2. When testing server crash, the second virtual IP resources (**secvip_HN1_HDB03**) and Azure load balancer port resource (**secnc_HN1_HDB03**) will run on the primary server alongside the primary virtual IP resources. While the secondary server is down, the applications that are connected to the read-enabled HANA database will connect to the primary HANA database. The behavior is expected - it allows applications that are connected to the read-enabled HANA database to operate, while a secondary server is unavailable.
