Subject: rebuild kernel or get new hard drive?

Drop it to single user mode before trying to umount your filesystems and do
the fscks.

Possibly some of your rootvg partitions - like /usr and /var are on the
ones you are trying to umount, and since they are part of the kernl mounts,
a simple umount won't unmount them.

I highly recommend staying away from the "lazy" umount command - "umount
-l /filesystem".

You can go to single user mode by typing "init 1" of course that makes the
machine completely unavailable.
