How to initiate a rescan of the scsi bus und linux? |
|
|
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!

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
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: SEAGATE Model: ST336753LC Rev: 0006
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 05 Lun: 00
Vendor: SEAGATE Model: ST336753LC Rev: 0006
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: PE/PV Model: 1x6 SCSI BP Rev: 1.1
Type: Processor ANSI SCSI revision: 02
--- 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
