    DKIOCINFO is the macro for the ioctl that gets info from a disk:
    http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/sys/dkio.h#166

    I am not a COMSTAR expert but I believe your warning is coming from here:
    http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/io/comstar/lu/stmf_sbd/sbd.c#1581

    It looks like COMSTAR was trying to query one of the zvols, and
    failed.  This is almost assuredly a consequence of the hung pool.
