Disable CHAP

You can disable CHAP if your storage system does not require it.

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

Procedure

1	Open the CHAP Credentials dialog box.
2	For software and dependent hardware iSCSI adapters, to disable just the mutual CHAP and leave the one-way CHAP, select Do not use CHAP in the Mutual CHAP area.
3	To disable one-way CHAP, select Do not use CHAP in the CHAP area. The mutual CHAP, if set up, automatically turns to Do not use CHAP when you disable the one-way CHAP.
4	Click OK.
