Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Description of problem: With the advent of fibre channel storage and such it would be cool if you could change the value of CONFIG_SD_EXTRA_DEVS in the default kernels, so that people with larger storage setups will work "out of the box" (one of the great things about RHL, actually). Without this, users are limited to only 40 SCSI devices on the machine, and require custom built kernels to get things working. Set CONFIG_SD_EXTRA_DEVS=128 (the default is 40) This is true in RHL 7.x and 8.0. All the other settings necessary for proper fibre channel support (the setting of CONFIG_SCSI_MULTI_LUN=y) can be done as a runtime/modules.conf option. Thank you! Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Attach 45 SCSI devices (LUNs on a fibre channel disk array, etc.). 2.Reboot -- only the first 40 get sd names (/dev/sdXX). 3.Change it in the kernel, reboot, it works. :-) Additional info:
