HTTPS

It looks like there are two things you need to modify here in your config:

1. setting the service types to HTTP from TCP on all VIPs/VSs/RSs
2. configure the virtual server VIPs to be defaults

Here is a summary of what you will need to update in the configuration. Keep in mind, you will need to admin-offline these items before being able to change service type.

virtual-server vsSecondary
attach virtual-ip vipSecondary default

virtual-server vsSecondary1 
service http
attach virtual-ip vipsecondary1 default

real-server rss-rep1 
service http

virtual-ip vipsecondary1
service http

virtual-server Webssilo1 
attach virtual-ip vipsweb1 default

Doing this, I was able to replicate your configuration and successfully pass traffic to the original servers and replication servers for both HTTP and HTTPS. This should get you up and running, too.
