fsck hanging

[John W. Eaton]

I'm running Ultrix 3.1 on a Vaxstation 3200 and have run into a
problem with a new Hitachi DK515C disk and CMD-220/TM controller.

The installation of the controller and the disk seemed to go smoothly.
I can create filesystems on the disk with newfs, mount them, and even
read and write files.  Unfortunately, when I try to run fsck on any
partition, it almost always hangs after displaying the pass 1 message.
When it hangs, I can't kill it and ps displays something like

  1313 p0 D   00:00 fsck /dev/rra2a ...

What could cause fsck to hang, and what makes this (or any) process
impossible to kill?

I set up the kernel configuration file so that ra2 is drive 0 for the
CMD controller.  At boot time, a message is displayed to the console
which indicates that somewhere, something thinks ra2 is an RA82 disk.
Is it possible to partition this disk as an RA82?  If not, does anyone
have a correct disktab entry for a DK515C?

Does anyone else out there have this hardware configuration?  If so,
how did you make it work?

Any help would be greatly appreciated.
