Sun > used LSI chips extensively, presumably oracle still does. Just wanted to follow up on this thread. Soon after I sent this we installed nexenta core. The system has been up for 13 days. We have scrubbed all 5 of the 9-disk pools at least twice, with no hiccups. Clearly the mpt driver (or something else with the combo of freebsd, zfs, and this hardware) still needs some help. I'm not highly motivated to spend a bunch of time reproducing this issue for debugging, especially for a driver for such an old card. That said, does anyone know if the mpt code was used as a base for other drivers? If so it might be worth putting in the effort. thanks, danno -- Dan Pritts, Sr. Systems Engineer Internet2 office: +1-734-352-4953 | mobile: +1-734-834-7224
