• In utils diagnose test output, the components that matter for replication are validate_network, ntp_reachability and ntp_stratum, and all three should show Passed. in context
• Unified CM database replication is a fully meshed topology in which the publisher and every subscriber connect logically to every other server in the cluster. in context
• The health-check technote shows a healthy runtimestate output as a completed status check with no errors or mismatches found, DB/RPC/DbMon of Y/Y/Y for every server, a replication queue typically at 0, and Setup Completed for every server. in context
• The hosts, rhosts and sqlhosts files must match across all nodes in the cluster, and their equivalence is shown in the Unified CM Database Status report in Cisco Unified Reporting. in context
• In utils ntp status, the publisher shows itself synchronized to an external NTP server, and subscribers show the publisher as their NTP source at one stratum level higher. in context
• The health-check technote lists four services that must show STARTED in utils service list for replication: Cluster Manager, A Cisco DB, A Cisco DB Replicator and Cisco Database Layer Monitor. in context
• utils dbreplication status starts a background check of replication, and its progress and result are read with utils dbreplication runtimestate. in context
• The health-check technote reads the system history log for ungraceful shutdowns, which appear as consecutive Boot entries with no Restart entry between them, and suggests rebuilding a server after such an event. in context
