You will probably get various suggestions here.  One that would work
is to shutdown the database servers on the XP system until you are
able to upgrade it.  You're not actually gaining much by running the
databases on both servers, since neither server will run without the
other being up.  (1 vote out of 2 does not make a quorum.)  If you
drop back to just 1 database server then at least that server can
run in the absence of the other.  (1 vote out of 1 does make a quorum.)

Not true.
Whatever server has the lowest IP address listed in the CellServDB will get an extra half vote. This means in a cell with an even number of database servers partitioned exactly in half (or with half down), the group containing the lowest host will be able to achieve quorum.


Also, the ptserver and vlserver have been able for quite a long time (at least since 3.3a, and I think rather longer than that) to serve read-only data in the absence of a quorum.

So, if your higher-numbered server goes down, you still get to do everything. If the lower-numbered server goes down, you can't make changes, but you can still look up volume locations and protection information.

Also, in a two-server configuration, only the lower-numbered server needs to be upgraded in order to resolve the quorum problem. If this is your Linux box, then you win -- upgrade it, and leave the XP box alone. If the lower-numbered server is the XP box, then you will need to either shut down its database servers (and remove them from CellServDB), or obtain the binary fixes from IBM, if they are available.
