Azure Local Multi Rack — Agent Skill by Microsoft

From the author

Plan, deploy, operate, and troubleshoot multi-rack (rack scale) deployments of Azure Local — preintegrated racks scaling to hundreds of machines, built on Network Fabric Controller, Cluster Manager, SAN storage, and managed network fabric. Use for the Microsoft.NetworkCloud and Microsoft.ManagedNetworkFabric control plane. NOT for standard 1-16 node Azure Local, and NOT for rack-aware clusters (two racks as availability zones, up to 8 nodes, synchronous replication) — those are standard scale. WHEN: multi-rack, rack scale Azure Local, aggregation rack, compute rack, Network Fabric Controller, NFC, Cluster Manager, network fabric, isolation domain, az networkcloud, az networkfabric, multi-rack logical network, multi-rack Arc VM.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The azure-local-multi-rack skill provides a structured approach to planning, deploying, and operating large-scale, multi-rack Azure Local environments. Unlike standard deployments, these rack-scale configurations utilize a specialized control plane involving a Network Fabric Controller (NFC) and Cluster Manager. This skill covers the unique requirements for managing preintegrated racks, SAN storage, and managed network fabrics, ensuring users follow the correct procedures for logical networks, Arc VM management, and fabric operations.

What it does

Guides users through planning and deploying rack-scale Azure Local infrastructure.
Provides procedures for managing Arc VMs, images, and storage in a multi-rack environment.
Facilitates configuration of network fabrics, isolation domains, and load balancers.
Supports operational tasks including monitoring, metrics, and serial console access.
Ensures correct usage of specialized Azure CLI extensions for multi-rack control planes.
Distinguishes between multi-rack and standard Azure Local deployment requirements.

When to use it

When deploying or managing rack-scale Azure Local environments with 100+ machines.
When working with preintegrated racks, aggregation racks, and managed network fabrics.
When utilizing the Microsoft.NetworkCloud and Microsoft.ManagedNetworkFabric control planes.
When you need to configure complex networking components like isolation domains or internal load balancers.
When troubleshooting issues specific to multi-rack infrastructure components.

Advantages

Prevents confusion by clearly separating multi-rack procedures from standard Azure Local workflows.
Provides a centralized map to authoritative Microsoft Learn documentation for preview features.
Promotes safe operations by requiring read-only verification before executing fabric or SAN changes.
Ensures the correct CLI extensions are identified and used for specific resource providers.

Usage examples

“How do I create a new logical network for my multi-rack deployment?”: The agent will guide you through the specific multi-rack logical network creation workflow, ensuring you use the correct network fabric commands rather than standard Azure Local procedures.
“I need to troubleshoot a VM issue on my rack-scale cluster.”: The agent will provide steps for using the serial console and monitoring tools specifically designed for Arc VMs within a multi-rack architecture.
“What are the prerequisites for setting up a new multi-rack instance?”: The agent will outline the necessary Network Fabric Controller and Cluster Manager setup, along with the required Azure CLI extensions and provider registrations.

Documentation by Microsoft

Azure Local Multi-Rack

Multi-rack is in preview — say so, and confirm availability from the docs before committing to a design.

Quick Reference

Property	Value
Best for	Rack-scale Azure Local: 100+ machines, preintegrated racks, SAN, managed fabric
Scale	Minimum four racks — one aggregation rack plus three or more compute racks
Providers	`Microsoft.NetworkCloud`, `Microsoft.ManagedNetworkFabric`, `Microsoft.AzureStackHCI`
CLI	`az networkcloud`, `az networkfabric`, `az stack-hci-vm`
Related skill	`azure-local` for standard 1-16 node and rack-aware deployments

When to Use This Skill

Use when the deployment is multi-rack / rack scale: preintegrated racks, an aggregation rack, a Network Fabric Controller, a Cluster Manager, SAN storage, or the networkcloud / managednetworkfabric CLI extensions.

Do not use for standard Azure Local (1-16 node hyperconverged, up to 64 disaggregated) or rack-aware clusters — hand off to the azure-local skill. If the scale is unclear, ask first: the two have separate, non-interchangeable procedures for the same-sounding tasks (logical networks, VM creation, NSGs).

MCP Tools

No dedicated MCP namespace. Use generic Azure MCP tools: mcp_azure_mcp_extension_cli_generate (confirm networkcloud/networkfabric extensions first), mcp_azure_mcp_monitor (needs Log Analytics), mcp_azure_mcp_resourcehealth (partial; not fabric or SAN health), mcp_azure_mcp_documentation (multi-rack articles only — standard Azure Local pages do not apply).

Details: cli-and-prereqs.

Workflow

Confirm this is multi-rack, not standard Azure Local — see When to Use.
Plan/deploy -> plan-and-deploy
VMs, AKS, images, disks -> workload-management
Fabric, isolation domains, load balancers, NSGs -> networking
Monitoring, metrics, serial console, failures -> operate-and-monitor

Read the matched workflow first and use docs-map. Start read-only. Ask before fabric changes, isolation domain edits, VM power/delete operations, or anything touching the aggregation rack or SAN.

Error Handling

Scenario	Remediation
Scale unknown	Ask whether the deployment is multi-rack or standard before recommending procedures.
Standard Azure Local detected	Hand off to the `azure-local` skill; multi-rack procedures do not apply.
Missing CLI extension	Install per cli-and-prereqs before running commands.
Risky fabric or SAN change	Stop and follow safety-rules.
Doc URL 404/redirect	Search Learn for the title, scoped to multi-rack deployments of Azure Local.

Multi-Rack Safety Rules

Multi-rack instances host large-scale production workloads across shared racks, a shared SAN, and a managed network fabric. A single change can affect hundreds of machines.

Always read-only first

Start every investigation with show/list commands and ARG queries. Establish the current state before proposing any change.

Confirm before acting

Ask for explicit user confirmation before anything in this table.

Action	Why it is risky
Network fabric changes	Fabric config is instance-wide; errors can isolate racks or break east-west traffic.
Isolation domain create/update/delete	Alters L2/L3 segmentation for running workloads.
Route policy changes	Can withdraw or import routes affecting north-south connectivity.
Bare metal machine power, restart, reimage, replace	Removes capacity and can move or destroy workloads.
Rack-level operations	Affects every machine in the rack.
Storage appliance / SAN operations	Shared by all compute racks; risk of data loss.
Cluster Manager or NFC changes	Control plane for the whole instance and, for NFC, potentially multiple instances.
VM power, delete, or disk operations	Direct workload impact.
Custom location or extension changes	Breaks the workload control path.

Preview caveat

Multi-rack is in preview. Do not assert that an operation is supported, reversible, or GA-backed without confirming in current documentation. Tell the user when guidance depends on preview behavior.

Scale-confirmation rule

Before giving any procedure, confirm the deployment is multi-rack. Applying standard Azure Local procedures to a multi-rack instance — or the reverse — produces commands that fail or, worse, act on the wrong control plane.

Evidence before diagnosis

Collect subscription, resource group, region, cluster name, Cluster Manager, NFC, rack identifiers, and affected machine or VM IDs before drawing conclusions. Never infer fabric or SAN health from Azure Resource Health alone.

Boundaries

Do not generate destructive commands as "examples"; the user may run them.
Do not work around a missing permission by proposing a broader role assignment without flagging it.
Do not recommend decommissioning, rack removal, or redeployment as a first troubleshooting step.
