LUN 0 didn't show up according to your log output and comments below.

The adapter seems to think there is a target and lun 0.

Did anything show up on host 1?

Yep.

The 0x10000 is a DID_NO_CONNECT, generally the adapter can't talk to
the target at all.

It seem like the storage was seen, then went away and then came back.

Do you always get the same behaviour?

Are there other messages in your log? Just post the entire log without
the scsi logging on, from adapter load time to scan completion.

You can also use:

	echo "- - -" > /sys/class/scsi_host/host0/scan
