This operation updates the Challenge-Handshake Authentication Protocol (CHAP) credentials for a specified iSCSI target. By default, a gateway does not have CHAP enabled; however, for added security, you might use it.
IMPORTANT: When you update CHAP credentials, all existing connections on the target are closed and initiators must reconnect with the new credentials.
