Symptoms

Symptoms:
  • Hosts connected using NVMe/FC or NVMe/TCP may experience I/O errors during node reboots or NDU.

Environment:
  • ESXi Host 8.0 U1 is connected to PowerStore volumes/vVols. 
  • Host is connected using NVMe/FC or NVMe/TCP.

Cause

This is a VMware regression issue introduced in ESXI version 8. 0 U1. In this release, ESXi introduced a Native NVMe stack (aka E2E NVMe stack). Certain error codes that had a retry in previous versions of ESXI no longer have a retry applied. As a result the end applications may experience I/O failures.

Resolution

Upgrade ESXI to version 8.0 U1c or later.
