Hi all, ? I'm having an issue getting my installation of FreeBSD to detect all the drives in the system. It has 48 total, 46 2TB, and 2 250GB. The system consists of six controllers, with eight drives on each. The two 250GB hard drives are the first drives on controllers 0 and 1. ? There are two of these machines with the exact same configurations, having the same problem. A very odd thing is that every time the systems are rebooted, the drives that go undetected vary. Also, when the systems were full of 250GB drives, all were detected. All drives are detected in the BIOS of the controllers, just not by FreeBSD. Any and all help is greatly appreciated.

Staggered spin-up means they're not all coming up quickly enough? With a rig as complex as that, I'd boot up another OS, like Linux or Windows and see if they can see all the drives. - Mark

It had stretched downwards with time until it shorted some pins on the disk controller on side where they were soldered. -- _ _ // \\// Eivind Evensen \/
