Last summer, our F540 failed, and we moved our data to an F740. Two days later, the system crashed everytime it hit 51% of a disk-rebuild. Ultimately, it was determined that the onboard FC-AL controller was bad and the system board was replaced with one from a slightly older F740. We've been fine ever since. NetApp sent us a PCI FC-AL card, "just in case", but it's still in the box, unused.
Having followed the "AW: 'Loop break detected' followed by failover" thread, and noted that people seem to be using the PCI adapters now, instead of the onboard adapters, and that apparently NetApp is shipping them with the PCI adapter standard now, I'm in a quandry.
Should I proactively install the PCI adapter and switch to it, or should I leave well enough alone? Can someone at NetApp comment on this and give me some guidance?
