ECS 3.6.1 Administration Guide
View node and disk health
The Node & Data Disks panel displays the health status of disks and nodes.
A green check mark beside the node or disk number indicates the number of nodes or disks in good health. A red x indicates bad health. Click Node & Data Disks to see more hardware health metrics. If the number of bad disks or nodes is a number other than zero, clicking the count takes you to the corresponding Hardware Health tab (Offline Data Disks or Offline Nodes) on the System Health page.
NOTE
- If the data from failed disks have already recovered and failed disks are ready for replacement, they will not show in the Node & Data Disks panel. Click Manage Disks under System Health to go to Maintenance, which indicates if there are disks that are ready for physical replacement. Alternatively, access Maintenance using left panel menu, .
- The maximum number of connections per node is 1000.
