So sparse lun scanning is working then - sounds like your missing luns
is a problem with your array configuration as the kernel is probing them
(if it is was creating the even ones) - means the qlogic driver must
not be able to see these luns. Not familiar with your array so can't
help any more - your array vendor would probably be the most help.

Seems so. The odd thing is, that the hba1, vs. hba0, is not listed as
seeing any LUNs just existing. I'll go back and re-check my config. My
DSL really sux ATM, so doing things through X sessions has been a bit
painful.
