Use the esxcli command to query whether the block storage device provides the hardware acceleration support.
Before you begin
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.
About this task
In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.
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 --server=server_name 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
