The lldd_dev_found CB is where you should set the itct, and it is
only possible to do that if you report the device gone first. So that
seems like a simpler solution.
Sure, something like that - you just need to get libsas to trigger the
proper hw port id assignment for the device. As for specific
implementation in the LLDD, that up to you guys.
Thank you for your suggestions. The disk was finally restored to normal,
but the error handling took a long time. Since the error handling would
set the host to the recovery state, other disks on the same host would
be blocked for a long time. Log as follow:
