{}USER STORY:{}

As an OpenShift Developer I want to create an enhancement document detailing the operational procedures and necessary API changes for adding a separate disk to Azure OpenShift nodes specifically for etcd data storage so that etcd is isolated from other workloads.

{}Nice to have:{}

{}ACCEPTANCE CRITERIA:{}

• The enhancement document includes a detailed explanation of the hardware requirements for the additional disk (e.g., size, type – SSD recommended). 
• The document outlines the specific steps involved in provisioning the disk within the Azure OpenShift node.
• The document clearly identifies all relevant Azure OpenShift API calls or commands required for the provisioning process (e.g., Azure Disk Resource Creation, Node Configuration updates).
• The document includes troubleshooting steps for common issues that might arise during the provisioning process.
• The document includes a diagram or visual representation of the proposed architecture, showing the etcd cluster and the new disk.
