Did you try replacing the patch-cables and/or SFPs on the path between servers and disks, or at least cleaning them? A speck of dust (or, God forbid, a pixel of body fat from a fingerprint) caught between the two optic cable cutoffs might cause any kind of signal weirdness from time to time... and lead to improper packets of that optic protocol.
Are there switch stats on whether it has seen media errors? //Jim _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
