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.

Procedure

  1. To list the filter claim rules, run the esxcli storage core claimrule list --claimrule-class=Filter command.

    In this example, the filter claim rules specify devices that the VAAI_FILTER filter claims.

    # esxcli storage core claimrule list --claimrule-class=Filter

  2. To list the VAAI plug-in claim rules, run the esxcli storage core claimrule list --claimrule-class=VAAI command.

    In this example, the VAAI claim rules specify devices that the VAAI plug-in claims.

    esxcli storage core claimrule list --claimrule-class=VAAI
