The alarm "Contact lost to secondary SpectroSERVER on host <hostname> port 0xbeef at precedence 20 from primary SpectroSERVER on host <hostname> port 0xbeef." is happening consistently daily.
Spectrum Online Backup shuts down the secondary SpectroSERVER when an online backup occurs.
The secondary server is shutdown during an online backup. This is due to how we load the database on the secondary after an online backup occurs.
This is functioning as designed up to 10.3.2.
Broadcom is looking to change this feature in future releases and having the secondary "pause" just like the primary does rather than shutdown.
