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:

#esxcli storage nmp psp roundrobin deviceconfig set --device="<naa_id>" --iops=1 --type=iops

For example:

#esxcli storage nmp psp roundrobin deviceconfig set --

device="naa.68ccf098003f1461569ea4750e9dac50" --iops=1 --type=iops

5.

Run the following command to validate that changes were applied to all PowerStore LUNs:

#esxcli storage nmp device list | grep -B1 -A4 DellEMC

Each listed PowerStore LUN should have the following NMP settings:

•

Path Selection Policy: VMW_PSP_RR

•

Path Selection Policy Device Config: policy=rr, iops=1

The following example demonstrates issuing the

esxcli storage nmp device list

command to validate that changes were

applied to all PowerStore LUNs:

#esxcli storage nmp device list

|grep -B1 -A4
