Optical Prime can identify and differentiate locally attached disks and disk clusters within individual devices using unique LUN naming IDs and disk serial numbers assigned to disks and any applicable clusters. Sometimes there may be a need to break a cluster disk and list each node as a local disk for its server. This does not affect the disk performance statistics (IOPS, latency, throughput).
This article describes how to destroy a cluster disk using a Live Optics project.
Prerequisite
You must have a Live Optics project created from one or more collector runs.
- Open the Live Optics web portal at https://app.liveoptics.com/home/.
- Select a project from your Recent Projects, or click All Projects on the right aside of the screen to access the full list of completed collections.
- Once the project opens, select the Performance tab on the top left of the screen.
- To destroy a cluster disk from a project, locate and select a cluster disk under Shared Cluster Disks. In the right window, under the details of the selected cluster disk, click Modify Disk.
- Click Destroy Cluster at the bottom of the window.
- Click Yes when prompted for confirmation.
- Once the cluster disk is destroyed, the following confirmation message displays on screen. The destroyed cluster no longer displays in the Shared Cluster Disk list. The disk nodes in the cluster are changed for each server, and the project statistics are recalculated.
