Sorry I was being sloppy. I meant in general 'related to ipv6'. At this point, I think I'm going to just disable ipv6 on the OI entirely. It's a SAN that is internal to my network only, so I can't see any upside to leaving ipv6 on...

Actually, that sounds like a completely different problem, unrelated to name services. That sounds like IPv6 breakage. Depending on the drivers involved, I remember there being various hardware checksum offload bugs that can cause all sorts of strange-looking problems. Some were IPv6-specific. It might be worthwhile to try rebooting with this in /etc/system: set ip:dohwcksum=0 and, if you're using e1000g, this in /kernel/drv/e1000g.conf: tx_hcksum_enable=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0; lso_enable=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0; I don't trust hardware offload schemes any further than I can throw them. For a minuscule bump in performance, they extract many hours and days of wasted administrative effort. -- James Carlson 42.703N 71.076W <carls...@workingcode.com> _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
