Hi there,

is it possible to rescan the scsi bus on linux and to get devices which
were not connected before boot. I need a scsi command or a c funktion
or an ioctl or something like this!

Greez, Kai

Hello Kai,

Take a look at the rescan-scsi-bus.sh script on the following page:
http://www.garloff.de/kurt/linux/scsidev/

BTW, I sent you private e-mail a while ago about SCSI pass-through 
libraries, did it arrive at all?

THX, I found this already. Seems to be not that easy to do this under
linux. What do you think about the scsidev tool? I tried to understand
the code, but yet I don't.

I suspect the scsiadd source at http://llg.cubic.org/tools/ would point you
in the right direction.

        We had a server with HOT swap drives but no PERC controller,
so we had the following notes on how to remove/add a scsi drive.  This
may give you some ideas.


################### TO REMOVE DRIVE

echo "scsi remove-single-device 0 1 2 3" > /proc/scsi/scsi
(replace "0 1 2 3" with your "Host Channel Id Lun")

-- for us:
(SU-recover1)/var/log>cat /proc/scsi/scsi
Attached devices: 
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: FUJITSU  Model: MAS3184NC        Rev: 5B08

--- want to remove the first seagate, after disabling in slot

echo "scsi remove-single-device 0 0 3 0" > /proc/scsi/scsi

############## TO RESTART
After you replace the drive and restart it

echo "scsi add-single-device 0 1 2 3" > /proc/scsi/scsi
