As a part of 250 node RHOSO 18 adoption scale testing, The scale team will be using Optimize service host maintenance strategy and zone migration strategy to migrate workloads as a part of post adoption RHEL EDPM node minor update task.

It will be useful for any customers who has multiple compute nodes and want to migrate workloads from compute nodes before performing maintenance.

Currently users needs to run nova live migration manually and disable the node. Then perform the RHEL EDPM node minor update.

OpenStack Optimize service host maintenance strategy and Zone migration strategy(Both the strategy are supported from RHOSO-18 FR4 release) will help users to migrate workloads from multiple compute nodes in one go.

Documenting/Referencing these two strategies as a procedure for preparing compute nodes for EDPM compute node minor updates post adoption tasks will help the customer. 

Requirements (mandatory -_ Complete while in Refinement status):
A list of specific needs, capabilities, or objectives that a Feature must deliver to satisfy the Feature. Some requirements will be flagged as MVP. If an MVP gets shifted, the Feature shifts. If a non MVP requirement slips, it does not shift the feature.

Done - Acceptance Criteria (mandatory - Complete while in Refinement status):
Acceptance Criteria articulates and defines the value proposition - what is required to meet the goal and intent of this Feature. The Acceptance Criteria provides a detailed definition of scope and the expected outcomes - from a users point of view
…

Below are the deliverables from this initiative:

• A component job performing post adoption from RHEL-9.4 to RHEL-9.6
  • It will use zone migration and host maintenance strategy to prepare compute node for RHEL EDPM compute node minor update process
• Watcher doc update linking both strategies under compute migration heading
• Post adoption tasks doc update mentioning  watcher docs as a procedure for migrating compute nodes procedure under post adoption tasks.

Use Cases - i.e. User Experience & Workflow: (Initial completion while in Refinement status):
Include use case diagrams, main success scenarios, alternative flow scenarios.
