For the paths managed by the NMP module, a second set of claim rules is applied. These rules determine
which Storage Array Type Plug-In (SATP) should be used to manage the paths for a specific array type, and
which Path Selection Plug-In (PSP) is to be used for each storage device.
Use the vSphere Client to view which SATP and PSP the host is using for a specific storage device and the
status of all available paths for this storage device. If needed, you can change the default VMware PSP using
the client. To change the default SATP, you need to modify claim rules using the vSphere CLI.
You can find some information about modifying claim rules in the vSphere Storage documentation.
For more information about the commands available to manage PSA, see Getting Started with vSphere
Command-Line Interfaces.
For a complete list of storage arrays and corresponding SATPs and PSPs, see the SAN Array Model
Reference section of the vSphere Compatibility Guide.
View Datastore Paths in the vSphere Client
Use the vSphere Client to review the paths that connect to storage devices the datastores are deployed on.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Procedure
1 Log in to the vSphere Client and select a host from the inventory panel.
2 Click the Configuration tab and click Storage in the Hardware panel.
3 Click Datastores under View.
4 From the list of configured datastores, select the datastore whose paths you want to view, and click
Properties.
5 Under Extents, select the storage device whose paths you want to view and click Manage Paths.
6 In the Paths panel, select the path to view.
The panel underneath displays the path's name. The name includes parameters describing the path:
adapter ID, target ID, and device ID.
7 (Optional) To extract the path's parameters, right-click the path and select Copy path to clipboard.
View Storage Device Paths in the vSphere Client
