From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; H010818; .NET CLR 1.0.3705) Description of problem: The default kernel (-3smp at least) does not enable scan_all_scsi_luns, which typically causes only 1 SAN drive to be detected. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Attach system to SAN disks (IBM ESS Shark) 2.Boot/Load module to scan for disks 3.Only 1 disk is detected Actual Results: System detects only the disk an LUN 0 Expected Results: Expected to detect all attached disks, (100 in this cas, with LUNS from 0 to 99) Additional info: Solved problem by building custom kernel with this option available. If this can be turned on by default with causing other problems, you should probably do so, if not, then including SAN enabled kernels to install when FC cards are detected would be good.
Definitely kernel, not kernelcfg (kernelcfg was a GUI tool in older releases to edit /etc/modules.conf). Reassigning to kernel component. Read ya, Phil
1) This option is off by default because it often crashes (cheaper) scsi devices 2) There is a whitelist of devices that are scanned regardless of the option, it seems yours is missing, please send cat /proc/scsi/scsi output 3) This option is a boot time option, no need to recompile your kernel, it's just a line to /etc/modules.conf....
This raises a number of questions: a) I attached the dump below (running a custom built version of 2.4.18-5), however it only seems to list he "Model"; seems it would be better to automaticly key the scan off the existance of a FC device, such as the Qlogic 2x00 card (qla2200.o in my case) b) modinfo qla2200 filename: /lib/modules/2.4.18-5jfs/kernel/drivers/addon/qla2200/qla2200.o description: <none> author: <none> license: "GPL" parm: ql2xopts string parm: ql2xmaxqdepth int parm: ConfigRequired int parm: recoveryTime int parm: failbackTime int parm: MaxPathsPerDevice int parm: MaxRetriesPerPath int parm: MaxRetriesPerIo int # modinfo sd_mod filename: /lib/modules/2.4.18-5jfs/kernel/drivers/scsi/sd_mod.o description: <none> author: <none> license: "GPL" So what option should I pass through the modules.conf c) I did try appending "scan_all_scsi_luns" both at the LILO prompt and in lilo.conf, neither worked.(a suggestion from googlegroups) Attached devices: Host: scsi0
