When all your SuperMicro X9/X10/X11 IPMI sensors show N/A: the system is in a BIOS or boot selection screen

Posted by jpluimers on 2021/05/17

I have seen this happen on various Supermicro X9/X10/X11 systems including X9SRi-F/X9SRi-3F/X10SRH-CF/X11SPM-F boards:


I found this via:

  • [WayBack] IPMI no sensor readings and already reset | iXsystems Community
  • [WayBack] Supermicro X10 and X11 motherboard FAQ | iXsystems Community

    All the sensors read N/A 

    First of all, make sure you’re not in the BIOS setup menu. IPMI monitoring of sensors isn’t available there.

    If that is not the case, the procedures listed under “The CPU/PCH temperatures read N/A” may help.

    The CPU/PCH temperatures read N/A

    While the exact cause is unknown, the BMC may enter a faulty state, requiring a reset.

    The following options were recommended to me by Supermicro:

    • Start by power cycling the IPMI. This can be done from the web interface.
    • If that doesn’t work, reset it to factory defaults via the web interface and power cycle it (it will not work until it is properly power cycled).

ESXi 6.x download URL

Posted by jpluimers on 2021/05/17

Many of the ESXi download URLs get you to my-vmware in places that indicate you do not have a license.

This seems to be the only link that consistently gets you the license and downloads:

For instance, the ones below with

Chocolatey: vcredist 2005/2008/2010 updates succeeding again after Microsoft rebuilt the installers multiple times causing new hashes each time

Posted by jpluimers on 2021/05/17

Follow-up in my blog post Chocolatey: vcredist 2005/2008/2010 updates failing as Microsoft rebuilt the installers multiple times causing new hashes each time last Friday.

The chocolatey packages have been updated this weekend and work again. Hopefully Microsoft is done and no new updates are needed (:

New versions thanks to [Wayback/] Chocolatey Software | jberezanski!:

ESXi: wrong IPv4 address after moving the ESXi boot USB stick and SSD devices to an identical motherboard with different MAC addresses

Posted by jpluimers on 2021/05/17

A while ago, I wanted to move the ESXi USB stick and SSD devices to another machine with identical motherboard as it had a larger physical case more suited for expansion.

To my surprise, the management network stayed at the same IPv4 address, despite it being being from a DHCP pool, and the new MAC addresses having different IPv4 addresses assigned in the pool (I run a kind of static dynamic address system where the DHCP server has the correct mapping between MAC and IPv4 addresses).

This appears to be a known issue: by default, ESXi copies the MAC address to the vmknic of the management network instead of following hardware changes. You can see this in the screenshot showing the right physical MAC, but the wrong virtual MAC:

The fix is actually quite simple:

After this, you have to perform a reboot for the new setting to take effect.

When booting is done, the virtual MAC has been copied from the physical MAC:

Note I did not have to fiddle with /etc/vmware/esx.conf as VirtuallyVTrue had to.

For more information, see these links (I copied the content of the final link below the footer as it cannot be saved in the WayBack or archives):
