[CLUE-Tech] RedHat Kickstart, with Oracle and EMC.

Jim, Thanks for the reply. We're doing a little something different
here. What we are attempting to do is install a Media Manager server on
Linux for NetBackup. We have a Brocade switch fabric network with HP
Storage Libraries and HP-UX Media Manager servers. The HBA isn't
directly connected to the libraries so we're throwing domains, WWNN
(Worldwide Node Names), tape drives and controllers into the mix.

Interesting you mention that the SAN volume must show up at LUN0 and be
consecutive after that, perhaps that's the problem we're running into,
"not scanning past LUN0". We also don't have any management software to
do LUN masking or anything else spiffy. I've included the last email
message from QLogic that addresses the SCSI mid-layer and their driver
(BIOS v1.81, driver version 6.04.00 Beta 8) running on RH 8.0:

Hello,

We have looked at your debug driver messages and have the following
details to share with you:

1) The qla2200 module sees all 7 target devices and sends a report LUNs
to each of them; returned from your devices are the LUN count as you can
see below:

qla2x00_build_fcport_list(): Found matching port 011000, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e00221e0e6, loop id = 0x0081
lun_discovery(1): fcport lun count=3, fcport= f7f54a80
qla2x00_build_fcport_list(): Found matching port 011100, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e00221e0e7, loop id = 0x0082
lun_discovery(1): fcport lun count=4, fcport= f7f54b00
qla2x00_build_fcport_list(): Found matching port 011200, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e00221d9fd, loop id = 0x0083
lun_discovery(1): fcport lun count=3, fcport= f7f54b80
qla2x00_build_fcport_list(): Found matching port 011300, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e00221da67, loop id = 0x0084
lun_discovery(1): fcport lun count=4, fcport= f7f54c00
qla2x00_build_fcport_list(): Found matching port 021000, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e002222c6b, loop id = 0x0089
lun_discovery(1): fcport lun count=3, fcport= f7f54c80
qla2x00_build_fcport_list(): Found matching port 021100, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e002222c70, loop id = 0x008a
lun_discovery(1): fcport lun count=4, fcport= f7f54d00
qla2x00_build_fcport_list(): Found matching port 021400, device flags=
0x1
qla2x00_build_fcport_list(): Port returned +++  (port_name) ->
100000e002223a31, loop id = 0x008c
lun_discovery(1): fcport lun count=3, fcport= f7f54d80

2) The Linux SCSI mid layer does not find the following targets and is
not scanning past LUN 0:

Attached scsi tape st0 at scsi1, channel 0, id 0, lun 0
Attached scsi tape st1 at scsi1, channel 0, id 2, lun 0
Attached scsi tape st2 at scsi1, channel 0, id 4, lun 0
Attached scsi tape st3 at scsi1, channel 0, id 6, lun 0

**	**	**

We can see that our driver is properly scanning and reporting the
devices you have attached to our HBA; however, the Linux SCSI mid layer
is not scanning your devices properly. This is a problem for which we
have no solution, and at this juncture, we can only suggest that you
contact Red Hat for input, and share with them the details we've
discussed.
