Use the esxcli command to verify the hardware acceleration support status of a particular storage device.

Prerequisites

Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.

Procedure

  • Run the esxcli storage core device list -d=device_ID command.
    The output shows the hardware acceleration, or VAAI, status that can be unknown, supported, or unsupported.
