Hi,
Does the hardware sym53c8xx_2 works with support removing and adding
devices?
When using sym53c8xx_2 if we find storage, remove the device using the
sysfs/proc interface, then physically remove the device, everything goes
well. However, if we physically plug the disk back in and try to readd
it through the sysfs/proc scanning interfaces, it looks like
scsi_scan.c's inquiry will time out. This causes the sym error handler
to run, which works great and we end up doing a BUS RESET (BDR failed so
we got escalated), and after that the inqiury is retried and we find the
device and it works fine.
Is the inquiry timing out expected? Does the hardware even support
hotplug? Or does it support it partially support it (support it with
some help), and we are we supposed to be manually resetting the bus,
with something like a sg_reset, after we have physically plug the disk
back in?
Thanks for any info,
Mike
