      description: <p>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. This operation is supported in the volume and tape gateway types.</p> <important> <p>When you update CHAP credentials, all existing connections on the target are closed and initiators must reconnect with the new credentials.</p> </important>
