The NSX Application Platform persistent data storage retains the data collected and generated by the NSX Application Platform even when the platform is offline. You can increase the persistent volume of the data storage used by the NSX Application Platform as the storage needs of the platform services increase.

The system will generate an alarm for the Data Storage core service if it has crossed the threshold value.

Important:

You cannot request to increase the data storage using a volume size that is smaller than what was specified in the last failed request to increase the data storage. You can only specify a volume size that is equal or larger than the last requested volume size. If your new request uses a smaller volume size, the system will use the previously requested volume size again to process your request.

Prerequisites

  • You must have Enterprise Admin privileges.

  • Ensure that the cluster nodes that the NSX Application Platform uses are in a healthy state and that no open alarms exist.

  • Obtain from your infrastructure administrator the number of available disk pools and verify the current limit of the data storage volume. If necessary, request for an increase in the number of disks used by your TKC or upstream Kubernetes cluster nodes.

  • Ensure that the TKC or upstream Kubernetes cluster that the NSX Application Platform uses support volume resizing. If the cluster does not support volume expansion, work with your infrastructure administrator to enable volume expansion. Without volume resizing support, the scale-up operation can fail, but it will not affect the existing cluster that the NSX Application Platform is already using.

Procedure

  1. From your browser, log in with Enterprise Admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Navigate to System > NSX Application Platform and click Core Services.
  3. In the bottom-left corner of the Data Storage section, click Manage Data Storage.
  4. In the Manage Data Storage dialog box, enter the new data storage value.

    This value is the number of available disk pools that you obtained from your infrastructure administrator.

  5. Click Update.

    The system proceeds to update the volume size of each persistent storage used by the NSX Application Platform core services.
