Few things to keep in mind when integrating a rack mount server with UCSM:
-CIMC settings must be reset to factory defaults
-As long as you configure the cable management per the Cisco documentation, the server will automatically be discovered by UCSM (just as if you inserted a new blade)
-If you need to decommission a rack mount server for any reason and what to again integrate it with UCSM, don't forget to recommission it from the decommissioned tab
-The VIC card needs to be P81E or 1225 (NOT 1225T)
-SFPs should be the same on FEX and server side (I used Twinax cables in my environment, which are also supported)
-C-series server needs to be running firmware version 1.4(6) or later.
Will add more tips to this post as I run into them.

Belkin KVM Switch
More so for my own knowledge...
In order to switch between the hosts connected to a Belkin KVM switch: SCROLL LOCK, SCROLL LOCK, up arrow/down arrow.
Alternatively, if you want direct access to a specific server you can do so with: SCROLL LOCK, SCROLL LOCK, 0 + server number. (i.e. If trying to view the console of server 2: SCROLL LOCK, SCROLL LOCK, 0, 2)

UCS Core File Exporter
Bet you didn't know about this...
UCS has a feature built-in that will allow for the export of core files off of the system as soon as they occur to a specified TFTP server. In order to configure this feature, known as the Core File Exporter, you will need to navigate in UCSM to the Admin tab -> Faults, Events and Audit Log -> Settings. On the right hand pane, you will see a Core File Exporter tab, which will need to be enabled.
One the feature is enabled, you will be able to enter the TFTP server hostname/IP and remote path.
Whenever a core file is written to the UCS system, it will be automatically be sent to the configured TFTP server.
This feature can also be enabled via the CLI: http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/cli/config/guide/1.3.1/CLI_Config_Guide_1_3_1_chapter40.html#task_00981534E203404D9D4B547FF17D8FDB
Great feature for system monitoring and automatic export of core files to be included in TAC cases!

Rehost Nexus 1000v Licenses in Minutes
We have all been there. Nexus 1000v license re-hosting because something happened to our VSM and we needed to re-install... the LUN got corrupted... the host-ID magically changed somehow... etc, + hours on the phone trying to accomplish this task. Instead of opening up a Licensing case, you can actually complete the re-host via Cisco's License Administration Portal in under 5 minutes!
You can access the portal via the following link: https://tools.cisco.com/SWIFT/LicensingUI/lookupLicenseForRehost
Once you log in, the link will take you directly to the 'Initiate a Rehost' option. There are few other options available from the menus atop the page. You will need to check the box next to the license file you would like to transfer/rehost (you can differentiate by Host ID in the case of a 1000v license).
This procedure will greatly expedite the time it takes to rehost the 1000v licenses!

After you click next, you will be prompted to enter the new Host ID of your VSM:
The final page is a review of the changes you submitted. Ensure that the Target Host ID is accurate. You will need to view and agree to Cisco's Software License Agreement. At that point you can click Submit and you will receive a confirmation pop-up. Your new license file will be emailed to the address associated with your cisco.com account, and you can go ahead and upload the new license file(s) to the VSM.
