Verify Hardware Acceleration Support Details
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
u
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

List Hardware Acceleration Claim Rules
Each block storage device managed by a VAAI plug-in needs two claim rules. One claim rule specifies the
hardware acceleration filter and another specifies the hardware acceleration plug-in for the device. You
can use the esxcli commands to list the hardware acceleration filter and plug-in claim rules.
