As far as my (limited) vinum knowledge goes, you really don't need to do a
resetconfig.

Vinum writes the configuration to the disk and reads the information from it.
I think it will be able to cope with a missing disk by itself because the
label on it has not changed; on what is now /dev/ad1s1h vinum has stored
the fact that this vinum drive is labeled 'a', and even if the freebsd
device node changes names, vinum will still know that the then /dev/ad0s1h
is labeled 'a'.

Unfortunately this is only my understanding and I haven't yet needed to
do such an operation for real. YMMV.
