New Revision: 272409
URL: https://svnweb.freebsd.org/changeset/base/272409
Log:
Use REPORT LUNS command for SPC-2 devices with LUN 0 disconnected.
SPC-2 tells REPORT LUNS shall be supported by devices supporting LUNs other
then LUN 0. If we see LUN 0 disconnected, guess there may be others, and
so REPORT LUNS shall be supported.
