The current CentOS 5 kernel (CentOS 5.5: 2.6.18-194.26.1.el5) has multiple LUN support enabled (this is the stock kernel): 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 Upgrading to 5.5 is probably a good idea anyway. > > Thank you > > Abe > > ********************************************************************** > This email and any files transmitted with it are confidential and > intended solely for the use of the individual or entity to whom they > are addressed.
