n
Any paths not described in the previous rules are claimed by NMP.
n
The Rule Class column in the output describes the category of a claim rule. It can be MP (multipathing
plug-in), Filter, or VAAI.
n
The Class column shows which rules are dened and which are loaded. The file parameter in the Class
column indicates that the rule is dened. The runtime parameter indicates that the rule has been loaded
into your system. For a user-dened claim rule to be active, two lines with the same rule number should
exist, one line for the rule with the file parameter and another line with runtime. Several low
numbered rules, have only one line with the Class of runtime. These are system-dened claim rules that
you cannot modify.
Display Multipathing Modules
Use the esxcli command to list all multipathing modules loaded into the system. Multipathing modules
manage physical paths that connect your host with storage.
In the procedure, --server=server_name species the target server. The specied target server prompts you
for a user name and password. Other connection options, such as a conguration le or session le, are
supported. For a list of connection options, see Geing Started with vSphere Command-Line Interfaces.
Prerequisites
Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Geing Started with
vSphere Command-Line Interfaces. For troubleshooting, run esxcli commands in the ESXi Shell.
Procedure
u
To list multipathing modules, run the following command:
esxcli --server=server_name storage core plugin list --plugin-class=MP
This command typically shows the NMP and, if loaded, the MASK_PATH module. If any third-party MPPs
have been loaded, they are listed as well.
Display SATPs for the Host
Use the esxcli command to list VMware NMP SATPs loaded into the system. Display information about the
SATPs.
In the procedure, --server=server_name species the target server. The specied target server prompts you
for a user name and password. Other connection options, such as a conguration le or session le, are
supported. For a list of connection options, see Geing Started with vSphere Command-Line Interfaces.

Procedure
u
To list VMware SATPs, run the following command:
esxcli --server=server_name storage nmp satp list
For each SATP, the output displays information that shows the type of storage array or system this SATP
supports and the default PSP for any LUNs using this SATP. Placeholder (plugin not loaded) in the
Description column indicates that the SATP is not loaded.
