Hello,  We upgraded PS6100 firmware to 8.0.3 before "NAS Cluster Add".  As a result, "NAS Cluster add" failed. 　psgroup> nas-cluster select fscluster00 controller add 　% Error - NAS controller firmware version is not compatible with the PS Series group firmware version. Operation is not allowed. Isn't there a good method for that?  ---Current Firmware Version--- PS6100 firmware : 8.0.3  FS7600 firmware : 3.0.940120 ------  Please me advice.  Kensuke Maeda
