I discovered this while trying to get sound working on my desktop
machine. Basically, a SCSI CD-RW that once worked has simply stopped
working, as far as I can tell.
Details: the SCSI card is:
00:0a.0 SCSI storage controller: LSI Logic / Symbios Logic (formerly
NCR) 53c810 (rev 23)
Subsystem: LSI Logic / Symbios Logic (formerly NCR) 8100S
Flags: bus master, medium devsel, latency 32, IRQ 11
I/O ports at d000 [size=256]
Memory at e2000000 (32-bit, non-prefetchable) [size=256]
Capabilities: [40] Power Management version 1
and the CD-RW is an HP CD-Writer:
joehill:/dev# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: IOMEGA Model: ZIP 100 Rev: E.03
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: HP Model: CD-Writer+ 9200 Rev: 1.0c
Type: CD-ROM ANSI SCSI revision: 04
I have used it before, both for writing and reading, on this machine so I
know it works adequately. But I can't mount:
joehill:/dev# mount /dev/cdrom /cdrom
mount: /dev/cdrom is not a valid block device
joehill:/dev# mount /dev/scd0 /cdrom
mount: /dev/scd0 is not a valid block device
joehill:/dev# mount /dev/sr0 /cdrom/
mount: /dev/sr0 is not a valid block device
joehill:/dev# mount /dev/sr1 /cdrom/
mount: /dev/sr1 is not a valid block device
Two questions:
1.) The small question: how can I tell what device (/dev/*) a given SCSI
device is attached to?
2.) The big question: what should I do to diagnose this?
Thanks.
