When you use EMC CLARiiON or Invista arrays for storage, the hosts must register with the arrays. ESX/ESXi
Performs automatic host registration by sending the host’s name and IP address to the array. If you prefer to
perform manual registration by using storage management software, turn off the ESX/ESXi auto-registration feature.
1 In the vSphere Client, select the host in the inventory panel.
2 Click the Configuration tab and select Advanced Settings under Software.
3 Select Disk in the left panel and scroll down to Disk.EnableNaviReg on the right.
4 Change the default value to 0.
5 Reboot the host for the changes to take effect.
This action disables the automatic host registration enabled by default.
