Cause

The disk storageAccountType and zone configuration are not compatible.

Azure enforces the following rules:

• Locally redundant storage [standard_LRS or premium_LRS]

  • A zone must be defined

  • The zone value cannot be null
    
    

• Zone‑redundant storage for managed disks [standard_ZRS or premium_ZRS]

  • The zone can be null
    
    

• Regional disks

  • To use a regional disk with zone = null, the disk must use ZRS
    
    

If these requirements are not met, Azure prevents the stateful node from importing or launching.

Solution

1. Check the disk storage account type

   Review the stateful node configuration and identify the storageAccountType used for the OS disk or data disks.
   
   

2. Verify the zone setting

   Confirm that the zone setting matches the disk type:

   • For LRS disks, set a valid availability zone.

   • For ZRS disks, you can leave the zone unset.
     
     

3. Update the configuration

   Modify the disk type or zone setting so they are compatible, based on the rules above.
   
   

4. Retry the import or launch

   After correcting the configuration, import or launch the stateful node again.
