Hi,
Looked at this and verified that the allow_restart flag of scsi_debug
devices (disks ?) is usually 0 and when the scsi_debug module is
started with allow_restart=1 then the allow_restart flag does indeed
change to 1. For example:
# cat /sys/class/scsi_disk/1\:0\:0\:0/allow_restart
1
That ASC/ASCQ code means: "Logical unit not ready, initializing command
required" according to my library. Played around with sg_start but didn't
see any change in how it reacts. According to scsi_device.h that flag's
description is: "issue START_UNIT in error handler" which implies it
changes how the EH handler reacts.
Perhaps the 3 line patch description could say a little more about how
to use this new parameter...
