Support For Speed Auto-Negotiate - HP StorageWorks 2/140 - Director Switch Release Note

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.
Possible switch reset after power failure or power off sequence
In extremely rare instances, after a power failure or power off sequence, an edge switch
or director configuration may be reset to factory default settings. This is evident when
HAFM is unable to communicate with the edge switch or director after being powered
on. This condition occurs because the IP address assigned to the edge switch or director
has been reset to the factory default value (10.1.1.10).
