Limitations in DataCore Puls8 v4.4

This section outlines the supported boundaries, constraints, and operational conditions that restrict or influence the behavior of certain features in this release.

The items below specify the current limitations:

High Availability Not Supported on RHEL 10

High Availability (HA) functionality is not supported on RHEL 10 and its derivative distributions. This limitation is due to the removal of the nvme_core.multipath kernel parameter in RHEL 10, which is required for enabling volume failover in HA configurations. If you deploy DataCore Puls8 on RHEL 10-based environments, HA will not function as expected. Volume failover may fail, potentially leading to reduced availability and resilience.

Recommended Action: To use the HA feature, ensure you are running on a Linux distribution that supports the nvme_core.multipath kernel parameter.
