2.
Run the following command to configure the default pathing policy for newly defined PowerStore volumes to Round Robin
with path switching after each I/O packet:
$ esxcli storage core claimrule add -u -t vendor --nvme-controller-model "dellemc-
powerstore" -P HPP -g "pss=LB-IOPS,iops=1"
3.
Reboot the host.
4.
Verify that all volumes deriving from NVMe-oF are properly claimed.
$ esxcli storage hpp devide list | grep "Device Display Name: NVMe\|Path Selection"
Device Display Name: NVMe TCP Disk (eui.b635f9c20e1cb3658ccf096800ce9565)

Configuring HPP Round Robin on a PowerStore Volume Already Presented
to the ESXi Host
Follow this method to configure HPP Round Robin on a PowerStore volume that is already presented to the ESXi host, using
ESXi command line.
About this task
NOTE:
Use this method only for PowerStore volumes that are already presented to the host. For volumes that are not yet
presented to the host, see
Configuring HPP Round Robin as the Default Pathing Policy for all PowerStore Volumes
.
Steps
1.
Open an SSH session to the host as
root
.
2.
Run the following command to retrieve the list of namespaces (in the example, there are three namespaces: NSID 50, 51,
and 52):
$ esxcli nvme namespace list
Name
Controller Number
Namespace ID
Block Size
Capacity in MB
