This means, avoid smartarray stuff P420, P8*, etc at all costs for ZFS until HP allow direct passthrough without the smartarray disconnecting the disk even if there is an issue.As what will happen when a disk starts to fail (but isn't completely borked) is that the smartarray controller will simply disconnect the whole disk. You might think this is the correct thing to do, however if the disk is still functional (on other parts of its surface) then it's still useful to have, especially when re-silvering to a new disk. ZFS can still use a failing disk. It has CRC/etc and can manage this for you. The smart array simply disconnects the whole disk and if you're not on something like raidz3 (or don't scrub regularly) then you could be in for a bad experience when resilvering and you find another disk has an issue in a different area (such is the life using HP SAS)
