+Set the new IOPS value using the following command:
+  esxcli storage nmp psp roundrobin deviceconfig set -d t10.FreeBSD_iSCSI_Disk______001517bc5bf6001_________________ -t iops -I 1
+In this case it is value 1. I have bench-marked 4 values (1000 (default), 100, 10 and 1)
+=====SATP rule====
+To make it last a reboot:
+  esxcli storage nmp satp rule add -s "VMW_SATP_ALUA" -P "VMW_PSP_RR" -O iops=1 -c "tpgs_on" -M "iSCSI Disk" -e "FreeNAS iSCSI custom SATP Claimrule"
