6120 link down on mgmt0 triggers not UCS Manager failover cluster - is?

Hello friends

We have recently installed a cluster consisting of two 6120 UCS s configured for HA. When executing fail during test cases, we removed the network cable in mgmt0 on 6120 elementary. Immediately the cluster IP address is not responding ping (as expected) and we lost connectivity to the UCS Manager GUI (also as expected.) At one point, however, we expected the 6120 subordinate to detect that this link was down and launch a failure over the UCS. This is not moved after 20 minutes of waiting.

My questions are the following:

  1. Is this expected behavior?
  2. If this is not the case, what should us review to ensure that failover occurs in the future?

I know we can force a failover of the subordinate by issuing a command to the main cluster of local-mgmt but would be interested to see if it should be automatically produced on the failure of primary mgmt0 binding.

Thank you for your time.

Configured by default which is the expected behavior.

You can configure management interface and failover if the management interface loses connectivity such as your test scenario.  That's what you're looking for.

Admin - Communication Management - Management Interfaces - Management Interface tab strategy control tab.

Kind regards

  • Cisco 6248 FI to Brocade 6510 SAN switch shows Link Down

    Hi all

    His new installation of Cisco UCS with Brocade SAN switch 6510.

    I followed the Cisco UCS to Brocade connectivity Guide.

    Even if the switch side so FI link is not coming. No lights are glowing.

    When I checked the switchshow @Brocade 6510, ports are No_Light status display. Where in other ports, it indicates the number of my storage device WWN.

    At the END, when I click on ports CF, its projection on all State - link down.

    Any who are facing this problem. ?

    Am I missing some configuration steps?

    Kind regards

    This should be a trivial or a very complex problem. I'd rather commonplace.

    Brocade is a CF 16 G switch; up to 8 G negotiation seems to work (storage subsystem).

    Maybe you could try to set the speed on the Brocade 8G port fix!

    Or something with the cables is wrong? Send / receive Crusaders?

    Are shortwave of the MMF SFP? cables connection as well?

    Connect cable from port for example. 31-33, 32 to 34 and see if it works?

  • Fault clearing UCS Manager on linking rising unused C-series adapter

    I have a number of C240M3 servers in an infrastructure of the UCS.  They have all two adapters VIC 1225 and when they were connected to the start, technicians accidentally connected the second card on some of them to the aircraft.  For now at least, we want to only first used adapters (two ports - one for each FEX).  However, as map 2 was connected at a given time, UCS Manager will not stop giving these flaws:

    F0206 - adapter 5/2 is inaccessible

    F0209 - link interface rising adapter 5/2/1 the link status: unavailable

    There is not a way to erase the mistakes without this second reconnecting.  Re-recognition of the server has not helped and I'm not sure I want to try their decommissioning and then get them to appear in the UCS.

    Does anyone know how to clear these faults manually?

    Open a TAC case and get TAC watch mistakes, then we can try to delete them, if they are real error messages.

  • I'm looking for a link to XP SP1 does not require a network connection to install

    I'm looking for a link to XP SP1 does not require a network connection to install

    Were you recently doing a Clean Install? I ask because you are implying in your installation of Windows XP is in 'gold' or SP0 (i.e., pre - SP1) level. Well sure, automatic updates will not work!
    You can use this path to level – says in passing:
    Gold XP to XP SP2 to XP SP3.
    Note that installing SP1a is TOTALLY USELESS!
    Here are the detailed instructions:

    1. download the installation of SP2, SP3 and IE8 files. I prefer to keep these on a USB key, but this is optional. Here are the links to all the installation of three files:

    http://www.Microsoft.com/download/en/details.aspx?ID=28 (for SP2)

    http://www.Microsoft.com/download/en/details.aspx?ID=24 (for SP3)

    http://www.Microsoft.com/download/en/details.aspx?displaylang=en&ID=43 (for IE8)

    And if you wish, download the Setup file of a good anti-virus program. I recommend Avira free Antivirus:

    http://www.Avira.com/en/Avira-free-antivirus

    2. disconnect Internet.

    3. temporarily disable the automatic updates.

    4. install SP2. Restart twice.

    5 install the SP3. Restart twice.

    6 switch to IE8. Restart twice.

    7 install an Antivirus software.

    (What happens very often is that someone has their software antivirus running as they try to install SP3, which often translates into chaos! "This is why it must be done after installing SP3 and IE).

    8 make sure that firewall Windows is activated (it should be).

    (Now you can physically reconnect to the Internet.)

    9 visit Windows Update to download and install only the critical security updates.

    10 re - enable automatic updates.

    After the back if you need guidance.
