3Par and ESXi configuration

As part of optimization, guides call for setting RoundRobin and iops=1. This allows for better balancing/distribution of data flow. After installing ESXi6, open up putty, connect, and run:

esxcli storage nmp satp rule add -s “VMW_SATP_ALUA” -P “VMW_PSP_RR” -O iops=1 -c “tpgs_on” -V “3PARdata” -M “VV” -e “HP 3PAR Custom iSCSI/FC/FCoE ALUA Rule”

You’ll need to reboot afterward so the quick way to reboot: # reboot
If you don’t have access to ssh or the system in in lockdown mode or if you want to issue the reboot programatically, try the ‘safe’ way: # vicfg-hostops –operation reboot -force
