Error 25 is "ENOTTY", aka. "Inappropriate ioctl for device":

http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/sys/errno.h#77

The error itself comes because while STMF thinks the underlying storage is a zvol, apparently the DKIOCINFO ioctl failed with the above erro:

http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/io/comstar/lu/stmf_sbd/sbd.c#1575

As Eric (who beat me to the punch here) said, it was likely caused by a hung pool.
