The Cluster Node Details page displays information about a selected cluster node and allows removal of that node from the cluster.
Navigate to Home > Server Settings > Cluster Configuration, select a node, and click details to display its Cluster Node Details page.


Field/Item Description
Cluster Node Name The cluster node name (label).
Cluster Node ID The ID assigned to the node.
Status The status of the SMU.
Network & Storage
File Systems The overall status of the file systems:
  • OK. All file systems up and operational.
  • Failed. One or more file systems has failed.

Click the status link to display the File Systems page, which lists all file systems assigned to the EVS in that cluster node.

Ethernet Aggregations The status of the Ethernet aggregations in the cluster node:
  • OK. All aggregated ports are up and linked.
  • Degraded. One or more ports in an aggregation has failed.
  • Failed. All ports in an aggregation have failed.

Click the status link to display the Link Aggregation page, which lists all aggregations in the cluster node.

Management Network (HNAS server only) The overall status of the management network:
  • OK. Links are up and heartbeats are being received.
  • Failed. No heartbeats are being received, and the links may be up or down.

Click the status link to display the Ethernet Statistics page, which lists information about the management port and the aggregated Ethernet ports in the cluster node.

Fibre Channel Connections (HNAS server only) The status of the Fibre Channel ports in the cluster node:
  • OK. All ports up and operational.
  • Degraded. Some ports up and operational, but one or more has failed.
  • Failed. All ports have failed.

Click the status link to display the Fibre Channel Statistics Per Port page, which lists all Fibre Channel ports in use in the cluster node.

Cluster Communication This status of communications within the cluster node.
Cluster Interconnect:
  • OK. Link is up and heartbeats are being received.
  • Standby port down. The primary link is up and heartbeats are being received, but the secondary link is down.
  • Link up, no heartbeating. At least one link is up, but no heartbeats are being received.
  • Link down. All links are down (and therefore no heartbeats are being received).
Management Network:
  • OK. Both links are up and heartbeats are being received.
  • Link up, no heartbeating. Both links are up, but no heartbeats are being received.
  • Link down. Both links are down (and therefore no heartbeats are being received).
Quorum Device (HNAS server only):
  • OK. The Quorum Device is communicating with the cluster node.
  • Link up, no quorum communication. The link to the Quorum Device is up, but the Quorum Device is not communicating with the cluster node.
  • Link down. There is no communication with the Quorum Device.
Note: The Quorum Device is internal on the NAS module, so Quorum management is automatic.
Chassis (HNAS server only)
Power Supply Status The status of the cluster power supply units (PSUs):
  • OK. Both PSUs are installed and operating normally.
  • Not Fitted. One PSU not responding to queries, which may mean that has been removed from the chassis, or is not properly installed in the chassis.
  • Fault or Switched Off. One PSU not responding to queries, and it has failed, been switched off, or is not plugged in to mains power.
  • Unknown. One PSU not responding to queries, and the exact cause cannot be determined.
Temperature The status of the temperature in the cluster node chassis:
  • OK. Within the normal operating range.
  • Degraded. Above normal, but not yet critical.
  • Failed. Critical.

When available, the temperature in the chassis is also displayed. The displayed temperature is the highest reported temperature of any of the boards in the chassis.

Chassis Disks The status of the server's internal hard disks, and the percentage of the server's internal disk space that has been used:
  • OK. Operating normally.
  • Degraded. A non-critical problem has been discovered with one or both of the server's internal hard disks.
  • Failed. A critical problem has been discovered with one or both of the server's internal hard disks.
Chassis Battery Status (not applicable to Series 5000) The status of the server's battery pack.

When the indicator is green:

  • OK. Capacity and voltage within the normal operating range.
  • Initialising. PSU battery is initializing after initial installation.
  • Normal Charging. PSU battery is being charged.
  • Cell-Testing. PSU battery is being tested.

When the indicator is amber:

  • Discharged. Capacity and/or voltage below normal. This status should be considered a warning; if it continues, the PSU battery should be replaced.
  • Low. Capacity or voltage below normal operating level. This status should be considered a warning; if it continues, the PSU battery should be replaced.
  • Not Responding. PSU battery is not responding to queries.

When the indicator is red:

  • Fault. PSU battery is not holding a charge, has the wrong voltage, or some other fault, and the PSU battery should be replaced.
  • Not Fitted. PSU battery is not detected. Contact your technical support representative for more information.
  • Failed. Capacity and voltage consistently below acceptable minimum, or the PSU battery is not charging, or is not responding to queries. This status indicates a failure; the PSU battery should be replaced.
  • Very Low. Capacity and voltage below acceptable minimum. If this status continues for more than a few hours, it indicates a failure; the PSU battery should be replaced.

When available, the level of the battery charge also is displayed.

Fan Speed The status of the fans in the cluster node chassis:
  • OK. All fans operating normally.
  • Degraded. One or more fans spinning below normal range.
  • Failed. At least one fan has stopped completely, or is not reporting status.

When available, the chassis fan speed is also displayed. The displayed fan speed is the slowest reported speed of any of the three fans. An error message may be displayed, even if it does not correspond with the slowest fan.

System Uptime The duration since the last reboot of the cluster node.
System (NAS module only)
System LUs The status of the server’s logical units and the percentage of the internal disk space that has been used. The Maximum Used value refers to the partition that is using the most space.
System Uptime The duration since the last reboot of the cluster node.
EVS The names (labels) and status of the EVSs assigned to the node:
  • Green. Online and operational.
  • Amber. Offline, but listed here because it is hosting the administrative EVS.
  • Red. Failed.

Click the EVS name to display the EVS Details page for that EVS.

remove (HNAS server only) Removes the node from the cluster.
