I have a 9216i’s (nxos 4.2) and a 6120 (ucs 2.0) that I am trying to configure a san-port-channel to port-channel with and I can’t get it working. The FC (F-NP) links work when they are not in a po, but when I try to form a port-channel I get “invalidCfg” on the MDS switch. I am setting it up with only one link to start with. What is wrong with this config or is their a bug? The MDS switch has NPIV enabled.

Does anyone know how having two VSGs servicing a single tenant affects the “Host Scalability” of 12 VEMs per VSG? Per the docs each VSG can handle 12 VEMs. I am understanding this as a single VSG module can service up to 12 VEM’s (Hosts). What if the customer has 13 hosts? Do you have to add another VSG? I can’t find anything in any documentation on what the impact is of adding multiple VSG’s to a single tenant. How does that affect the 12 VEM per VSG limit? ... View more

TITV is an open source project aimed to help you to document your UCS  system. TITV consists of a script which collects information from the  UCSM via the API. The script parses the XML data and then writes the  data to a report. https://sourceforge.net/projects/titv/ https://sourceforge.net/projects/titv/files/ Summary: TITV is an open source project aimed to help you to document your UCS system. TITV consists of a script which collects information from the UCSM via the API. The script parses the XML data and then writes the data to a report. The report consists of multiple excel files. The report output in the excel files isn’t pretty, but fully captures the system configuration and can be reviewed or linked to for documentation purposes. The script is an HTML application that is executed by “Microsoft HTML Application Host” which will be on your workstation by default. All code is fully viewable for review. Current version: v.15 Features: Single GUI for generating reports Captures most configuration settings of UCS system Compiles UCSM configuration details in sectioned excel files, Server, Lan, San, etc… Ability to spool reports by hardware o   All hardware or specific FI’s or Chassis Ability to spool reports by specific org unit(s) Ability to spool reports to “Detailed Naming” or “Link compatible naming” reports How to use: Open TITV-EXC.hta file Select directory where report files will be placed Enter URL (http://IP), Admin, Password for UCSM system Click “Connect” to connect the script to the UCSM Select either “Hardware” or “Organizations” Hardware: Select hardware; Fabric Interconnects, Chassis, or Rackmount servers Organizations: Select relevant org units Select “Detailed Naming” or “Link compatible Naming” Detailed Naming: The report files and excel tabs are detailed, actually reflecting the object name. Link compatible Naming: The report files and excel tabs are generic and sequential. The name and excel tabs are the same at each report run. This feature is to allow for excel linking for consistent linking between reports. Select “Generate Report” Give report “multiple minutes” to complete. It can take a while depending on how much data/link speed present. ... View more

When we shutdown a ESX host in vCenter the UCSM just reboots the server. The desired power state is "up" but where do you configure that setting so the server stays down after a shutdown? vSphere DPM is NOT enabled. I have looked all of UCSM for any setting that would be causing this and no luck. ... View more
