Re: Onstat question

Bringing online down and up is not a solution, because the "problem" you have is kinda random. I had the same one, and I called the tech support. The message "Changing data structure..." is due to concurrent access to shared memory. I.E., onstat -u reads data from the shared memory, but has a lower priority than online, which changes its shared memory entries when it wants. So, don't worry about it, it's just an annoying message not an error one ;-) BTW, don't write shell scripts that rely on onstat's output... Cheers.
