I am running CentOS 3.1 and everything is working beautifully except my HP12000e tape library that requires multi-LUN support. Every time I re-compile the 2.4.21 kernel with the multi-LUN SCSI option, I get the multi-LUN to work but something else breaks. Is there a pre-compiled kernel somewhere that is similar to the stock CentOS kernel except that it includes the multi-LUN feature? thanks!

...he 2.4 kernel but it doesn't seem to work in the 2.6. Any help would be appreciated. Config: Standard intel server board. p4 processor (3) 3-ware controllers Lsi Logic u320 scsi card External SCSI tape library. Worked before on a Whitebox linux 2.4 kernel, just added: options scsi_mod "max_scsi_luns=16" to /etc/modules.conf and rebuilt the initrd image, then reboot. All worked fine. But Whitebox is crap and was giving me probs and also want everything standardized on CentOS! Thanks!

...st: scsi5 Channel: 00 Id: 05 Lun: 00 Vendor: HP Model: C5713A Rev: 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...

...y 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.

I am running CentOS 4.4 and trying to bring up my tape library. When I do cat /proc/scsi/scsi, it shows only the drive and not the changer although both are shown when the Adaptec card initializes. I recall in the distant past that I had to do "something" to get the kernel to properly scan the SCSI bus for the additional LUN but I cannot for the life of me recall what that was. It

Hi, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM
