Port Level Errors - HP StorageWorks 2/16 - SAN Switch User Manual

Using Quick Loop
If one of the above errors is detected on a switch, the partner reinitializes to form a
separate QuickLoop containing only the devices on the partner switch, creating
two QuickLoops. If the error condition is removed, the QuickLoops are
reinitialized to form a single QuickLoop. If the recovery procedure fails, the
switches remain in the single switch QuickLoops, and the procedure is executed
again after a time-out period.

Port Level Errors

The following conditions are considered faulty in regards to the related looplet:
If an error is detected on a looplet, the QuickLoop is reinitialized with the looplet
excluded. The error condition is monitored, and if the condition is removed, the
looplet is re-included into the QuickLoop.
The looplet error recovery procedure includes the following steps:
1. LIPs are issued to the looplet, and it is determined whether the hidden
2. The rest of the standard Loop Initialization Sequences are completed, and it is
3. The looplet is kept idle and it is determined whether it remains stable.
If the procedure fails at any of the above steps, the looplet remains isolated from
the QuickLoop, and the procedure is executed again after the time-out period. If
all the steps are successfully completed, the looplet is reinstated into the
QuickLoop by full initialization.

Any physical level errors occur, such as loss of synchronization or laser fault.
The frequency of LIPs received from a port exceeds a threshold.
A port fails to become the Loop Initialization Master within a time-out period
after LIPs are either received from or sent to the port.
A port does not receive a loop initialization sequence back within a time-out
period after the sequence is sent.
FL_Port enters OPEN-INIT and becomes the Loop Initialization Master.
determined whether the looplet can be fully initialized within a time-out
period.
