Storage requirements
Your environment must meet persistent storage requirements for WebSphere Automation.
Storage requirements
Ensure that your Red Hat®
OpenShift® Container Platform cluster has a supported persistent storage in an encrypted persistent volume. By
default, the product installation uses dynamic storage provisioning. The product database requires
ReadWriteOnce
access mode. The security components require more storage with
ReadWriteMany
access mode. The health components also require separate storage with
ReadWriteMany
access mode. The Platform UI requires ReadWriteMany
access mode.
The default storage settings are valid for most scenarios. However, if your storage configuration requires different permissions or other settings, see WebSphereAutomation custom resource for options. For health-specific storage configuration, see WebSphereHealth custom resource.
When you configure health-specific storage, encrypt the file system where investigations are stored to protect sensitive information about your servers. Encryption is important if your WebSphere Application Server or WebSphere Application Server Liberty servers use Java™ HotSpot VM because WebSphere Automation collects hprof files to analyze memory leaks.
Ensure that the cluster is configured with a default storage class that satisfies the requirements, otherwise specify the StorageClass name in the custom resource. For more information on setting up the default storage class, see Changing the default storage class in the Red Hat OpenShift Container Platform documentation.
Use one of the persistent storage options for your Red Hat OpenShift Container Platform cluster.
