First, is there a reason you're using forcetakeover rather than just cf
takeover? The later should do the trick.
Second, in my experience, takeover time is much quicker certainly under
2 minutes, and in many case under 1.
(Giveback is usually longer than takeover).
But it looks like you don't have your IP takeovers set up properly
which could be causing delays. In your current config, I'd be surprised
if any of your hosts could see the
downed filer.

Subject: filer fail over times
How long should it take a filer to fail over from one head to another?
When I force a failover (cf forcetakeover) from one head the other goes
down for minutes. Here's what I see on the console. This is a new filer
with very little traffic going to it and FC is not even set up yet, all
NFS/CIFS.
array01> cf forcetakeover
cf forcetakeover may lead to data corruption; really force a takeover?
yes
