Error Can Be Caused if Port Speed is Changed Simultaneously for All
Ports of a Director 2/140
In the Director 2/140, changing Port Speed on all Ports of a Director 2/140 can
cause an HAFM Resource Unavailable error, and the port speed changes
may not be completed.
Workaround
If this error occurs when trying to change port speed of all ports on a Director
2/140, you can change the port speeds individually.
Adding a Defective ISL Connection May Cause all ISLs to Segment
Between the Two Switches or Directors
Adding a defective ISL (due to defective cable, optics, or port) between edge
switches or directors may result in all the ISLs between the edge switches or
directors becoming segmented.
Workaround
Should the ISLs between two edge switches or directors become segmented as a
result of adding an ISL between them, disconnect the added ISL, allow the fabric
to be rebuilt and then troubleshoot the problematic ISL. This can be avoided by
using known good cables and performing port diagnostic tests before connecting
an ISL.
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 will
be evident when the HAFM application 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
Should this condition occur, the configuration of the edge switch or director must
be restored, and the IP address must be restored. Also, all licensed features will
need to be reactivated by entering the license keys again.
