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.

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=*

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 plug-in.

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=*
