This error indicates that you are attempting to use an invalid combination of initiator and target credentials for iSCSI authentication.

You can view the set of credentials that iPXE is using with the ''show'' command:

    iPXE> show username
    username:string = mcb30
    iPXE> show password:hex
    password:hex = 64:72:65:61:6d:20:6f:6e
    
    iPXE> show reverse-username
    Could not find "reverse-username"
    iPXE> show reverse-password:hex
    Could not find "reverse-password"

Things to try:

  * If you are using initiator (forward) authentication, check that you have specified both ''username'' and ''password''.

  * If you are using target (mutual) authentication, check that you have specified all four of ''username'', ''password'', ''reverse-username'', and ''reverse-password''.

Note that you cannot use target authentication without also providing credentials for initiator authentication, since this is not permitted by the iSCSI protocol.
