List Hardware Acceleration Claim Rules
Each block storage device managed by a VAAI plug-in needs two claim rules, one that specifies the hardware
acceleration filter and another that 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.
Procedure
1 To list the filter claim rules, run the
esxcli --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=Filter
Rule Class Rule Class Type Plugin Matches
Filter 65430 runtime vendor VAAI_FILTER vendor=EMC model=SYMMETRIX
Filter 65430 file vendor VAAI_FILTER vendor=EMC model=SYMMETRIX
Filter 65431 runtime vendor VAAI_FILTER vendor=DGC model=*
Filter 65431 file vendor VAAI_FILTER vendor=DGC model=*
2 To list the VAAI plug-in claim rules, run the
esxcli --server=server_name storage core claimrule list --claimrule-class=VAAI command.
In this example, the VAAI claim rules specify devices that should be claimed by a particular VAAI plugin.
esxcli --server=server_name storage core claimrule list --claimrule-class=VAAI
Rule Class Rule Class Type Plugin Matches
VAAI 65430 runtime vendor VMW_VAAIP_SYMM vendor=EMC model=SYMMETRIX
VAAI 65430 file vendor VMW_VAAIP_SYMM vendor=EMC model=SYMMETRIX
VAAI 65431 runtime vendor VMW_VAAIP_CX vendor=DGC model=*
VAAI 65431 file vendor VMW_VAAIP_CX vendor=DGC model=*
Add Hardware Acceleration Claim Rules
To configure hardware acceleration for a new array, you need to add two claim rules, one for the VAAI filter
and another for the VAAI plug-in. For the new claim rules to be active, you first define the rules and then load
them into your system.
This procedure is for those block storage devices that do not support T10 SCSI commands and instead use the
VAAI plug-ins.
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.
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
1 Define a new claim rule for the VAAI filter by running the
esxcli --server=server_name storage core claimrule add --claimrule-class=Filter -plugin=VAAI_FILTER
command.
2 Define a new claim rule for the VAAI plug-in by running the
esxcli --server=server_name storage core claimrule add --claimrule-class=VAAI command.
