Need Real Name

it is a bad idea because it breaks several scsi devices (mostly scanners) In addition to that: this is a runtime option! add options scsi_mod max_scsi_luns=127 to /etc/modules.conf Explanation seems good, resolving as not a bug. I know this is ancient history, but I just hit this issue and a minor comment seems in order. After adding the "options" line to /etc/modules.conf, you'll have to rebuild the initrd and reboot for it to take effect. Rebooting with the old initrd but with the options line changed has no effect. This is a very good point you make. For completeness I record the suggestion that you also need to rebuild initrd because the scsi module is loaded from the ramdisk, possibly because you boot from scsi disks. Folk without scsi boot devices who dont load the scsi module from initrd won't need to do this. Just some additional comments, you can cat commands directly to /proc/scsi/scsi and accomplish this without a reboot... if you are just using some flash card readers, you can always have those commands cat'd in an init script. (see scsi programming howto on ldp for more info). |
