That would _immediately_ cause a failback to said group. Which is what a
certain storage vendor also doesn't want. ;-)
If anything, I'd assume a choice of:
a) Reenable "immediately"
b) Reenable after N seconds in which no new failures have been detected
(giving the fabric a delay to stabilize)
c) Reenable manually only.
