Identifying All CLDB Nodes

Explains how you can identify all the CLDB nodes in an HPE Ezmeral Data Fabric.

Some procedures in this guide require you to find all the container location database (CLDB) nodes in your fabric.

CLDB Nodes in Cloud-Based Fabrics

In AWS, Azure, and GCP deployments of the Data Fabric, ALL nodes are CLDB nodes because fabric creation configures every node as a CLDB node.

CLDB Nodes in On-Premises Fabrics

In an on-premises deployment, not all nodes are necessarily CLDB nodes. To identify if a node is a CLDB node, ssh into the node as root or the Data Fabric admin user, and issue the following command:

maprcli node list -columns svc,ip

A node is a CLDB node if the service list includes cldb as one of the services:

$ maprcli node list -columns svc,ip
hostname              service                                                                                     ip
