Installation and Configuration 5-29 Table 5-2 Active Array Controller Locations Configuration Active/Standby Active/Active: Cabling Method 1 Active/Active: Cabling Method 2 Active Array Controller Location Top array controller slot Top array controller slot Top array controller slot in odd-numbered RA4000/RA4100 Arrays Bottom array controller slot in even-numbered RA4000/RA4100 Arrays NOTE: If Secure Path Manager indicates that the active array controllers are already located in the proper slots, you do not need to redefine their locations by performing the following procedure. Changing the location of the active array controller changes the entire redundant Fibre Channel Fabric path or redundant FC-AL path, which includes the Fibre Host Adapter, the Storage Hub, FC-AL Switch, or Fibre Channel SAN Switch, and the RA4000 Array Controller. So, when you change the active array controller, you change the entire active Fibre Channel Fabric or FC-AL path. To change the active Fibre Channel Fabric or FC-AL path: IMPORTANT: Run Secure Path Manager from only one cluster node at a time. Otherwise, multiple Secure Path Manager processes will try to control the same RA4000/RA4100 Arrays.
