Changing the Default Path Selection Policy (PSP) for an SATP vSphere 5.1

I have VNX5300 Storage Without PowerPath.

IN VMware HCL  Storage/SAN  Compatibility we can see:
PSP Plugin mast be “VMW_PSP_FIXED”
SATP Plugin mast be “VMW_SATP_ALUA_CX”

HCL VNX5300
when i add A LUN to ESXi be Default PSP is : “VMW_PSP_RR”

we can change it by Enter the SSH and run several commands:

First of all, lets see all the Default PSP really is.

The command below shows us that the default PSP for VMW_SATP_ALUA is indeed VMW_PSP_RR.

satp-list-1

# esxcli storage nmp satp list

we are going to change it to VMW_SATP_FIXED according VMware HCL

satp-set-01

# esxcli storage nmp satp set -s VMW_SATP_ALUA -P VMW_PSP_FIXED

Default PSP for VMW_SATP_ALUA is now VMW_PSP_FIXED

Lets confirm that the the default PSP has changed.

satp-list-2

# esxcli storage nmp satp list
