This can also be accomplished by using the vCenter GUI.
From the vCenter GUI on the ESX host navigate to Configuration -> Storage Adapters. Select the iSCSI
Software Adapter and click Properties.
Under the General tab click the Configure button. Place a check mark in Enabled and hit Ok. This will
enable the iSCSI initiator and assign a unique iqn to the ESX host. Administrators familiar with enabling
iSCSI in ESX 3.5 will notice that the firewall policies are automatically set when you enable it in vSphere4.
