There is a known issue with using HTTP::redirect from the LB_FAILED event in some LTM versions:
SOL7899: The iRule HTTP::redirect generates an error when it is used within the LB_FAILED event
https://support.f5.com/kb/en-us/solutions/public/7000/800/sol7899.html
Another option might be to configure a fallback host on the HTTP profile. LTM will issue a redirect to the client if no members in the pool are marked up. ahermans' suggestion would allow you to issue a redirect if a single request failed, which may be better for your requirements.
