Manage clusters

Contributors netapp-dbagwell amgrissino

You can edit a cluster running Element software, manage SSH configuration, set protection domain monitoring, and shut down a cluster.

What you’ll need
  • At least one cluster must be added.

    You must add at least one cluster to use NetApp Element Management extension point functions.
  • Current full Cluster Admin user credentials for the cluster.

  • Firewall rules enable open network communication between the vCenter and the cluster MVIP on TCP ports 443 and 8443.

View cluster details

  1. Select NetApp Element Configuration > Clusters.

Edit a cluster profile

You can change the cluster User ID and password from the NetApp Element Configuration extension point.

This procedure describes how to change the cluster admin user name and password used by the plug-in. You cannot change the cluster admin credentials from the plug-in. For instructions on changing credentials for a cluster administrator account, see the NetApp SolidFire and Element Documentation Center - Managing cluster administrator user accounts.
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Edit.

  5. Change any of the following:

    • User ID: The cluster administrator name.

    • Password: The cluster administrator password.

      You cannot change the IP address or FQDN of a cluster after a cluster is added. You also cannot change the assigned Linked Mode vCenter Server for an added cluster. To change the cluster address or associated vCenter Server, you must remove the cluster and add it again.
  6. Select OK.

Remove a cluster profile

You can remove the profile of a cluster that you no longer want to manage from the vCenter Plug-in using the NetApp Element Configuration extension point.

If you set up a Linked Mode group and want to reassign a cluster to another vCenter Server, you can remove the cluster profile and add it again with a different linked vCenter Server IP.

  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster you want to remove.

  3. Select Actions.

  4. Select Remove.

  5. Confirm the action.

Enable Encryption at Rest

You can manually enable encryption at rest (EAR) functionality using the NetApp Element Configuration extension point.

This feature is unavailable in SolidFire Enterprise SDS clusters.
Steps
  1. Select NetApp Element Configuration > Clusters.

  2. Select the cluster on which you want to enable encryption at rest.

  3. Select Actions.

  4. In the resulting menu, click Enable EAR.

  5. Confirm the action.

Disable Encryption at Rest

You can manually disable encryption at rest (EAR) functionality using the NetApp Element Configuration extension point.

Steps
  1. Select NetApp Element Configuration > Clusters.

  2. Select the check box for the cluster.

  3. Click Actions.

  4. In the resulting menu, click Disable EAR.

  5. Confirm the action.

Enable SSH

You can manually enable a Secure Shell (SSH) session using the NetApp Element Configuration extension point. Enabling SSH allows NetApp technical support engineers access to storage nodes for troubleshooting for the duration you determine.

This feature is unavailable in SolidFire Enterprise SDS clusters.
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Enable SSH.

  5. Enter a duration for the SSH session to be enabled in hours up to a maximum of 720.

    To continue, you need to enter a value.
  6. Select Yes.

Change the SSH time limit

You can enter a new duration for an SSH session.

This feature is unavailable in SolidFire Enterprise SDS clusters.
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Change SSH.

    The dialog box displays the remaining time for the SSH session.

  5. Enter a new duration for the SSH session in hours up to a maximum of 720.

    To continue, you need to enter a value.
  6. Select Yes.

Disable SSH

You can manually disable Secure Shell (SSH) access to nodes in the storage cluster using the NetApp Element Configuration extension point.

This feature is unavailable in SolidFire Enterprise SDS clusters.
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Disable SSH.

  5. Select Yes.

Set protection domain monitoring

You can manually enable protection domain monitoring using the NetApp Element Configuration extension point. You can select a protection domain threshold based on node or chassis domains.

What you’ll need
  • The selected cluster must be monitored by Element 11.0 or later to use protection domain monitoring; otherwise, protection domain functions are not available.

  • Your cluster must have more than two nodes to use the protection domains feature. Compatibility with two-node clusters is not available.

Steps
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Set Protection Domain Monitoring.

  5. Select a failure threshold:

    • Node: The threshold beyond which a cluster can no longer provide uninterrupted data during hardware failures at the node level. The node threshold is the system default.

    • Chassis: The threshold beyond which a cluster can no longer provide uninterrupted data during hardware failures at the chassis level.

  6. Select OK.

After you have set monitoring preferences, you can monitor protection domains from the Reporting tab of the NetApp Element Management extension point.

Shut down a cluster

You can manually shut down all active nodes in a storage cluster using the NetApp Element Configuration extension point.

If you want to restart rather than shut down the cluster, you can select all nodes from the Cluster page in the NetApp Element Management extension point and perform a restart.

This feature is unavailable in SolidFire Enterprise SDS clusters.
What you’ll need

You have stopped I/O and disconnected all iSCSI sessions.

Steps
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Shutdown.

  5. Confirm the action.

Expand your NetApp HCI infrastructure

You can manually expand your NetApp HCI infrastructure by adding nodes using NetApp HCI. A link to a NetApp HCI UI for scaling your system is provided from the NetApp Element extension point. Additional links are provided within the NetApp Element Management extension point from the Getting Started and Cluster pages.

This feature is unavailable in SolidFire Enterprise SDS clusters.
Steps
  1. Select NetApp Element Configuration > Clusters.

  2. Check the cluster.

  3. Select Actions.

  4. Select Expand your NetApp HCI.
