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, 2Gb/sec, or 4Gb/sec according to the operating speed of the
HBA connected to that port.

Issue
For Edge Switches, the alias database persists after
a configuration reset, where it should be cleared.
In a FICON environment, PDCM is reset to default
following activating Open Trunking.
QPM installed in a director, a cable move followed
by a port speed change under specific conditions
may cause an erroneous entry in the nameserver
for a disabled port. The sequence of events that
could cause this are: 1) a QPM is configured with
all port speeds set to burst mode 2) there are active
links on an odd number port (1 or 3) and on the
even number port that is not its corresponding
sustain mode port (2 or 0, respectively). 3) the
link to the odd numbered port (1 or 3) is moved
to its corresponding sustain mode port (0 or 2,
respectively) 4) the port speed for the other even
numbered port is changed to sustained mode 5)
the entry for the odd number port that was moved
(disconnected) may re-appear in the nameserver
In a FICON environment, if a connected device
has zero Buffer-Buffer (BB) credits, a PLOGI to that
device from other devices may fail unless the BB
credits recover.
Determining current version
This section describes how to determine the current version of firmware for an Edge Switch or Director
using the HAFM, HAFM Basic, or the CLI.
Using HAFM
To determine the current version using HAFM:
1. Open the Element Manager for the Edge Switch or Director.
2.
Select Product > Properties from the menu bar.
The firmware version appears in the dialog box.
Workaround
The alias database can be successfully cleared through
the CLI and EFCM basic.
Save the PDCM configuration before activating Open
Trunking, and activate the saved PDCM after activating
Open Trunking.
If this is issue is encountered, configure both the even
ports of the QPM card to sustained mode instead of
configuring only one.
Blocking and unblocking the switch port of the device
will allow the PLOGI to succeed.
