Reset VMware ESXi root password

vmware_vSphere7_graphicThe root account is the only login account to vSphere ESXi. There is no extra account to create a backdoor to logon to vSphere ESXi when the root password is lost. When a vSphere ESXi host is added to a vCenter instance, management of the host is primary done via vCenter. Troubleshooting ESXi is done primarily on the command line via an SSH connection. By default the SSH service is stopped. To start the SSH service you have to access the server via vCenter Host>Configure>System>Services. When you don’t have the root password for the vSphere ESXi host you have to follow the following procedure.

vmworld2021It is that time of the year again to start looking forward to VMworld 2021. Due to the ongoing Covid-19 pandemic VMworld 2021 will again be “fully virtual” again.

You can follow the conference from the luxury of you own chair and desk. Poor your own drink of choice, sit back and relax and take in all the information on VMware latest and greatest from your own home. Because VMworld 2021 will be fully virtual, like last year that will make it easier for people to attend since you don’t need to arrange travel (flight/hotel) to attend VMworld.

vSAN Hybrid / All Flash

vsan-est-2013As a VMware partner we (my employer PQR) conducts VMware Health Checks. To perform a Health Check on a vSphere (or EUC, NSX-T) environment VMware provides a tool to check if the environment matches the VMware best practices. The tool to check if the environment matches the VMware best practices is called the VMware Health Analyzer. The VMware Health Analyzer is a Photon appliance that you install in the client environment. There is also a Windows installed version of the VMware Health Analyzer. My preference is to use the appliance version. I have the appliance also running on my environment, so if I collected data at a customer site I can load this information in my own appliance, this means that I don’t need a connection with the customer to create my Health Check report. Current version of the VMware Health Analyzer is: 5.5.2.0. Next to the VMware Health Analyzer the consultant checking the VMware environment will also use his own knowledge to check the environment and to interpret the data presented by the VMware Health Check Analyzer.
