I'd like to follow up on that point. Because until recently, I always said the same thing about the Dell PERC, and I learned there's a gray area. I bet there is for you too. If you create a hardware mirror, and one disk dies, you can simply toss another disk into the failed slot, and it will auto-resilver. No need to kick it. If you create a raid-5 or raid-6, same is true. No need to kick it. If you have a hotspare ... and the hotspare gets consumed ... then you slap a new disk into its place, and it will not automatically become a new hotspare. If you have a single disk raid-0 or raid-1, and it dies, you replace it, and it will not automatically become a new raid-0 or raid-1. You need to kick it. I don't know what the HP equivalent is, but in a Dell, using PERC, you use the MegaCLI utility to monitor the health of your HBA. Yes, it is a pain. In a Sun, it varies based on which specific system, but they have a similar thing. Some GUI utility to monitor and reconfigure the HBA. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
