Issue/Introduction

  • The host is marked as "Not Responding" in vCenter Server, the Virtual Machines keep running on the host.
  • The DCUI console displays the error: Bootbank cannot be found at path '/bootbank'

  • IPMI logs on the iLO may report: The iLO health monitoring status of the device/adapter located in Slot ## is not responsive.

  • The device in Slot ## is identified as the NVMe boot device.
  • Attempts to access logs on the ESXi host makes the SSH session may hung.
  • Under /var/run/log/syslog.log, below error log snips are found:

    YYYY-MM-DDTHH:MM:SS Wa(##) smartd[#######]: t10.NVMe____########___________________________############: REALLOCATED SECTOR CT below threshold (0 < 90)

  • Under /var/run/log/vmkernel.log, below error log snips are found:

Cause

  • The device in Slot ## mentioned in the issue corresponds to the NVMe boot device.
  • This issue is caused by a firmware bug affecting the HPE NVMe boot device, specific to HPE Gen 10 or higher servers with the Boot Controller NS204i.
  • The ESXi kernel loses connection to the boot partition, the bootbank becomes inaccessible, causing management services to hang.
