We've had a Fuji M2372K disk hooked up to a xylogics 753 for our Sun 3/160 for several months. I'm trying to add a second disk to the controller. I've daisy-chained the disks, so it's Sun<->old-disk<->new-disk. Everything's hooked up and works sort-of okay, but there's a couple of things that are bothering me. First, while formatting it (under SunOS instead of MUNIX!!!), "format" complained that the disk wasn't set up for sector slipping. I didn't find anything in the Fuji or Xylogics documentation on how to set that up. (I formatted the first Fuji disk as part of the SunOS 4 installation, and I don't recall anything peculiar back then.) What am I doing wrong? Anyway, I managed to get the disk formatted and newfs'd, and when I use it, I run into the second problem. I tried to copy about 100 Megabytes of files to the new disk with: tar cf - <old-partition> | (cd <new-partition> ; tar xfBp -) and the system froze. Froze, that is, except for the copying of files. Aside: This reminded me of when I was formatting it. "Format" told me it would take 12 minutes to format the drive. It sure did, and _nothing_, other than the format, took place during those 12 minutes. (Such terminals responding, screensaver waking up...) After 12 minutes, everything resumed pretty much as normal. Anyway, when I tried to tar the files over to the new partition, several megabytes copied, and then the system evidently crashed. (It's hard to tell the difference between a frozen system and a crashed system.) I'm hoping that this freeze-out is not the standard mode of operation for two disks on a Xy 753. Perhaps someone can tell me that I'm doing something wrong and how to fix it. Otherwise, it looks like we just wasted several thousand dollars. Thanks in advance. Brian H.
