For the past 30 months, I have been working with the Routing Protocols and Core Architecture teams in Cisco Technical assistance centre. My daily work includes troubleshooting routing protocol scenarios, helping with new network designs and actively working with the Cisco BUs on fixing software issues.
I have great passion towards networking technologies and am always interested to extend my knowledge in other fields of networking like Firewalls and VPNs. My current areas of focus apart from the routing protocols are High Availability routing/switching Design, Fast convergence and application control.

B420M4 supported from 3.0.2 release
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/release/notes/CiscoUCSManager-RN-3-1.html#reference_0A561B21F59A413F8F263D58E28202B5
B420M4 was not supported in the first UCS mini release(3.0.1x) and you might have come across one such doc.
Currently mini supports all M3 and M4 blades except the B2604and B460M4s

Hi Barry,
There are different ISO to USB formatting tools that could be used
Personally, I've used the following windows application to create a bootable USB
https://rufus.akeo.ie/
How did you create a bootable disk previously ? and what error did you notice?
Can you try using this software and boot from the USB?
Please update us if this helped.
Regards,
Karthic

I think the UCS Mini specsheet might help. Please check page 38,39 - http://www.cisco.com/c/dam/en/us/products/collateral/servers-unified-computing/ucs-b-series-blade-servers/ucsmini-specsheet.pdf
It explains connectivity between B200M4 and 6324 when you have a VIC1340+port-expander/VIC1380 in the mezz slot. However in your setup you don't have an adapter in the second slot.
In general, the 6324 has 16 backplane ports starting 1/9 through 1/24 with 2 ports going to each blade. The second HIF port per blade will come up only when you have a second adapter(port-expander/vic1380)

Jim. You answered your query. The NIC speed reflected on the OS depends on the number of backplane connections to the blade from IOM.
.
In 6324 FI with VIC 1340 - Each FI/IOM has 1x10G trace per blade per fabric
In 2208 IOM with VIC 1340 - Each IOM has 2x10G trace per blade per fabric
Hence the OS sees 20G speed on blades connecting to the 2208 IOMs which basically has more backplane ports going to a blade.

I assume your UCS infrastructure is currently on 2.0/2.1?
Upgrade from 2.0.3 to 3.1.1 would need a two step upgrade from 2.0.3 -> 2.2 and 2.2 ->3.1.1e
So the steps are
1) Upgrade UCS infra to 2.2.x release
2) Upgrade blades to 2.2.x release
Procedure:
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/upgrading/from2-0/to2-2/b_UpgradingCiscoUCSFrom2-0To2-2.html
3) Upgrade UCS infra to 3.1.1e
4) Upgrade blades to 3.1.1e or a suitable release
Procedure:
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/ucs-manager/GUI-User-Guides/Firmware-Mgmt/3-1/b_UCSM_GUI_Firmware_Management_Guide_3_1/b_UCSM_GUI_Firmware_Management_Guide_3_1_chapter_01.html#concept_F4E8EB876BC949E2855327611B88B866
As mentioned in the link
"Before upgrading to Cisco UCS Manager Release 3.1, ensure that the existing infrastructure and server bundles are on a Cisco UCS Manager 2.2(x) release, or later releases.
Important:
Upgrading from infrastructure bundles earlier than Cisco UCS Manager Release 2.2(1a) is not supported."
Hope that helps

Jim,
What model of IOM do you have in the secondary chassis?
What model of adapter(s) do you have in B200M4? Do you have a port-expander in any of them?

UCS integration with 2348UPQ is supported in 3rd Gen FIs(6300). I don't see the info in 6300 specsheet but the following whitepaper has the info you are looking for.

Michael,
UCSM 2.2.4 adds the following feature to monitor IOM NIF port errors and by default triggers a warning if the number of errors increase the value of 5. You can use this feature to automatically shut down the port if the CRCs go beyond a particular value.
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/release/notes/ucs_2_2_rn.html#pgfId-282711 Policy-Based Port Error Handling—If Cisco UCS Manager detects any errors on active IOM Network Interface (NIF) ports, and if the Error-disable setting is enabled, Cisco UCS Manager automatically disables the respective FI port that is connected to the IOM NIF port that had errors.
When a FI port is error disabled, it is effectively shut down and no traffic is sent or received on that port.
The config can be checked/modified as shown in link below
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/sw/gui/config/guide/2-2/b_UCSM_GUI_Configuration_Guide_2_2/configuring_ports_and_port_channels.html#concept_451A029DEA0D4F2F9E78869D15A8E95E

This bundle name change is part of the SKU refresh which updates CPUs, FI models to the smartplay bundles.
However, there is no change with the UCS chassis . The new bundles has the same components as the old bundle.

You will have to install the drivers for the RAID card that you are using. You will have to unmount the windows ISO and mount the driver ISO to install the drivers. Then you will have to mount the windows ISO back The driver package can be downloaded from the link below http://software.cisco.com/download/release.html?mdfid=284444317&catid=282558030&softwareid=283853158&release=1.5(1d)&relind=AVAILABLE&rellifecycle=&reltype=latest Thanks, Karthic

Hi all, With UCSM at 2.2 based release, you can still have your server & adapter firmware at 2.1.3 with B200M2 and M81KR running ESXi5.5 and ESXi5.5U1. This has been already tested and shown in the interop matrix http://www.cisco.com/web/techdoc/ucs/interoperability/matrix/matrix.html This is a supported combination Thanks, Karthic

Do you want to delete only the VSM or the config on the N1110 itself? If its the latter, you can do a 'erase startup-config' like you do on a router/switch. Now reboot the N1110 and it would restart prompting you to input the details about the domain id,hostname,control vlan etc.. Thanks, Karthic
