What happens to the access if CHAP is disabled on the ESX Host?

An ESX Server is configured to access an iSCSI target using CHAP
authentication. What happens to the access if CHAP is disabled on the ESX Host?

A.
Access is unaffected until the ESX Server is restarted

B.
Access is removed on the next rescan

C.
Access is unaffected until either the ESX Server or the iSCSI Array are restarted

D.
Access is immediately removed

Explanation:
iSCSI SAN Configuration Guide, page 40.
If you disable CHAP on a system that requires CHAP authentication, existing iSCSI
sessions remain active until you reboot your ESX/ESXi host or the storage system forces
a logout. After the session ends, you can no longer connect to targets that require CHAP.
