even with raid technology I wouldn't mix directory and page space on the
same volume. A directory reference of any sort I think would kill the
paging never-ending-channel program; and vice versa.

If I went this route, the second LPAR would never (well, except in the
situation where the main LPAR was down and things needed to happen) place a
directory online. And putting a directory online would have to trigger the DIAG
3C in the other system somehow. Change of timestamp on a file or some such
flag... Something that the slave LPAR could check, and wouldn't have to update
to keep things straight.
The backup plan would be to have two directories (probably at the head of each LPAR's first paging volume), and have a way to pass the directory from one to the other, probably, again, having the second LPAR look at a common disk for the USER DIRECT and checking timestamps to tell it if an action is necessary.
