We have hosts that were recently setup. I installed the latest version of NCM via VMWare Update Manager prior to configuring/scanning for iscsi volumes. I am noticing now that the path policy is set to Round Robin and not Nimble_PSP_Directed. I am not sure if the old nimble psp (for IO change and Round Robin) script was run against these machines or what. I do notice when I create a new volume it sets to nimble_psp_directed as it should.
That said is there a script that will change the psp to nimble_psp_directed? I only have one for the old round robin psp.
