Author: ken Date: Tue Aug 27 19:47:03 2013 New Revision: 254970 URL: http://svnweb.freebsd.org/changeset/base/254970 Log: If a drive returns ASC/ASCQ 0x04,0x11 "Logical unit not ready, notify (enable spinup) required", instead of doing the normal retries, poll for a change in status. We will poll every half second for a minute for the status to change. Hitachi drives (and likely other SAS drives) return that ASC/ASCQ when they are waiting to spin up. What it means is that they are waiting for the SAS expander to send them the SAS NOTIFY (ENABLE SPINUP) primitive. That primitive is the mechanism expanders/enclosures use to sequence drive spinup to avoid overloading power supplies.
