Thanks Joel,

Please correct me if i am wrong. I believe no need to create fresh VIP for maintenance. This can be achieve with below iRule.

1) Create maintenance page and import to F5(irule--> iFile)

       when HTTP_REQUEST {
      set ::maintenance_mode [LB::status node 192.168.250.1 session_disabled]
      if { ($::maintenance_mode) } {
             HTTP::respond 200 content [ifile get "/common/maintenance.html"]
             }
        }

2). Add HTML contents itself in irule

        when HTTP_REQUEST {
      set ::maintenance_mode [LB::status node 192.168.250.1 session_disabled]
      if { ($::maintenance_mode) } {
             HTTP::respond 200 content "Maintenance page Sorry! This site is down for maintenance." "Content-Type" "text/html"
      }
}
