What can I do to speed up the process of fixing this bug? Many thanks in advance, Johnny Well, here seems to be a fix: https://www.linux-community.de/Neues/story?storyid=14588 it is written german, but the most interesting thing is written in C ;-) It seems, that drivers/scsi/scsi_devinfo.c needs to be patched. 143 {"EMULEX", "MD21/S2 ESDI", NULL, BLIST_SINGLELUN}, 144 {"easyRAID", "16P", NULL, BLIST_NOREPORTLUN}, 145 {"easyRAID", "X6P", NULL, BLIST_NOREPORTLUN}, 146 {"easyRAID", "F8", NULL, BLIST_NOREPORTLUN}, 147 {"FSC", "CentricStor", "*", BLIST_SPARSELUN | BLIST_LARGELUN Could you please apply this patch, as it seems to fix the problem? Many thanks in advance, Johnny The patch needs to be revised. Thanks. I queued this in -mm as scsi-blacklist-the-easyraid-f8-ide2scsi-adaptor.patch for the scsi people to consider. It would be useful if you could confirm that this fix still works and is still needed in current kernels, thanks. Patch is in 2.6.23-rc. |
Most recent kernel where this bug did not occur: 2.6.13.5 Distribution: gentoo amd64/2005.0 Hardware Environment: Tyan S2882 onboard Adaptec AIC7902 easyRAID F8 IDE2SCSI adaptor Software Environment: Problem Description: The EasyRAID F8 IDE2SCSI adaptor is reporting too many luns and is not accessible. Steps to reproduce: boot kernel 2.6.14 with an easyRaid F8. I think the problem is related to the domain validation in the U320 SCSI spec, and maybe a bios bug in the easyraid F8.
