We are doing mirroring with the MVS version 1 server.  Our DB
is currently 400 mb and divided into 4 volumes (plus 4 mirrors,
of course).

We are running the MVS server; our DB is about 900M, on
four primary "volumes" mirrored to four secondary "volumes".
All the primaries are kinda scattered around, the mirrors are
all on one volume.

We lost a disk drive containing one of the primaries once,
ADSM moved over to the mirror with no hitch.
