Chapter 24 Storage Hardware AccelerationVerify Hardware Acceleration Support DetailsUse the esxcli command to query the block storage device about the hardware acceleration support thedevice provides.In the procedure, --server=server_name specifies the target server. The specified target server prompts youfor a user name and password. Other connection options, such as a configuration file or session file, aresupported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces.PrerequisitesInstall vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started withvSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.ProcedureuRun the esxcli --server=server_name storage core device vaai status get -d=device_IDcommand.If the device is managed by a VAAI plug-in, the output shows the name of the plug-in attached to thedevice. The output also shows the support status for each T10 SCSI based primitive, if available. Outputappears in the following example:# esxcli --server=server_name storage core device vaai status get -d naa.XXXXXXXXXXXX4cnaa.XXXXXXXXXXXX4cVAAI Plugin Name: VMW_VAAIP_SYMMATS Status: supportedClone Status: supportedZero Status: supportedDelete Status: unsupportedList Hardware Acceleration Claim RulesEach block storage device managed by a VAAI plug-in needs two claim rules, one that specifies thehardware acceleration filter and another that specifies the hardware acceleration plug-in for the device. Youcan use the esxcli commands to list the hardware acceleration filter and plug-in claim rules.Procedure1 To list the filter claim rules, run theesxcli --server=server_name storage core claimrule list --claimrule-class=Filter command.In this example, the filter claim rules specify devices that should be claimed by the VAAI_FILTER filter.# esxcli --server=server_name storage core claimrule list --claimrule-class=FilterRule Class Rule Class Type Plugin MatchesFilter65430 runtime vendor VAAI_FILTER vendor=EMC model=SYMMETRIXFilter 65430 file vendor VAAI_FILTER vendor=EMC model=SYMMETRIXFilter65431 runtime vendor VAAI_FILTER vendor=DGC model=*Filter 65431 file vendor VAAI_FILTER vendor=DGC model=*VMware, Inc. 239
