While working on some older DL360’s, I ran into the infamous Purple Screen of Death. Similar to Microsoft’s Blue Screen of Death, this occurs when there is a kernel panic in Linux variants that result in a system halt. This typically is due to a driver issue, hardware issue, or in my case, a recent patch.

The task hung for a few minutes and the... read more.

In an article posted last month, Tim Husar demonstrated how to reset an ILO password on a VMware ESXi host without any downtime. Today, I want to show you a different variation of that process, tailored for an older ILO card operating with an earlier version of ESXi. Since we are using tools that are native on the ESXi HPE custom build, depending on which version you are running, you might need to run different tools.

The Scene Recently, we were working with a client who was experiencing packet loss on some network adapters on their systems. The ESXi host was set up in a pretty standard configuration of a vSwitch with two physical NICs connected to it. We’d done a lot of troubleshooting up to this point and wanted to start correlating Virtual Machines to pNICs. The NIC teaming on the vSwitch was set up as a default active/active scenario and was using the route by origin method. This means that when a VM powers u... read more.

Recently, a client became locked out of the HPE ILO Administrative account on six VMware ESXi hosts. The direct route to fixing this involves downtime, and solutions that could be done while the hosts were online couldn’t be found. We were able to review the HPE REST API documentation and resolve the issue by following the steps below. The HPE ESXi must have been installed or updated with the VMware Custom HPE Software.
