So I think rescanning should occur in the kernel automatically after
every
bus reset for every different kind of peripheral bus. Every
peripheral bus,
even parallel SCSI, I think has a bus reset: parallel SCSI, FC, 1394
- yes,
ATA - ?, others - ?
[Venkat] Bus reset is a very costly operation in SCSI. After doing a
SCSI BUS RESET all devices go to UNIT ATTENTION . All the devices need to
cleared from this condition. So in order to detect new devices are we going
to do a SCSI BUS RESET every now and then??? Since SCSI dos not support
target initiated event notification, we have no choice left. Some kernel
thread or a user daemon can initiate a bus scanning.
