Creating a storage cluster

Use this procedure to create a storage cluster.

Before you begin

Make sure that you have the following prerequisites:

  1. Bare Metal worker nodes with visible and attached shared Logical Unit Numbers (LUNs).
  2. Install the IBM Fusion Access for SAN operator. For more information about the procedure, see Installing IBM Fusion Access for SAN operator.
  3. Create the FusionAccess CR in the ibm-fusion-access namespace. For more information about the procedure, see Creating the FusionAccess custom resource (CR).

About this task

After you installed the IBM Fusion Access for SAN operator, you can create a storage cluster with shared storage nodes. The wizard to create the storage cluster in the OpenShift® Container Platform web console provides easy-to-follow steps and lists the relevant worker nodes with shared disks.

Procedure

  1. Log in to the OpenShift Container Platform web console.
  2. Go to Storage > Fusion Access for SAN.
  3. Click Create storage cluster.
  4. Select the worker nodes that have shared LUNs.
    Note: You can select only worker nodes with a minimum of 20 GB of RAM from the list.
  5. Click Create storage cluster.
    The page reloads, opening the Fusion Access for SAN page for the new storage cluster.
