CD juke box Date: Tue, 09 Jul 1996 13:58:35 GMT Organization: OzEmail Pty Ltd - Australia Lines: 33 Message-ID: <4rtrtq$i18@reader1.reader.news.ozemail.net> NNTP-Posting-Host: 203.15.163.195 X-Newsreader: Forte Free Agent 1.0.82 Given that: [ 1 ] I have just obtained the Walnut Creek FreeBSD 2.1 cdrom [ 2 ] Reading the hardware.txt file indicates that my Adaptec AHA -2842A SCSI card should have a kernel driver [ ahc1 ] included to control it. [ 3 ] My CD ROM device is a Pioneer DRM 624X 6 disk, quad speed jukebox The question is.... Does the driver know about the SCSI logical unit numbers ( LUN's ) that are used to control the individual disks in the jukebox?? The SCSI address of the jukebox is device #3 and the disks are accessed as follows: disk 1 ---- device #3, LUN #0 disk 2 ---- device #3, LUN #1 disk 3 ---- device #3, LUN #2 etc., etc., .... Being an ex-CROMIX pilot, I am hoping that some easy form of [ major_number : minor_number ] addressing is possible. Note: I have not yet installed FreeBSD as I am still reading doco ... (WHAT someone who reads that stuff!!!) and also have some projects in progress under that single user program launcher that most of the worlds PC's appear to be infested with. cheers /mjt
