The CentOS 4.8 kernel I have (2.6.9-89.0.16.EL) does not have CONFIG_SCSI_MULTI_LUN set: sauron.deepsoft.com% grep LUN /boot/config-2.6.9-89.0.16.EL CONFIG_PREEMPT_VOLUNTARY=y # Some SCSI devices (e.g. CD jukebox) support multiple LUNs # CONFIG_SCSI_MULTI_LUN is not set But the CentOS 5.5 kernel (-2.6.18-194.26.1.el5) does: sauron.deepsoft.com% grep LUN /boot/config-2.6.18-194.26.1.el5 CONFIG_PREEMPT_VOLUNTARY=y # Some SCSI devices (e.g. CD jukebox) support multiple LUNs CONFIG_SCSI_MULTI_LUN=y > > Anyway > https://access.redhat.com/kb/docs/DOC-3293 > -- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments
