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.

No, it is the other way around, actually! This error comes from the target system, not the system that crashed, that was the intitiator system. The underlying device IS a zvol on the target system!
So the question I ask myself, since I saw this error, is if this could be a/the problem that caused the lu/pool on the initiator system to go off line? Though there were also the loop offline  msg on the initiator:

root at omni:/var/log# dmesg | grep qlc
Oct  2 18:33:08 omni qlc: [ID 439991 kern.info] NOTICE: Qlogic qlc(0,0): Loop OFFLINE

And what puzzles me is the multipath messages, because there is no multipath devices on the system:
