>Description:

I have a iscsi target where I can log in and get a new scsibus attached, but
no devices. Using "iscsictl report_luns" answers "No LUNs!".
Forcing "scsictl scsibus0 scan 0 1" makes an sd disk attach:
sd0 at scsibus0 target 0 lun 1: <NAS, iSCSI-VDISK, 0> disk fixed

>How-To-Repeat:
No idea, works with other targets.

>Fix:
I will have a look, but can't dig right now, filing as a reminder.
