[Techtalk] RHEL AS 3.0 U4 not recognizing LUNs on EMC Clarion with QLogic QLA2300 card, Dell 6630 server

[Caitlyn Martin]

Hi, everyone,

Talk about things beyond my expertise or the scope of
my job...  Oh well... there are some real experts here
:)

I have three Dell 6650 servers with QLogic QLA2300
cards running Red Hat Enterprise Linux 3 Advanced
Server, Update 4 plus all the latest and greatest
errata.  The OS is seeing the QLogic card and seeing
the various LUNs but not presenting them as drives
that can be used.  In other words I cannot partition
or make a filesystem.

/proc/scsi/qla2300/1 shows all the LUNs but only shows
one registered to the OS.  Here is the full contents
of the file:

Anyone on list significantly more clueful than I am?

Any help will be gratefully appreciated.
