Exiting the AX node from maintenance mode

After updating the AX node, exit the storage maintenance mode and node maintenance mode by running the following commands:

Get-StorageFaultDomain -type StorageScaleUnit | Where-Object {$_.FriendlyName -eq

"<Hostname>"} | Disable-StorageMaintenanceMode

Resume-ClusterNode -Name “Hostname” -Failback Immediate

These commands initiate the operation of rebuilding and rebalancing the data to ensure load balancing.

For the remaining cluster nodes, repeat the preceding procedures for conducting maintenance operations.

Expanding the Azure Stack HCI cluster

Expanding cluster compute or storage capacity are tasks performed during cluster operations. This section provides instructions for

performing these tasks.

Figure 20. Expanding the Azure Stack HCI cluster

Azure Stack HCI node expansion

In an HCI cluster, adding server nodes increases the storage capacity, improves the overall storage performance of the cluster, and

provides more compute resources to add virtual machines. Before adding new server nodes to an HCI cluster, complete the following

requirements:

• Verify that the processor model, HBA 330, and NICs are of the same configuration as the current nodes on the cluster and PCIe slots.

• Ensure that all disk types and the amount in each node are the same as the node in use. Do not combine two different disk types in the

same cluster or node. For example, you cannot combine SATA and SAS HDD/SSD drives in the same node or cluster. The following

table shows the supported options for expanding storage capacity of the cluster.
