Re: INI 9400U and Fedora Core 3

I have an AMD Athlon XP 2600+ with the INI 9400u SCSI card. On this card there is only one device attached, a HP DLT4000 tape unit (2 HP DDS-3 tape units are supposed to be added later). In my /var/log/messages file I keep seeing these entries:

An sda entry would mean there is a SCSI drive attached, but there is none. What is meant with sddr09 I have no idea! When I go into the BIOS of the card, it only sees the DLT drive.




What's in /proc/scsi/scsi ?

Hi!

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Sandisk Model: ImageMate SDDR-0 Rev: 0208
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi1 Channel: 00 Id: 02 Lun: 00
Vendor: Quantum Model: DLT4000 Rev: DA97
Type: Sequential-Access ANSI SCSI revision: 02

The SanDisk is actually a USB cardreader.



Fine. The system is checking the write enable status of the SanDisk. Until you put media in it, you'll continue to see those messages. The system treats USB card reader/writer devices as though they were SCSI disks--in this case with removable media.

SCSI tape devices are named "/dev/st0" (ST for "SCSI Tape").  I'll bet
if you do an "mt -f /dev/st0 status", you'll see the tape whirr and get
a status message about the drive and/or media.

Remember, "/dev/sd" = "SCSI Disk", "/dev/st" = "SCSI TAPE", "/dev/sr" =
"SCSI Removable" (CD-ROM/CD-RW/DVD/DVD-RW)

Hi!

I didn't know USB storage was also 'seen' as SCSI, I know that sdx and stx are SCSI units (or SATA units on my other box). But this continuously logging of the checking for media isn't really normal behaviour is it? I had a system with SCSI CD reader and a SCSI writer and I never saw this kind of logging or console messages. Can I turn this logging off?
Besides that, where are the 'sda' lines coming from then?


Kind regards, Angelo
