The server is connected to Hitachi VSP 5600H storage NVMe-oF ports through two paths via Emulex LPe36002 adapter. NVM Subsystem is configured in the storage and assigned a few namespaces to the host.

NVMe-oF namespaces (LUNs) are not detected in the host after the system reboot. With the manual command "nvme connect", namespaces can be detected. No errors are recorded in the server logs related to this incident.
