Can you set the qlog-lvl to 0x80000077 to get more debug informations. -Tim > Thanks, > Eugene > -- > This message posted from opensolaris.org > ------------------------------------------------------------------------ > > _______________________________________________ > storage-discuss mailing list > [email protected] > http://mail.opensolaris.org/mailman/listinfo/storage-discuss _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
