Importing a cluster topology
Import the topology of a DataStax Enterprise cluster that already exists and is being monitored in OpsCenter into Lifecycle Manager so you can start centrally managing installations and configurations.
Import the topology of a DataStax Enterprise (DSE) cluster that already exists in OpsCenter and is being monitored in OpsCenter into Lifecycle Manager (LCM) so you can start centrally managing configurations. LCM imports the cluster topology and automatically builds the topology model in the Clusters workspace. If a cluster is not connected to OpsCenter, the cluster is not displayed in LCM and is not available for import.
Additionally, LCM currently only supports importing DSE clusters installed from Debian (.deb) or RedHat (.rpm) packages.
Prerequisites
- Add SSH credentials.
- Ensure all nodes in the cluster you want to import use the same SSH credentials.
- Only the GossipingPropertyFileSnitch is supported for managing or importing DataStax Enterprise clusters in Lifecycle Manager. See Migrating from the PropertyFileSnitch to the GossipingPropertyFileSnitch.
- Lifecycle Manager currently does not support configuring nodes by network
interface (
listen_interface
orrpc_interface
/native_transport_interface
). If a cluster is configured with those options, the import will fail. Reconfigure the nodes by listen_address and native_transport_address rather than the corresponding interface options before importing the cluster. - Datacenters must consist of a homogeneous node workload type. Mixed-load datacenters cannot be imported into Lifecycle Manager.
- If Transparent Data Encryption is enabled, it must be disabled prior to importing the cluster into LCM. See Encrypting configuration file properties.
Procedure
What's next
- Create the necessary configuration profiles and associate them with the cluster, datacenter, or nodes in the Clusters workspace.
- Add a repository and associate it with the cluster in the Clusters workspace for running future install jobs.
