Applicable Products

Limitations
While high availability (HA) enhances system reliability and service continuity, certain features are currently not supported in HA environments due to architectural limitations or potential conflicts during failover operations.
To ensure system stability and predictable behaviors, these unsupported features will either be automatically disabled when HA is enabled or must be manually removed before creating a cluster.
Below is a list of known features and services that are not supported by the current version of High Availability Manager. Please review this list carefully before configuring your HA cluster.
Note
- The following table lists only the features that are unsupported when the system is in an HA environment.
- For the list of features generally unsupported in QuTS hero h5.3.0 (regardless of whether HA is enabled), please refer to What applications and utilities are supported in QuTS hero h5.3.0?
