Configuring Mutual CHAP Authentication on the Storage Array The initiator secret must be unique for each host server that connects to the storage array and must not be the same as the target CHAP secret. Change the initiator authentication settings in the Change Target Authentication window. Use these options to change the settings: • None-Select None if you permit no initiator authentication. If you select None, any initiator can access this target. Use this option only if you do not require secure data. However, you can select both None and CHAP at the same time. • CHAP-Select CHAP if you want to enable an initiator that tries to access the target to authenticate using CHAP. Define the CHAP secret only if you want to use mutual CHAP authentication. If you select CHAP, and if no CHAP target secret is defined, an error message appears. Click CHAP Secret to view the Enter CHAP Secret windows. Use this window to define the CHAP secrets. NOTE: To remove a CHAP secret, you must delete the host initiator and re-add it.
