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 10...

[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,

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 ke...

[PATCH] hw/virtio-scsi: Set max_target=0 during vhost-scsi operation
From: Nicholas Bellinger <nab at linux-iscsi.org> This QEMU patch sets VirtIOSCSIConfig->max_target=0 for vhost-scsi operation to restrict virtio-scsi LLD guest scanning to max_id=0 (a single target ID instance) when connected to individual tcm_vhost endpoints as requested by Paolo. This ensures that virtio-scsi LLD only attempts to scan target IDs up to VIRTIO_SCSI_MAX_TARGET when

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: mkin...

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 [root at host qlogic]# cat /proc/scsi/qla2xxx/1 <snip> SCS...
