Hello!
I have an old DVD-RAM drive I picked up on ebay. It works fine as a
CD-ROM/DVD-ROM, but I can't seem to get it to work as a DVD-RAM. It's
my understanding that it ought to be able to appear as a slow hard disk,
but format or newfs doesn't recognize it as writable. I also tried
Joerg Schilling's cdrecord-prodvd, which correctly identifies it as a
DVD-RAM but refuses to write to it (as per his documentation).
I have tried 4.7GB media both without cartridge and with cartridge
(cartridge bought new, disk never removed, I understand that at least
used to make it read-only). I also tried modifying /kernel/drv/sd.conf
to include lun=1 through 7
name="sd" class="scsi"
target=6 lun=1;
etc. but it didn't make a difference (just made prtconf -v longer). I
did 'boot -r' between each attempt at mucking with drivers. I also
tried installing Joerg Schilling's scg driver with the following scg.conf:
name="scg" class="scsi"
target=6 lun=0;
I get the following in my dmesg when botting with -r:
Oct 14 23:53:41 tiar.home scsi: [ID 193665 kern.info] scg0 at glm0:
target 6 lun 0
Oct 14 23:53:41 tiar.home genunix: [ID 936769 kern.info] scg0 is
/pci@1f,4000/scsi@3/scg@6,0
Oct 14 23:53:41 tiar.home scsi: [ID 193665 kern.info] scg1 at glm1:
target 6 lun 0
Oct 14 23:53:41 tiar.home genunix: [ID 936769 kern.info] scg1 is
/pci@1f,4000/scsi@3,1/scg@6,0
I have no idea what to make of that information.
I would appreciate any pointers. I'm running Solaris 8 on an Ultra 60.
I'd greatly prefer to get this to work on Sol8 but if upgrading to 9 or
10 is required then so be it (so long as I have confidence it'll work).
Scrapping it means I don't get a DVD-RAM, as I can't afford a new
SCSI drive.
I'm attaching below the output of 'cdrecord-prodvd -prcap' and a portion
of 'prtconf -v'.
Please go easy on me; I used to have a clue with Solaris but I do
almost all Linux nowadays so my Solaris is very rusty. I'd
appreciate any responses CC to my email address
(newsryan42@leesburg-geeks.org) but I'll check the NG eventually.
Many thanks in advance!!
