB or 16 GB DIMMs, since there is no mix in the server, that table does not apply.

Then, as I mentioned above, if he wants 32 GB of memory, he needs to configured as shown below and that involves mixing 4&8GB DIMMs:

B0  B1   C0   C1   D0   D1

4     4      4     4      8       8     <<<< DIMMs size

Now, since he is not doing a mix, he has 2 options:

1- If he uses the 1DPC option, he may provision the server with 24, 48 OR 96GB total  (other options have not gone through QA, reason why other options are not documented. Does not mean it does not work, it means it was not fully tested)

2-If he wants to use only 2 DIMMs (which is different to 1DPC & 2DPC options) he can install DIMMs in Slots B0&C0, as per     Table 2 in http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.html    <<<<< So, I was initially wrong cause I ignored this "Table 2", please excuse me

{EDIT} I will look to see if table 2 (from http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/blade-servers/B22.html )   can be included in

http://www.cisco.com/en/US/prod/collateral/ps10265/ps10280/b22m3_specsheet.pdf to avoid anyone else ignoring one or the other.

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Thanks Kenny

If you read above, this is what the customer actually has, 2 x 16G Dimm's in B0, C0

This means the blue screen during the boot from san problem is still not resolved.

Walter.

VIP Red

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Or a more basic question: is a 32 GB memory configuration for B22-M3 and one CPU supported ? I only see the smallest configuration starting at 48 GB.

VIP Red

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Btw. this 32 GB Memory configuration ( 2 x 16G Dimms) is running at 1000 Mhz !!!! is this ok ????

Processor is Xeon(R) E5-2403, Memory Dimms are 1600 Mhz capable

Re: B22-M3 and Boot from SAN with W2008 R2 SP1

Walter,

If you have not, please open a TAC case if you dont mind and ask for the confirmation in regards to the correction/confirmation about the docs discussed, it is complicated without the case number for me.   You may open the case with the keyword "Product Questions and Features"

Hi Wdey,

About this post, do you remember what you did to resolve this issue?

Thanks

B22-M3 and Boot from SAN with W2008 R2 SP1

Hi Manuel

Very strange indeed !

customer did erase the whole UCS domain, and started after a power cycle from scratch (initially this was only a PoC); and then the whole problem disappeared.

I think, too many changes have been done, without actually doing disassoc / associate the SP; this might be one of the problems.
