Inter Chassis Link behavior between two HP StorageWorks DC Directors Inter chassis links (ICL) is a licensed feature used to interconnect two DC Directors; there are two ICL connector ports ICL0 and ICL1 on each core blade, each aggregating a set of 16 ports. Thus each core blade provides 32 ICL ports and there are 64 ICL ports available for the entire DC Director chassis. All the ICL connector ports must be connected to the same two DC Director chassis. ICL ports can be used only with an ICL license. After the addition or removal of a license, the license enforcement is performed on the ICL ports only when you issue the portDisable or portEnable commands on the switch for the ports. All ICL ports must be disabled, and then re-enabled for the license to take effect. An ICL license must be installed on both platforms forming the ICL connection. ICL connector ports do not have SFPs, and the connectors used on the ICLs are proprietary. There are two LEDs-a status LED and an attention LED for each ICL connector port. The following table describes the behavior of the LEDs. Table 68 Led behavior LED Color Description Action Status Black No connection with peer blade. NA Attention Green Black ICL connection with peer blade is NA good. ICL is fully operational. NA Blinking Yellow One or more links in the ICL connection is NOT operational. Reconnect the ICL cables or replace the ICL cables. The ICL ports appear as regular FC ports, with some restrictions. All port parameters associated with ICL ports are static and all portCfg commands are blocked from changing any of the ICL port parameters. The only management associated with ICL ports and cables is monitoring the status of the LEDs on the ICL ports and any maintenance if the ATTENTION LED is blinking yellow. When you connect two DC Director platforms, the following features are supported: • 8 Gbps speed • Trunking • Credit sharing • QoS 232 Configuring Directors
