Chapter 4 Configuration • Hard Loop IDs - Sets the Hard Loop ID for each controller and port combination. Enable a controller/port combination by checking its check box. Values allow use of the same Loop IDs all the time. Set these options by selecting a value from the option's drop-down list. • PCI Latency Control - Controls the amount of data each front end Fibre Protocol Processor can burst across the primary PCI bus before relinquishing bus ownership. Settings are Short, Medium, Long. A setting of Long is recommended. • Frame Control - Allows adjustment of the FC chip's frame size. • Topology - A value of 0 requires use of two ports on each controller, one active and one inactive. The active port is for normal traffic; the inactive port is for the partner's traffic after failover. A value of 4 configures the controller pair for master/slave operation. If one controller fails, the other joins the loop on both ports and assumes I/O for the failed controller. (Values 1, 2, and 3 are currently undefined.) Recording Your Changes To save your selections do one of the following: • Click OK in the Advanced Controller Options, Expert Controller Options, and/or Fibre Controller Options dialog boxes to accept the changes. • Or, click the Cancel button to delete the changes. Intelligent BBU Setup The Intelligent Battery Backup Unit (BBU) dialog box is used to monitor and charge or recharge the backup battery pack on the FCArray Controller card. This battery pack maintains the FCArray Controller's user data in RAM in case the Rack Storage/12FC disk storage system loses AC power. The Intelligent BBU dialog box provides several options, such as an alarm to indicate when the existing battery pack needs to be recharged or when a new battery pack is needed. This dialog box also provides reconditioning of the battery pack (a discharge and charge cycle). See Figure 4-26. 57
