Hi all,
Thanks for your responses to my earlier question about swapping small disks for larger ones. Looks like we're going to have to get the mice in the comms room to pedal faster...
Anyway, another query entirely. I've just found that one of my netapps is really poorly wired - it's a 3040C with two SATA shelves on one loop, and most of the wiring has IN and OUT ports swapped from the way it should be, aside from one example where it's the right way around. The netapp head can see the shelves though, so it's clearly not too much of a problem.
I now want to add two more shelves to the loop. Is it worth recabling the whole thing so it's done correctly, bearing in mind that vol0 lives on the affected SATA shelves and there is production stuff on the other loop (FCAL shelves), I'm guessing the filer won't like it if vol0 goes away? Someone here suggested that the incorrect wiring may be affecting performance. Or does it make no difference and I can just add the new shelves with the wiring inthe same backwards manner?
