What about posting ESXi version ?<br />
Do you see same alert in iLO? Does it come back after you clear iLO logs?<br />
To call hp support:<br />
Update firmware: <a href="https://www.google.com/search?q=spp_2014.02.0" rel="ugc">https://www.google.com/search?q=spp_2014.02.0</a>&nbsp;<br />
Then run full insight diagnostics saving report on USB<br />
Do you see same defect?<br />
Yes - call HP<br />
No - consult vmware hcl for recommended driver levels

Nothing is in the ILO.<br />
<br />
Does this suggest an issue within VMware?

It seems to be a bug in vmware and/or HP customisation agents<br />
So you have vsphere update manager on vcenter to comfortably install all applicable updates?

I've logged a ticket with VMWare and waiting for them to get back to me.<br />
<br />
It's the first time I've logged a ticket with them and I have to say they are pathetically slow.

Sorry for the delay. &nbsp;The server isnt in the same location as me. &nbsp;So in the interest of fairness I've closed the ticket.<br />
<br />
many thanks

One of our ESX servers has a temperature alert.<br />
<br />
Any ideas what this means. &nbsp;To the untrained eye it looks like it's a faulty sensor as I dont think it can be -20<br />

ESX:  Temperature Alert

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

VMware

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
