We are using a QLogic Sanbox 5200 and XSan MDC Connection Kit, I believe both are apple approved. All of our systems, including the MDC, are now running XSan 1.4, they were at 1.3 during the first crash so we updated, but all systems were at 1.4 during the second two crashes. We had been advised not to update to 1.4 because of the same stability issues you mentioned, but after the first crash we updated everything thinking that was part of the issue.

The MDC never crashed. It has stayed operational durning all three occurences. We have checked the logs on the MDC as well, and not even those logs give us a hint of what is going on. The connected systems do not lose connection with the SAN. The SAN is mounted when the systems go down, and it re-mounts with no problems when the systems are re-booted.

All 5 systems and the MDC are on battery back-up. We have had power hits before where the backups have kicked in and we were able to properly shut everything down. These crashes do not seem to be power related at all, none of the breakers are being tripped, and everything else in the building retains power.

Today is the one week mark from the second crash, fingers are crossed… Thanks for the thoughts on this, I’ll post in the XSan forum today.

I’ve checked the settings on the Server and all the systems and the Engery Saver preferences all look good. All are set to never to put the computers to sleep.
