Fixing, This host currently has no management network redundancy

VMware

host no management network redundancy

I recently redid my VMware home lab environment and after enabling HA the warning message “This host currently has no management network redundancy” started displaying on each of my ESXi hosts.

This warning happens because in a HA cluster there is a requirement for the management network to have redundant NICs, but in my case I’m using Intel NUCs which only have a single NIC and since this is only a lab I don’t care to see the warning so lets disable it.

Disable host currently has no management network redundancy warning

  1. First log into vSphere. I’ll be using the HTML5 client.
  2. Now select the cluster and click on the Configure tab then click on vSphere Availability and then Edit.
    host no management network redundancy cluster settings
  3. Click on Advanced Options and then Add the following option and value and click OK: 
    das.ignoreRedundantNetWarning    true

    host no management network redundancy advanced options

With that the warning message is gone. If you do still see the error then try turning HA off and back on or right clicking on each host and selecting Reconfigure for vSphere HA.

    I’ve been using vCenter Operations Manager for a while now at work for all the great information that can be found about our environment so I tend to log into vCOp at the start of the morning and then come back to as I may or may not need it thoughout the day. One thing that has kind of annoyed me is having to constantly log into the standard UI multiple times a day due to the default 30 minute timeout value.

    Luckily, with a bit of SSH and a few commands we can increase this timeout to anything we like or even disable it all together!

    VMware certified

    Starting today, March 10 2014, new VCP certifications must be re-certified within two years of it’s earned date. Anyone who currently has their VCP certification prior to March 10 2013 has until March 10, 2015 to re-certify.

    The new policy gives you three options to re-certify:

    1. Take the current exam for your existing VCP certification solution track. For example, if you are a VCP3, you could take the current VCP5-Data Center Virtualization (VCP5-DCV) exam.
    2. Earn a new VCP certification in a different solution track. For example, if you are a VCP-Cloud, you could recertify by earning VCP5-Desktop (VCP5-DT) certification.
    3. Advance to the next level by earning a VMware Certified Advanced Professional (VCAP) certification. For example, if you are a VCP5-DCV you could earn VCAP5-DCA certification.

    I can understand why they are doing this but I don’t agree with the changes. As per the announcement if you let your certification expire, “Your certification will be revoked,and you will no longer be entitled to use the certification logo or represent yourself as VMware certified“. Really? You mean everything that was done prior and after taking the exam means nothing?

    Just the other day we had a Windows Server 2008 R2 Standard physical server that needed to be P2V’ed, and after trying to use VMware Converter Standalone 6.1.1 we ran into the error message “Permission to perform this operation was denied” after entering the source machine details.
