Firmware and driver updates using the manual method
These procedures describe how to prepare and update firmware and drivers on an Azure Stack HCI cluster manually.
Preparing for maintenance operations
About this task
Use the following PowerShell commands to ensure that all the requirements are met before proceeding with the maintenance
operation of an AX node in an Azure Stack HCI cluster. These steps ensure that all the requirements are met and that no faults
exist before placing an AX node into maintenance mode.
Steps
1. Verify that all the nodes in the cluster are available by running the Get-clusternode command.
2. Verify that all the cluster networks are available by running the Get-ClusterNetwork command.
3. Verify that the cluster status is healthy by running the following commands:
Get-ClusterS2D
Get-StoragePool
Get-StorageSubSystem -FriendlyName *Cluster* | Get-StorageHealthReport
4. Verify that all the physical and virtual drives are healthy by running the following commands:
Get-physicaldisk
Get-virtualdisks
5. Verify that no back-end repair jobs are running by running the Get-storagejob command.
Placing an AX node in maintenance mode
About this task
After ensuring that the prerequisites are met and before performing the platform updates, place the AX node in maintenance
mode (pause and drain). You can move roles or VMs and gracefully flush and commit data in the AX node.
Steps
1. Run the following command to put the node in maintenance mode (pause and drain). Verify that all the roles and virtual
drives are drained properly and operational in other nodes after they are moved:
Suspend-ClusterNode -name Hostname -Drain
2. Place the target node in maintenance mode:
Get-StorageFaultDomain -type StorageScaleUnit | Where-Object {$_.FriendlyName -eq
"<Hostname>"} | Enable-StorageMaintenanceMode
3. Run the Get-Physical Disk command, and ensure that the Operational Status value is in maintenance mode for the
drives that belong to that server.
