This article explains how to add or repair servers (nodes) for your Azure Local rack aware cluster.
Important
This feature is currently in PREVIEW. See the Supplemental Terms of Use for Microsoft Azure Previews for legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.
Add a server
For more information on adding a server, see Add a node on Azure Local.
Limitations
This is only supported for 2+2 to 3+3, and 3+3 to 4+4 rack aware cluster. You can't add nodes to a 1+1 rack aware cluster. For a rack aware cluster, you must add two nodes at a time by using the Add-Server command:
Add-Server -Name <String Array> -HostIpv4 <String Array> -LocalAvailabilityZone <String Array> -LocalAdminCredential <Credential>
Parameters
The following parameters can be used with the Add-Server command:
Name: String array with names of two nodes.
HostIpv4: String array with two IPv4 addresses for the two nodes. Ensure that the IPv4 addresses are listed in the same respective order as the two nodes for the Name parameter.
LocalAvailabilityZone: String array of local availability zones in the respective order of the nodes being added. You need to ensure the nodes are added to the correct zone.
For example, if you are adding nodes ["Node1", "Node2"] and Node1 is in ZoneA, and Node2 is in ZoneB, then the value should be ["ZoneA", "ZoneB"].
LocalAdminCredential: Local administrator user credentials for the nodes. Use the same credential for both nodes.
To validate that the nodes were added successfully, run the Get-ClusterFaultDomain command. You should see the two nodes are listed and added to the correct zone.
[<IP address>]: PS C:\> Get-ClusterFaultDomain
Name Type ParentName ChildrenNames Location
---- ---- ---------- ------------- --------
Site <IP address>/24 Site {Zone1, Zone2}
Zone1 Rack Site <IP address>/24 {ASRRR15, ASRRR16, ASRRR17, ASRRR18}
Zone2 Rack Site <IP address>/24 {ASRRR25, ASRRR26, ASRRR27, ASRRR28}
ASRRR15 Node Zone1
ASRRR16 Node Zone1
ASRRR17 Node Zone1
ASRRR18 Node Zone1
ASRRR25 Node Zone2
ASRRR26 Node Zone2
ASRRR27 Node Zone2
ASRRR28 Node Zone2
You can also see the zone and node information in the Azure portal by going to your Azure Local resource page and under Infrastructure selecting Machines:
Repair a server
You can repair nodes in your Azure Local rack aware cluster. You may need to repair a node in your system if there is a hardware failure. For more information, see Repair a node on Azure Local.
