HP StorageWorks Director and Edge Switch Release Notes (09.09.08) (5697-0720, October 2010)

Reinstalling feature licenses
Feature licenses (or keys) must be reinstalled after performing a factory reset on an Edge Switch or
Director to regain use of the licensed features (for example, SANtegrity Binding).
CTP controls port lights
Port lights on the Edge Switches and Directors are controlled by the CTP. Certain activities, such as
firmware updates, IPLing the CTP, and switching over to the backup CTP (Director) can turn off the
port lights momentarily until control is reasserted by the CTP. Fibre Channel traffic is not affected
during these times.
Full Fabric capability for Edge Switch 2/12
Unlike other Edge Switch and Director products, a PFE key controls Edge Switch 2/12 E_Port-to-E_Port
connections. After purchasing and installing the feature key, you can configure E_Port connections
on any of the active ports.
The feature key includes distance support. With firmware 06.00.00 or later, the Edge Switch 2/12
ships with five BB_Credits allocated to each port. After activation of the Full Fabric feature on the
switch, each port has 12 BB_Credits allocated to support up to 12-km links at 2-Gb/s speed.
Support for speed autonegotiate
Autonegotiate is supported. However, HP recommends that E_Ports (ISLs) be set to a specific port
speed (1 Gb/s, 2 Gb/s, or 4 Gb/s, as appropriate, for the speed of the Edge Switches or Directors
being connected) instead of to Negotiate. Specifying a port speed decreases the fabric build time in
response to a perturbation in the fabric. Specifying a port speed for N_Ports also decreases the fabric
build time, but it is not required.
Older HBA devices do not always succeed in logging in to a switch port when the port speed is set
to Autonegotiate.
Workaround: If an older HBA has difficulty logging in to a switch port with the port speed set to
Negotiate, set the port speed to 1 Gb/s, 2 Gb/s, or 4 Gb/s, according to the operating speed of
the HBA connected to that port.
SNMP object returns incorrect value
The SNMP object t11NsInfoSubsetTableLastChange does not return the proper value of the
last change in the Name Server timestamp, but instead returns the value 0 days
00h:00m:00s.00th.
Preferred Path may be cleared when port card is replaced
When replacing a port card module, a configured Preferred Path with a source port that is part of
the newly installed port card module is cleared. A configured Preferred Path with an exit port that is
part of the newly installed port card module is not cleared. If the Preferred Path entry is cleared when
a port card module is replaced, the Preferred Path must be reentered.
