Create Cluster Disk in DPACK

Team DPACK

Overview

The DPACK collector software is able to 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.  In rare instances, DPACK will not be provided the information needed to correctly indentify local versus clustered disks and will list all of the disks as local disks.  This can cause an incorrect capacity reading within the DPACK project.  This issue does not affect the disk performance statistics (IOPS, latency, throughput, etc).

The DPACK web portal has added features that will allow for the management of disk clusters within a DPACK project.  These features should make it easier to repair any incorrect disk associates with a project.

Below are the instructions for both how to create and destroy a cluster disk within a DPACK project.

Prerequisite Information

  • The DPACK project has already been created from one or more DPACK collector runs
  • Access to a DPACK account should already be complete before beginning the following steps.

Create a Cluster Disk

Step 1:  Access Performance View of project

  1. Locate project to view and click on the name at the top
  2. Once the project opens, click on the Performance View tab

Step 2:  Open DPACK Cluster Disk Modal

To create a cluster disk from any local disk listed under a server in a DPACK project, expand an individual server and highlight one of the local disk drives listed underneath.  This will open a modal called, "Modify Disk".

Step 3:  Select local disks and create the cluster disk

To create a cluster disk, select any of the unassigned local disks that you would like to be included in the cluster disk, provide a name for the new cluster disk, and click "Save" at the bottom.

Once the cluster disk has been created, the following message will appear in DPACK.

Step 4:  Review new cluster disk

The newly created cluster disk will now be listed in the "Shared Cluster Disks" list in the DPACK project.  If there are cluster disks listed prior to creating a new cluster disk, the new cluster will be listed at the bottom.
