Setting Round-Robin Load Balancing Policy On ESX/ESXi-Based
Storage Arrays
NOTE: Perform this procedure after you have enabled ALUA on VMware ESX/ESXi and verified if the host server is
using ALUA for the MD storage array. For more information, see Enabling ALUA On VMware ESX/ESXi and
Verifying If Host Server Is Using ALUA For MD Storage Array.
To set a round-robin load balancing policy on your ESX/ESXi-based host server:
1. Do one of the following:
– For ESX 4.x, run the following command:
# esxcli nmp satp setdefaultpsp –psp VMW_PSP_RR –satp VMW_SATP_ALUA/
VMW_SATP_LSI
– For ESX/ESXi 5.x, run the following command:
# esxcli storage nmp satp set --default-psp VMW_PSP_RR --satp
VMW_SATP_ALUA/VMW_SATP_LSI
2. Reboot your ESX-based host server.
