Workaround
Use these steps to clear the incident alerts.
1. At the HAFM Hardware View, click the port module to open the Port Card
View.
2. Right-click on the port with the yellow triangle icon, and choose Clear Link
Incident Alert(s).
Support for speed Auto-Negotiate
Auto-negotiate is supported. However, HP recommends that the port speed for
E_Ports (for Interswitch Links, or ISLs) be set to a specific port speed (1Gb/sec or
2Gb/sec, as appropriate for the speed of the directors or edge switches being
connected) instead of to Negotiate. Using a specific port speed decreases the time
for a fabric build in response to some perturbation event in the fabric. Similarly,
setting a specific port speed for N_Ports also decreases fabric build time.
However, setting a specific port speed for N_Ports is not required.
There are a few older HBA devices that do not always succeed in logging in to a
switch port when the port speed is set for auto-negotiate.
Workaround
If an older HBA has difficulty logging into a switch port that has its port speed
configured as Negotiate, configure that port speed to 1Gb/sec or 2Gb/sec
according to the operation speed of the HBA connected to that port.
Ports may accumulate spurious events
A port may accumulate Invalid transmission word and Bit-Error Threshold Link
Incident events when a transceiver is poorly seated, resulting in a poor ground
connection.
Workaround
Reseating the optical transceiver corrects the problem.
IML is required after performing a configuration reset
If a Reset Configuration is performed on a Director 2/140 to reset the director to
factory configuration, you must perform an initial machine load (IML) to
complete the process. This is done by pressing the white button on the front of
either CTP card for more than three seconds. This can also be accomplished by
turning the power to the Director 2/140 off and then back on.
