Hi,
Dont have bug to disable iSCSI. To enable you dont need reboot, but to disable you´ll need reboot. This is a correct procedure.
vSphere Documentation Center
Prerequisites
Required privilege:
Procedure
| Log in to the vSphere Client, and select a host from the inventory panel. |
2 | Click the Configuration tab and click Storage Adapters in the Hardware panel. |
3 | Select the software iSCSI adapter from the list of storage adapters and click Properties. |
4 | Click Configure. |
5 | To disable the adapter, deselect Enabled and click OK. |
6 | Reboot the host. After reboot, the adapter no longer appears on the list of storage adapters. |
The status indicates that the adapter is disabled.
Note
If you disable the adapter that is used for software iSCSI boot, the adapter is reenabled each time you boot the host.
