List Hardware Acceleration Claim Rules<br />
Each block storage device managed by a VAAI plug-in needs two claim rules, one that specifies the hardware<br />
acceleration filter and another that specifies the hardware acceleration plug-in for the device. You can use the<br />
esxcli commands to list the hardware acceleration filter and plug-in claim rules.<br />
Procedure<br />
1 To list the filter claim rules, run the<br />
esxcli --server=server_name storage core claimrule list --claimrule-class=Filter command.<br />
In this example, the filter claim rules specify devices that should be claimed by the VAAI_FILTER filter.<br />
# esxcli --server=server_name storage core claimrule list --claimrule-class=Filter<br />
Rule Class Rule Class Type Plugin Matches<br />
Filter 65430 runtime vendor VAAI_FILTER vendor=EMC model=SYMMETRIX<br />
Filter 65430 file vendor VAAI_FILTER vendor=EMC model=SYMMETRIX<br />
Filter 65431 runtime vendor VAAI_FILTER vendor=DGC model=*<br />
Filter 65431 file vendor VAAI_FILTER vendor=DGC model=*<br />
2 To list the VAAI plug-in claim rules, run the<br />
esxcli --server=server_name storage core claimrule list --claimrule-class=VAAI command.<br />
In this example, the VAAI claim rules specify devices that should be claimed by a particular VAAI plugin.<br />
esxcli --server=server_name storage core claimrule list --claimrule-class=VAAI<br />
Rule Class Rule Class Type Plugin Matches<br />
VAAI 65430 runtime vendor VMW_VAAIP_SYMM vendor=EMC model=SYMMETRIX<br />
VAAI 65430 file vendor VMW_VAAIP_SYMM vendor=EMC model=SYMMETRIX<br />
VAAI 65431 runtime vendor VMW_VAAIP_CX vendor=DGC model=*<br />
VAAI 65431 file vendor VMW_VAAIP_CX vendor=DGC model=*<br />
Add Hardware Acceleration Claim Rules<br />
To configure hardware acceleration for a new array, you need to add two claim rules, one for the VAAI filter<br />
and another for the VAAI plug-in. For the new claim rules to be active, you first define the rules and then load<br />
them into your system.<br />
This procedure is for those block storage devices that do not support T10 SCSI commands and instead use the<br />
VAAI plug-ins.<br />
In the procedure, --server=server_name specifies the target server. The specified target server prompts you<br />
for a user name and password. Other connection options, such as a configuration file or session file, are<br />
supported. For a list of connection options, see Getting Started with <strong>vSphere</strong> Command-Line Interfaces.<br />
Prerequisites<br />
Install vCLI or deploy the <strong>vSphere</strong> Management Assistant (vMA) virtual machine. See Getting Started with<br />
<strong>vSphere</strong> Command-Line Interfaces. For troubleshooting , run esxcli commands in the <strong>ESXi</strong> Shell.<br />
Procedure<br />
1 Define a new claim rule for the VAAI filter by running the<br />
esxcli --server=server_name storage core claimrule add --claimrule-class=Filter -plugin=VAAI_FILTER<br />
command.<br />
2 Define a new claim rule for the VAAI plug-in by running the<br />
esxcli --server=server_name storage core claimrule add --claimrule-class=VAAI command.<br />
