Inter-Chassis Links
An Inter chassis link (ICL) is a licensed feature used to interconnect two HP StorageWorks DC SAN
Backbone Directors, two HP StorageWorks DC04 SAN Director Switches, or an HP StorageWorks DC
SAN Backbone Director and a HP StorageWorks DC04 SAN Director Switch. ICL ports in the core blades
are used to interconnect two HP StorageWorks Backbones, potentially increasing the number of usable
ports in the HP StorageWorks DC SAN Backbone Director or HP StorageWorks DC04 SAN Director
Switch chassis. The ICL ports on CORE8 and CR4S-8 are internally managed as E_Ports. These ports use
proprietary connectors instead of traditional SFPs. When two HP StorageWorks Backbones are
interconnected by ICLs, each chassis still requires a unique domain and is managed as a separate switch.
On the HP StorageWorks DC SAN Backbone Director there are two ICL connectors at 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 HP StorageWorks DC SAN Backbone Director chassis. All
the ICL connector ports must be connected to the same two HP StorageWorks DC SAN Backbone Directors
or HP StorageWorks DC04 SAN Director Switch chassis.
The HP StorageWorks DC04 SAN Director Switch has 2 ICL connector ports at ICL0 and ICL1, each
aggregating a set of 8 ports. Thus, each core blade provides 16 ICL ports and there are 32 ICL ports
available for the entire HP StorageWorks DC04 SAN Director Switch chassis. All the ICL connector ports
must be connected to the same two HP StorageWorks DC SAN Backbone Director or HP StorageWorks
DC04 SAN Director Switch chassis.
Only cross--ICL group connections are allowed:
ICL0 <--> ICL1
ICL1 <--> ICL0
The following ICL connections are not allowed:
ICL0 <--> ICL0
See Table 70
on page 275 for a list of blades and their corresponding IDs.
Status (Displays the status of the blade)
DIAG RUNNING POST1: The blade is present, powered on, and running
the post-initialization power-on self test (POST).
DIAG RUNNING POST2: The blade is present, powered on, and running
the POST.
ENABLED: The blade is on and enabled.
ENABLED (User Ports Disabled): The blade is on, but external ports have
been disabled with the bladeDisable command.
DISABLED: The blade is powered on but disabled.
FAULTY: The blade is faulty because an error was detected. The reason code
numbers displayed are used by Support personnel to assist with problem
diagnosis. Review the system error logs for more information.
INITIALIZING: The blade is present, powered on, and initializing hardware
components.
INSERTED, NOT POWERED ON: The blade is present in the slot but is
turned off.
LOADING: The blade is present, powered on, and loading initial
configuration.
POWERING UP: The blade is present and powering on.
UNKNOWN: The blade is inserted but its state cannot be determined.
VACANT: The slot is empty.
