Hello, I went through the multipath code and found there was hardware handler for specified hardware, such as emc. When init path, it will use the trespass command given by the handler. Does this mean it only support the A/PF mode of array? When SCSI commands, such as SCSI PR, are sent to a disabled path, will trespass be triggered?
