Comment 3 for bug 1771989

Hi Eric.
One reason is when the initiator node has bugs in its implementation and doesn't handle CHAP correctly. The operator may not want to, but they may have to disable CHAP in such circumstances. It is certainly a reasonable argument but I think it is better applied to what the default value of the option should be, rather than whether the option should be there or not.
Also, the option is supported by a large number of the current volume drivers. I don't see why LVM should be the exception to this.
