Some of the older drivers didn't like one version of the StorageWorks container, but did work in another, and we spent the rest of the night scrounging for parts off other containers for the right disk container. :)
Is that right. I just plugged in a brand spanking new spare (well it's been on the shelf for a while) into a 330's shelf and the disk was not detected even after several tries (a defective spare?). I pop a different disk in and it is detected immediately. I wonder whether that was the problem, whether the shelf is becomming flakey, oe whether it was simply a bad spare.
This was some time back. Specifically, DEC DSP3210S drives (the 2 GB narrow drives) only worked in DEC StorageWorks containers which had serial numbers that started with 41, 42, or 43 when placed in the narrow slots on a wide shelf. Newer containers probably work as well; I seem to recall the ones that didn't were numbered starting in the 30s. I don't think Netapp ever sold such drives in those containers so this is unlikely to be your problem unless you had an old drive you stuffed into a old container, and even then, I think the problem only cropped up when you used it in a wide shelf. I could be wrong about that part, though.
If you have looked inside the old DEC carriers, there was a little chip on the internal ribbon that connected the internal drive to the external back connecter. The chip configuration was visibly different between the ones with the older serial numbers (the serial number ON THE CARRIER, mind you) and the newer ones. (I'm presuming the higher numbers were more recent models, which was our reasoned assumption at the time.)
