  • Introduced a health fault alert that is raised when there are available updates on the system. [27253002]

Arc VM management changes

This release contains the following changes for Arc VM management:

  • 12 new Azure Marketplace images went live. For more information, see Create Azure Stack HCI VM from Azure Marketplace images via Azure CLI.
  • Creation of logical networks is blocked if trying to create with overlapping IP pools.
  • Logical network properties are properly updated. Previously, the logical network sometimes would not have its properties (vLAN, IP Pools, etc.) filled.
  • The vLAN field on a logical network will be defaulted to '0' if not specified.
  • Either (not both) -image or -os-disk-name can be used to create a VM from a VHD. Previously, Azure CLI enforced -image to be required for az stack-hci-vm create command.

For more information, see the Fixed issues list in 2408.

SBE changes

This release contains the following changes for SBE:

  • Reduced deployment times: Starting in this release, SBE extension interfaces are executed more efficiently leading to reduced Azure Stack HCI deployment times.
  • CAU plugin: Starting in this release, SBE extensions use an updated CAU plugin that enhances support for host OS driver updates, addressing issues with drivers newer than those in the SBE. This plugin update provides hardware vendors more flexibility for driver version updates in support cases. Microsoft recommends installing host OS driver updates only through your hardware vendor's SBE.
  • Improved error details: Starting in this release, hardware vendor SBE failures or exceptions will include the SBE publisher, family, and version at the beginning of the exception string. Provide this information to your hardware vendor to streamline the failure analysis.
