qla2300 woes 2005-10-24 - By Lee Whatley, Contractor
Back
Hi All,
I recently installed a Qlogic 2300 HBA on a RHEL v3 U6 (2.4.21-37.ELsmp)
system (AMD64). The HBA has two ports and both are directly connected
to a StorageTek D178 array. The D178 is sharing out 6 LUNS.
When I booted the machine for the first time, kudzu recognized the
qla2300 card and modified my modules.conf file to include "alias
scsi_hostadapter3 qla2300". It did not remake the initrd in order to
load the module on boot, so I did that by hand with "mkinitrd -f".
Now when the system boots it loads the qla2300 module and the kernel
sees the HBA and its two ports. No LUNS seem to show up however. Doing
a "cat /proc/scsi/scsi" only shows my locally-attached scsi disks.
Doing a "cat /proc/scsi/qla2300/6 (or 7 for the second port)" outputs
the following:

As you can see there are LUNS shown at the bottom, but the are "not
registered with the OS". Since the OS for some reason isn't
automatically seeing them, I tried installing them manually using "scsi
add-single-device 6 0 0 0" replacing the last 0 with 1-5 and 31 for the
rest of the LUNS. Now the LUNS show up in /proc/scsi/scsi, but as
generic devices (/dev/sg3-sg9) instead of as disk devices. In addition,
/proc/scsi/scsi seems to think that they are printers!
Output of "cat /proc/scsi/scsi":
---local disks removed--

Has anyone ever seen this behavior before? How do I get the OS to see
the disks as disks and not printers? How do I get the OS to
automatically load those LUNS without having to echo anything to /proc?
Any help or insight would be greatly appreciated.
Thanks,
-Lee
