Author: avg Date: Fri May 26 17:44:47 2017 New Revision: 318962 URL: https://svnweb.freebsd.org/changeset/base/318962 Log: Allow PROBE_SPINUP to fail in CAM ATA transport The motivation for this is two-fold. 1. Some old WD SATA disks may appear as if they need to be spun up when they are already spinning. Those disks would respond with an error to the spin-up request. 2. Even if we really fail to spin up the disk, we still can try to proceed to the subsequent phases. If we fail later on, then no difference. Otherwise we get a chance to communicate with the disk which is better than completely ignoring it, because a user can try to recover the disk.
