Look in /proc/scsi/scsi for the vendor and model and add them into the device_list array in scsi_scan.c ... {"", "", "*", BLIST_SPARSELUN}, If you don't configure lun 0, you may have to use BLIST_FORCELUN which if my understanding is correct will force scanning of all luns. I hear there is some REPORT_LUNS code that will eliminate the need to do this, although don't know which kernel has it. ~mc On 06/08/02 19:27, manjuanth n wrote: >Dear sir, > we have SAN environment with hitachi storage box >and brocade switch. we are trying to install Linux >with qlogic HBA card. we are facing strange >problems >1.
