[opensuse] rescan-scsi-bus.sh outdated?
All, I've been doing some config changes on our FC-SAN, and tried using rescan-scsi-bus.sh to pick up the changes - without much luck. I started digging through the script, and it seems to me that the check for return codes from sg_turs in testonline() is not correct. I'm tempted to open a report on that. Has anyone here used rescan-scsi-bus recently? Is there some other tool that should be used instead? /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I would think this happens automatically with udev. I know that in some systems I have with removable media, the devices are detected without intervention. I do have a udev rule to make some devices show up as certain symlinks in /dev. But that is still only after the devices have been detected. To see what is currently connected, use lsscsi. Maybe you will be surprised and see your devices automatically. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

OK, tried that, and it doesn't show the correct output. I've removed 6 LUNs, but they still appear.

To answer my own question - yes, rescan-scsi-bus is way outdated. I retrieved the latest version from http://www.garloff.de/kurt/linux/ Which worked just fine. (for devices removed anyway).

Adding devics worked fine too. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
