Direct-attached NVMe Solid State Drives (SSDs) may unexpectedly disappear from the Operating System (OS) according to the HPE Integrated Management Log (IML). The drives will be reported to be "removed," and then reappear as "inserted" a short time later. This is due to a communication issue between the iLO and the drive backplane, resulting in the drive backplane executing a long reset. This long reset also involves a full reset on the attached NVMe drives that appears to the host as a drive removal and subsequent insertion.For example, when this issue happens, messages may record drives as removed and reinserted in the HPE Integrated Management Log (IML):"NVMe Storage - Drive at Embedded:Port=XX:Box=Y:Bay=Z status changed toRemovedACTION: 1. Verify cables are good and fully seated. 2. Ensure all drives are fully seated. 3. Verify backplane, controller, and drive compatibility. 4. Replace the defective drive.""NVMe Storage - Drive at Embedded:Port=XX:Box=Y:Bay=Z status changed toInsertedACTION: 1. Verify cables are good and fully seated. 2. Ensure all drives are fully seated. 3. Verify backplane, controller, and drive compatibility. 4. Replace the defective drive."
Any HPE server running any HPE Integrated Lights-Out 5 (iLO 5) or iLO 6 firmware version with direct-attached NVMe Solid State Drives (SDDs) for HPE SR416i/SR932 controllers, HPE Smart Array controllers, or HPE MR216/416/408 controllers managed by the HPE Universal Backplane Management 6 (UBM6).Note: This issue rarely occurs in earlier UBM versions, e.g., UBM5/UBM4/UBM3.In addition, the following drive backplane parts are affected:DescriptionSpare Part Numbers2 SFF 24G x4 U.3 NVMe / SAS / SATA UBM6 BC (stacked)P62069-0018 SFF 24G x1 U.3 NVMe / SAS / SATA UBM6 BCP62070-0012 SFF 24G x4 U.3 NVMe / SAS / SATA UBM6 BC (side-by-side)P62071-0014 LFF 12G x1 SAS / SATA UBM6 LPP62075-0018 SFF 24G x4 U.3 NVMe / SAS UBM6 BCP62066-0012U 8SFF 16Gx4P62073-0011U 8SFF 16Gx4P62074-001
Update the Universal Backplane Management 6 (UBM6) toUBM6 Backplane PIC PLDM Firmware for Gen10/Gen10P/Gen11/Gen12 servers firmware version 1.06or later. The PLDM FWPKG components can be supported when drives are directly attached to the server.Typically, an operating system reboot is not required after an update to UBM6 firmware version 1.06.When the issue occurs, drive replacements will not be necessary, nor will it resolve the issue. In addition, any drive failure messages in IML can be safely ignored.
