Hi Mike,
Thanks for suggestions
I think you meant,
echo 1 /sys/block/sdX/device/delete
I don't see /sys/block/sdX/device/remove in my setup.
I'm not sure: Is it echo offline /sys/block/sdX/device/state, echo
scsi
remove-single-device ${host} ${channel} ${id} ${lun} /proc/scsi/scsi, or
echo 1
/sys/class/scsi_device/${host}:${channel}:${id}:${lun}/device/delete
?
To delete a device just do
echo 1 /sys/block/sdX/device/delete
I think the confusing thing is that you don't see a delete in
/sys/block/sdX/device.
You can also do it through proc if it is enabled for your kernel.
No need to offline the device before deleting. The scsi layer will
handle the device state transitions.

I think depending on the kernel config options used the device symlink might not even be there. -- You received this message because you are subscribed to the Google Groups open-iscsi group.
