Use the esxcli command to query whether the block storage device provides the hardware acceleration support.

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 vaai status get -d=device_ID command.

If a VAAI plug-in manages the device, the output shows the name of the plug-in attached to the device. The output also shows the support status for each T10 SCSI based primitive, if available. Output appears in the following example:

# esxcli storage core device vaai status get -d naa.XXXXXXXXXXXX4c
naa.XXXXXXXXXXXX4c
 VAAI Plugin Name: VMW_VAAIP_SYMM
 ATS Status: supported
 Clone Status: supported
 Zero Status: supported
 Delete Status: unsupported
