Solaris Express packages on S10

A number of people in the field have been applying Solaris Express (nevada) packages against Solaris 10 to get iSCSI. I don't think this is officially supported by Sun? I'm still trying to figure that out. Most people doing this are hitting the following problem on sparc.

WARNING: iscsi driver unable to online iqn.1986-03.com.sun:01:00093d12170c.434c5250.vol0 lun 0

What this really means is the associated target driver is not configured or is failing its attach(). Those sneaky customers out there applying express packages against S10 will see this 100% of the time on sparc. The problem is not with the iSCSI software. Your missing a /etc/driver_aliases entry. You need to ensure you have the following driver_alias entry to cause the iSCSI logical unit to bind to the target driver. This entry states that a class scsi device with INQUIRY Device Type of 00 (Disk) should bind to the target driver sd (Disk Driver).

sd "scsiclass,00"

You can find more details on driver_aliases in its manpage.

If you apply a full Solaris Nevada install or use official S10 patches to get iSCSI this will not occur. We add the entry for you. As a final note, Beware stability levels are different between Solaris Express and official S10 patches. Solaris Express is the bleeding edge, similar to downloading code from opensolaris.org building it and installing it on your machine.
