Anleitung Zusammenfassung
SAN Backbone Director, HP StorageWorks DC04 SAN Director Switch, or HP SN8000B
SAN Director switches.
Area
Comments
Cascading
There are special configuration considerations for environments with three or more switches
(domain IDs) in a FICON fabric. Seek assistance from service support to ensure proper
configuration.
Cascading
Fiber ICL configurations (with HP SN8000B SAN Directors) supported for FICON are the
same as the supported configurations for copper ICLs (with HP StorageWorks DC SAN
Backbone Director and HP StorageWorks DC04 SAN Director).
Cascading
Encryption and compression is supported on IP links but not on Fibre Channel ISLs.
CUP
The switch name is replaced with underscores ( ____ ) after the first time CUP (FMS mode) is
enabled. Use the switch configuration panels to reset the switch name.
FCIP
VEX ports are not supported on the HP 1606 SAN Extension Switch and HP DC SAN Director
Multiprotocol Extension Blade in a FICON environment.
FCIP
When performing multiple cabling changes to the SAN fabric in a FICON Emulating FCIP
Tunnel configuration with the HP 1606 SAN Extension Switch or HP DC SAN Director
Multiprotocol Extension Blade, either disable all of the FCIP Tunnels or issue the switch disable
command on all FCIP interconnected switches to avoid IFCCs in a mainframe environment.
Issuing either a switch disable or an FCIP Tunnel disable command allows the FCIP FICON
Emulation processing state-machine to execute an orderly cleanup process and allow normal
activation of the new configuration. When all cabling and Traffic Isolation Zone manipulations
have been completed, enable the switches or the FCIP Tunnels.
FCIP
A disabled XGE or GE port is re-enabled after a code upgrade/downgrade. To prevent
XGE/GE ports from being re-enabled after a code load they should be persistently disabled.
Firmware Downloads
Non-disruptive Hot Code Load is supported only on director class switches (HP StorageWorks
DC SAN Backbone Director, HP StorageWorks DC04 SAN Director Switch, or HP SN8000B
SAN Director switches. Comprehensive non-disruptive Hot Code Load is not supported on
the HP 1606 SAN Extension Switch or HP StorageWorks DC SAN Backbone Director, HP
StorageWorks DC04 SAN Director Switch, or HP SN8000B SAN Director switches with an
HP DC SAN Director Multiprotocol Extension Blade since the FCIP tunnels will go down for
10-15 seconds and all traffic in the tunnels will be disrupted. IFCCs may result if traffic is not
stopped while downloading firmware.
Firmware Downloads
The CUP device must be varied offline to all MVS partitions before starting a code load. The
CUP device can be varied back online after the code load completes. Failure to vary off the
CUP devices may result in missing interrupt.
Interoperability
When connecting an 8 Gbps or 16 Gbps capable port in a switch to an IBM Virtualization
Engine TS7700, the port must be configured to a minimum of 16 buffers to avoid IFCCs at
the channel and loss of FICON paths to the control unit. This requires the Extended Fabric
license on the switch.
Manageability
Port Fencing should be used to avoid taking ports down for normal fabric events. The
recommended fencing criteria and settings are listed in Table 7 (page 36).
NOTE:
Port fencing should not be set for C3 discards.
Manageability
As a best practice for deploying Fabric OS switches and directors into a FICON environment,
verify the Fabric OS version shipped with the most current Fabric OS recommendation. HP
recommends you update all Fabric OS switches and directors to the same Fabric OS levels
for production.
Manageability
FMS must be enabled on the local switch for the remote CUP to work.
Manageability
The FICON merge wizard feature in HP Network Advisor cannot be used to merge an HP
StorageWorks 4/256 SAN Director with an HP StorageWorks DC SAN Backbone Director,
HP StorageWorks DC04 SAN Director Switch, or HP SN8000B SAN Director switches.
Manageability
When setting insistent domain ID on a switch using the FICON Configuration Wizard, the
switch is always taken offline and insistent domain ID set, even if insistent domain ID is already
set.
