Long, long ago the default failure mode for failed writes was panic.
This was changed for several years ago with the introduction of the
"failmode" property. Since ZFS is ported to Solaris 10, perhaps the
failmode property is not available until you upgrade? To see:
zpool get all poolname
If there is no failmode property, then upgrade.
