Red Hat Bugzilla – Bug 10088
Only LUN 0 is seen on each if my HBA's

I have two qlogic 2100 fibre channel adapters connected to a Mylex Raid
Controller fibre channel expansion unit. When I create arrays LINUX only
ever detects the array assigned LUN 0 on each HBA. Does LINUX support
Yes, multiple-LUN support exists.
Option 1) recompile kernel with multiple LUN support
Option 2) add a parameter to the boot commandline (through LILO)
- I can't find the parameter documented anywhere, though.
BTW: best way I've found to update the kernel under RH6.2 is to install the
kernel-2.2.16-3.src.rpm, extract with 'rpm -bp', then go modify the config file
that corresponds to whichever version you'll be using (i686-smp, for example),
then go back and use 'rpm -bb' to rebuild the RPM(s). [Warning: takes a long
time, because it builds eight(?) versions of the kernel]
