Configuring NMP Round Robin on a PowerStore Volume Already Presented
to the ESXi Host
Follow this procedure to configure NMP 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 already presented to the host. For volumes not yet presented to the
host, refer to Configuring vSphere NMP Round Robin as the default pathing policy for all volumes.
Steps
1. Open an SSH session to the host as root.
2. Run the following command to obtain the NAA of PowerStore LUNs presented to the ESXi host:
#esxcli storage nmp path list | grep DellEMC -B1
The following example demonstrates issuing the esxcli storage nmp path list command to obtain the NAA of all
PowerStore LUNs presented to the ESXi host:
#esxcli storage nmp path list | grep DellEMC -B1

3. Run the following command to modify the path selection policy on the PowerStore volume to Round Robin:
#esxcli storage nmp device set --device="<naa_id>" --psp=VMW_PSP_RR
For example:
#esxcli storage nmp device set --device="naa.68ccf098003f1461569ea4750e9dac50" --
psp=VMW_PSP_RR
4. Run the following command to set the NMP Round Robin path switching frequency on PowerStore volumes from the default
value (1000 I/O packets) to 1:
