Device Management with esxcli storage nmp device

The device option performs operations on devices currently claimed by the VMware NMP.

esxcli storage nmp device list

The
list
 command lists the devices controlled by VMware NMP and shows the SATP and PSP information associated with each device. To show the paths claimed by NMP, run
esxcli storage nmp path list
 to list information for all devices, or for just one device with the
--device
 option.
Options
Description
--device <device>
-d <device>
Filters the output of the command to show information about a single device. Default is all devices.

esxcli storage nmp device set

The
set
 command sets the PSP for a device to one of the policies loaded on the system.
Any device can use the PSP assigned to the SATP handling that device, or you can run
esxcli storage nmp device set --device naa.xxx --psp <psp>
 to specifically override the PSP assigned to the device.
  • If a device does not have a specific PSP set, it always uses the PSP assigned to the SATP. If the default PSP for the SATP changes, the PSP assigned to the device changes only after reboot or after a device is reclaimed. A device is reclaimed when you unclaim all paths for the device and reclaim the paths.
  • If you use
    esxcli storage nmp device set
     to override the SATPs default PSP with a specific PSP, the PSP changes immediately and remains the user-defined PSP across reboots. A change in the SATP's PSP has no effect.
Use the
--default
 option to return the device to using the SATP's PSP.
Options
Description
--default
-E
Sets the PSP back to the default for the SATP assigned to this device.
--device <device>
-d <device>
Device to set the PSP for.
--psp <PSP>
-P <PSP>
PSP to assign to the specified device. Call
esxcli storage nmp psp list
 to display all currently available PSPs. See Managing Path Policies.
See
vSphere Storage
 for a discussion of path policies.
To set the path policy for the specified device to
VMW_PSP_FIXED
, run the following command. 
esxcli <conn_options> storage nmp device set --device naa.xxx --psp VMW_PSP_FIXED
