When the scsi_dh_alua handler issues an RTPG during initialization, if it gets
0x06/0x29/0x04 as the sense,
it will fail to attach the handler. NetApp E-Series returns 0x29/0x00 for
power on, and 0x29/0x04 for
conditions that cause the controller to reboot again. These conditions should
be treated identically within
the handler.
