If you change the CHAP or mutual CHAP parameters, they are used for new iSCSI sessions. For existing
sessions, new settings are not used until you log out and login again.
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 host, end the session through the command line, or the storage system forces a logout.
After the session ends, you can no longer connect to targets that require CHAP.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Required privilege: Host.Configuration.Storage Partition Configuration
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.
Configure Advanced Parameters for iSCSI in the vSphere Client
The advanced iSCSI settings control such parameters as header and data digest, ARP redirection, delayed
ACK, and so on. Generally, you do not need to change these settings because your host works with the
assigned predefined values.
CAUTION Do not make any changes to the advanced iSCSI settings unless you are working with the
VMware support team or otherwise have thorough information about the values to provide for the settings.
