on a fly Can we Change PSP in ESXi5.1 without impacting running VMs

Dear Team,

I have one SAN LUN datastore and default PSP is Round Robin, Just want to confirm if I change PSP from RR to Fixed, will there be any impact on running VMs which are hosted on same datastore.

regards

Mr VMware

Hi MrVmware,

As others said there is no impact at all. However, if you add more LUNs in future they all will be added as RR unless you change the default PSP to fixed at the host level.

Thanks,
