FW 07.01.02/HAFM SW 08.06.00 HP StorageWorks Director Release Notes (AA-RTDVH-TE, August 2005)

Workaround
Use these steps to clear the incident alerts.
1. At the HAFM Hardware View, click the p or t module to open the Port Card View.
2. Right-click o
n 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 specificportspeed(1Gb/sec or 2Gb/sec,as
appropriate for the speed of the directors or edge switches being connected) instead
of to Negotiate.Usingaspecific port speed decreases the time for a fabric build in
response to some perturbation event in the fabric. Similarly, setting a spec ificportspeed
for N_Ports also decreases fabric build time. H owever, setting a specificportspeedfor
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 p ort speed is set for auto-negotiate.
Workaround
If an older HBA has difficultyloggingintoaswitchportthathasitsportspeed
configured as Negotiate,configure that por t speed to 1Gb/sec or 2Gb/sec according to
the operation speed of the HBA co nnected to that por t.
Ports may accumulate spurious events
AportmayaccumulateInvalid transmission word and Bit-Error Threshold Link Incident
events when a transceiver is po orly 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 af ter 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).
