Claim rules determine which multipathing module owns the paths to a particular storage device. They also define the type of multipathing support that the host provides to the device.
The claim rules are listed in the host’s /etc/vmware/esx.conf file.
- Core Claim Rules
- These claim rules determine which multipathing module, the NMP, HPP, or a third-party MPP, claims the specific device.
You can use the esxcli commands to add or change the core and SATP claim rules. Typically, you add the claim rules to load a third-party MPP or to hide a LUN from your host. Changing claim rules might be necessary when default settings for a specific device are not sufficient.
For more information about commands available to manage PSA claim rules, see the Getting Started with ESXCLI.
For a list of storage arrays and corresponding SATPs and PSPs, see the Storage/SAN section of the vSphere Compatibility Guide.
