HP StorageWorks Director and Edge Switch Release Notes (09.09.09) (5697-0776, November 2010)

Devices in mixed fabric may not log in after power cycle if RD zones are
configured
In a mixed fabric (containing both M-series and B-series switches) in McDATA Fabric interop mode,
devices are unable to log in to an Edge Switch or Director that is Power On Recycled (POR) when
RD zones are configured. This is evident when the name server database is empty and the F_Ports
do not come online. To enable the devices to log in, either issue the cfgsave command from a
B-series switch in the fabric, or delete the RD zones locally using the CLI.
Fabric initialization error may occur
A fabric initialization error may occur when a two-switch fabric has only one ISL between them, and
the ISL is blocked and then unblocked. When this occurs, the fabric is not formed. To correct this, set
one of the switches offline and then back online. This is disruptive to devices connected to the switch
that is set offline, so you should plan accordingly.
Segmented ISL may be reported incorrectly in mixed fabric
B-series switches display a Gx_Port connection as Loopback (when they should display a segmented
condition) for M-series Edge Switch 2/24 or McDATA Sphereon 4500, M4700, or M4400. To avoid
this, configure the port as a G_Port (not a Gx_Port) when attaching to a B-series switch.
PDCM may revert to earlier configuration after power cycle
The PDCM configuration is set to the previously active configuration instead of the configuration in
the IPL file when all of the following conditions apply:
• A switch is managed with HAFM/EFCM Management Style configured to FICON Management
Style
• The Prohibit Dynamic Connectivity Matrix (PDCM) is configured with Active=Saved disabled
• The HAFM/EFCM Management Style is changed to Open Systems Management Style
• The switch is power-cycled
Workaround : If the switch is configured as described above, review and modify the PDCM as needed
after a power cycle.
Ethernet port may become unresponsive
After upgrading firmware from 9.6.x or later, the Ethernet port may become unresponsive, which
prohibits management of the switch.
Workaround : If you encounter this problem, remove the Ethernet cable from the port and then reconnect
it. If this does not work, execute an IML by pushing the IML button on the switch, which resets the
Ethernet port.
Open Trunking function may operate slower when Reroute Delay is enabled
When Open Trunking is in use, Reroute Delay is enabled, and traffic is rerouted by the Open Trunking
function, the anticipated changes in data flow are not correctly accounted for in the Open Trunking
algorithms. This can cause delays in rerouting traffic by Open Trunking.
