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
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).
Workaround
If this condition occurs, the configuration of the edge switch or director must be restored, and the IP address must be restored. Also, all licensed features need to be reactivated by entering the license keys again.
SNMP issues
SNMP traps warmStart and coldStart are not always received across Ethernet switches.
Workaround
None.
