# v9.0.1 Release Notes

# v9.0.1 LTS Release Notes

- Compatible Plugin API version: 1.4.1
- Compatible HPE Morpheus VM Essentials Worker version: 9.0.0+

Release Dates

- v9.0.1 July 2026

After upgrading to v9.0.1, it is recommended to check for HVM Host agent upgrades as well. To upgrade HVM Host agents, navigate to the detail page for each HVM Host, expand the ACTIONS menu, and click "Upgrade Agent." This process must be undertaken on all HVM Hosts. Alternatively, you may select "Download Agent Script" to download a shell script to handle the upgrade. Connect to the HVM Host over a terminal session and run the downloaded script. The scripts are unique to each HVM Host so you must download all required scripts and run the correct script against the correct HVM Host. Though many do, it is possible that some version upgrade hops will not contain an HVM Host agent upgrade.

# New features

API & CLI
:   - Added the ability to update a cluster layout version via the API and CLI, enabling automated upgrades of HVM clusters between versions.

HVM
:   - Updated virtual machine templates to include 2023 base boot loader certificates, ensuring support for future secure boot updates from Microsoft and other vendors.

Morpheus Core
:   - Introduced license tier-based gating (VM Essentials/Advanced/Enterprise) for AI-related features.
    - Enabled Morpheus Central websocket configuration by default in the installer to simplify registered tunnel connections.
    - New Administration > Settings > Morpheus Central tab provides an activation code for registering a Morpheus Appliance to Morpheus Central and displays registration status. See [Adding an appliance](https://support.hpe.com/hpesc/public/docDisplay?docId=sd00008095en_us&page=mc_add_appliances_glp.html) in Using HPE Morpheus Central for more information.

Networking
:   - Updated the HVM Network Plugin to preserve existing networks on a node when the node is deleted from the cluster.
    - Updated the ArubaCX Network Plugin to preserve existing OVS networks on switches when a node is deleted from the cluster.

# Fixes

HVM
:   - Fixed an issue where HVM cluster layout upgrades could fail during the finalize phase, sometimes causing nodes to incorrectly re-enter maintenance mode or the UI to report an incorrect layout version.
    - Resolved an issue where cluster creation could fail after adding nodes due to a mismatch in bundled UEFI firmware asset versions.
    - Fixed a race condition where cluster layout upgrades could fail if a host entered maintenance mode while its agent was still in a post-restart recovery cycle.
    - Resolved an issue where long-running cluster layout upgrades could fail if the database connection was closed by the connection pool during the finalize phase.
    - Fixed an issue where HVM layout upgrades would fail if host agents were not manually upgraded beforehand; the process now correctly handles automated agent upgrades.
    - Resolved an issue where a GFS2 datastore (now called HPE Clustered Datastore (Shared LUN) in the Morpheus UI) could incorrectly enter a read-only state following a kernel upgrade and node reboot.
    - Fixed an issue where SCSI reservation keys were not properly cleared from multipath configurations during a layout upgrade to HVM 1.3.
    - Resolved an issue where backup restoration or VM cloning would fail if the original source image had been deleted from the library.
    - Fixed formatting and labeling inconsistencies on the HVM cluster summary page.

CLI
:   - Added missing CLI commands and prompts to configure heartbeat targets and secure metadata parameters for clustered datastores.

Morpheus Core
:   - Fixed an issue where refreshing the browser on the Support Bundles tab would incorrectly redirect the user to the main Health tab.
    - Resolved a "permission denied" error during Morpheus agent upgrades on hosts where the /tmp directory is mounted with noexec permissions.
    - Fixed a regression where editing a storage server from the list view would result in blank URL and credential fields.
    - Fixed an installer issue where upgrades could fail with a "ports are listening" error if the initial appliance configuration had not completed successfully.
    - Fixed an issue where the UI failed to display an error message when a network configuration save operation failed.
    - Fixed a regression where overly restrictive validation prevented the use of special characters in instance names shown in the Morpheus UI.
    - Fixed an issue where RabbitMQ plugin enablement could fail during an appliance upgrade due to deprecated policies.

Plugin AlletraMP
:   - Fixed an issue where creating a storage volume under an existing volume set would incorrectly create a new volume set instead.

Kubernetes
:   - Resolved a dependency conflict that caused HKS Kubernetes cluster provisioning to fail on HVM clusters.
