odd behaviour of app writes to mirrored volumes

Hi,
Normally, I setup my volumes under Solaris (doesnt matter, 8 or 10),
as vxassist -g dg01 -U gen make vol01 500m dg0101, then I do a mirror
vxassist -g dg01 mirror vol01 dg0102.

Which is legal and does work, however, when the primary dg01 array (or simply in this case, the volume) disappears for some reason, the app does not seem to continue to write to the mirror and fails (this is oracle RAC) or if vol01 picks up a bad sector, the mirror write fails on the other side (dg0102).
The arrays are on San switches and are multipathed. Is my mirroring wrong?
