Display NMP Storage Devices

Use the esxcli command to list all storage devices controlled by the VMware NMP and display SATP

and PSP information associated with each device.

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

To list all storage devices, run the following command:

esxcli --server=server_name storage nmp device list

Use the --device | -d=device_ID parameter to filter the output of this command to show a single

device.

Add Multipathing Claim Rules

Use the esxcli commands to add a multipathing PSA claim rule to the set of claim rules on the system.

For the new claim rule to be active, you first define the rule and then load it into your system.

Examples when you add a PSA claim rule include the following:

You load a new multipathing plug-in (MPP) and must define the paths that this module claims.

You add new paths and want an existing MPP to claim them.

Caution When creating claim rules, avoid a situation where different physical paths to the same LUN

are claimed by different MPPs. Unless one of the MPPs is the MASK_PATH MPP, this configuration might

cause performance problems.
