Scsi Disk - Removable media problems

Scsi Disk - Removable media problems

[Mark Hounschell]

I have 2 IOMEGA BETA90 scsi drives connected to an Adaptec pci 2930c scsi 
adapter. I use these drives in their raw form vi the SG interface. I cannot boot 
successfully with these drives connected and no media installed (2.6.24.3). 
After the machine finally boots up, "lsscsi" does not even show them. I'm 
booting off Sata drives and the scsi controller is NOT in the initrd. When the 
media is installed all is good BTW.

I tried "options scsi_mod dev_flags=IOMEGA:BETA90:0x1000" in my modprobe.conf 
file and then I get devices via lsscsi shown at the end which is pretty much 
useless though, I think.


partial dmesg output:

Obviously you can't do a successful Read Capacity command to a disk with no media???

Then lsscsi:

[6:0:5:0]    disk    IOMEGA   BETA90            1.5  /dev/.tmp-8-32

What can I try??

Thanks in advance
