Hi,
"Thanks a bunch..though it worked for this time, i need information on how to find the dev file names given channel ID Lun information"
Please see
http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/ for more than you possible wanted to know about SCSI. Specifically,
http://www.tldp.org/HOWTO/SCSI-2.4-HOWTO/dnames.html shows that sdX is scsi Disk, scX is scsi Cdrom, stX is scsi Tape, etc. Now, since USB Jumpdrive is consider a disk (seems easy after the fact don't it), we look at the info you gave us:
"scsibus2:
2,0,0 200) 'LEXAR ' 'JUMPDRIVE PRO ' '0 ' Removable Disk"
So, sdA is taken by your raid drive on your scsibus1, so scsibus2, has to be sdB had to be next, hence, your answer. It is too bad there is not one place to found out about what you asked, but it does cover alot, USB, SCSI, logs, mounts, etc.
My 'dmesg' output told me where my Jumpdrive was:
usb_control/bulk_msg: timeout
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: LEXAR Model: JUMPDRIVE PRO Rev: 0
Type: Direct-Access ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0

sda: Write Protect is off
/dev/scsi/host1/bus0/target0/lun0: p1
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 4
USB Mass Storage support registered.
And my /var/log/messages had this:
Aug 7 00:31:49 localhost kernel: usb_control/bulk_msg: timeout
Aug 7 00:31:49 localhost kernel: scsi1 : SCSI emulation for USB Mass Storage devices

So, my jumpdrive above being scsi1, it was sda, and since it's the first partition, sda1.
I bought a jumpdrive this week, just so I could play with it. I'm going to 'fdisk' it, and make two vfat partitions on it, just to be sure I can mount sda1 and sda2, Gee, the fun never stops. Of course, the next step is to 'only' have encrypted files on it, so I can 'lose' it by accident, but not worry about data theft.
