MAX_LUNS SIZE LIMIT ON RHEL 3.0 and 4.0
Dear List Users-
IHAC planning storage layout and is looking for the following MAX_LUNS
size limit on RHEL 3.0 and 4.0. Details are below. Customer database
size is estimated to grow to 5 TB and worries that they will not be able
to present enough devices to the system if used with EMC powerpath and
RHEL 3.0 max_lun limitations. I have advised on using OCFS or ASM as
this is a 1...

[PATCH 0/2] virtio-scsi fixes for 3.6
James,
patch 1 fixes scanning of LUNs whose number is greater than 255. QEMU
passes a max_lun of 16383 (because it uses SAM numbering) but in Linux
it must become 32768 (because LUNs above 255 are "relocated" to 16640).
Patch 2 is a resubmission of the patch for online resizing of virtio-scsi
LUNs, which needs to be rebased.
LUNs above 255 now work for all of scanning, hotplug, h...

Multi-Card reader (SD, MMC, etc) and CONFIG_SCSI_MULTI_LUN kernel option in 34.0.2. Workaround
...//www.cs.sfu.ca/~ggbaker/personal/cf-linux)
that CONFIG_SCSI_MULTI_LUN should be enabled on kernel (=Y) but current
34.0.2 doesn't have it enabled by default, is there any particular
reason to not be enabled?
By the other hand i've also tweak the /etc/grub.conf file to boot the
kernel with max_luns=32 and results are the same, only scsc lun=0 is
recognized.
At the same time using the workaround mentioned in the link pasted b4
regarding to modify the /etc/modules.conf to include 'options scsi_mod
max_scsi_luns=8' gives the same results, no detection at all for the
card slots.

HP SureStore 40x6e - Multiple LUN's problem on CentOS 4.4
...H910
Type: Sequential-Access ANSI SCSI revision: 02
I read somewhere that this shouldn't be a problem with RHEL 4, but I
can't seem to get it detected. I tried to add
options scsi_mod max_scsi_luns=6
to modprobe.conf and regenerated initrd - no change. Tried adding
max_luns=6 max_report_luns=6
to the kernel line in grub.conf, no change. I tried to manually add it
by doing:
echo "scsi add-single-device 0 0 5 1" > /proc/scsi/scsi
but again, no change.
Any suggestions? Am I on the right track and just doing something
wrong? I know recompiling the k...

USB multi-card reader working, finally took the time
A thread on multi-cards 2 months ago, gave me a hint on how to get usb
multi-card readers working:
Quoting "J.J. Garcia" <stigmatedbrain at gmail.com>:
"Have you tried putting it into /etc/modprobe.conf (options scsi_mod
max_luns=32) and rebuilding initrd image after that? That's the way I
was doing it so far, and it always worked for me. "
So I then had to learn how to rebuild initrd image. Turns out that is
mkinitrd (duh :-[ ).
So I added to my /etc/modprobe.conf:
options scsi_mod max_luns=8
Then:

Sparse LUN's
...sue, and indeed here:
http://filedownloads.qlogic.com/files/driver/48437/README_qla2xxx2-6U4.htm#BlacklistEntries
Apparently, I should be able to add a line to modprobe.conf that allows
sparse LUNs. So I followed the instructions and added
options scsi_mod dev_flags="SUN:CSM200_R:0x040" max_luns=20
and rebuilt initrd. This doesn't seem to work, as only LUN 0 is
configured by the OS despite LUN 9 also being unmasked.
I've also tried
options scsi_mod default_dev_flags=0x040 max_luns=20
in modprobe.conf with no luck
