Certain storage arrays require that ESXi hosts register with the arrays. ESXi performs automatic host registration by sending the host's name and IP address to the array. If you prefer to perform manual registration using storage management software, disable the ESXi auto-registration feature.
- Browse to the host in the vSphere Web Client navigator.
- Click the Configure tab.
- Under System, click Advanced System Settings.
- Under Advanced System Settings, select the Disk.EnableNaviReg parameter and click the Edit icon.
- Change the value to 0.
This operation disables the automatic host registration that is enabled by default.
