HP StorageWorks Fabric OS 6.3.3d Release Notes (5697-0493, May 2010 - includes all 6.3.0x versions)

FICON
• For the DC SAN Backbone Director, FICON is not allowed with a 48-port blade in the Default
Logical Switch. All ports on a 48–port blade must be assigned to a user-defined Logical Switch
to use them in a FICON enabled switch.
• The DC04 SAN Director is not supported for FICON Cascading in interopmode 2 or 3 for use in
mixed fabrics with M-EOS platforms.
NOTE:
For information about specific versions of Fabric OS support for FICON, see the B-series FICON
Connectivity Stream.
Additional considerations for FICON environments
This section provides supplemental information for users deploying Fabric OS-based platforms in
FICON environments:
• The HP StorageWorks DC04 SAN Director is supported for FICON only in Brocade Native Mode
(interopmode 0), and therefore is not supported for interoperability with M-EOS platforms.
• For FICON environments, the 8-link ICL license is qualified only for DC04 SAN Director to DC04
SAN Director or DC04 SAN Director to HP StorageWorks DC SAN Director configurations. It is
not qualified for DC SAN Director to DC SAN Director configurations. For DC SAN Director to
DC SAN Director configurations, use the 16-link ICL license, which is FICON qualified.
• Multiple 10 Gb/sec ISLs and FCIP links can load-share between cascaded FICON directors/switches
but do not load balance in a FICON configuration.
• For HP StorageWorks 8/40 or 8/80 SAN Switches with factory installed Fabric OS 6.3.1a that
will be configured in FICON environments, there is an issue with PID assignment. See “Miscel-
laneous” on page 38 for further details on this issue and how to avoid it.
• For FICON environments currently running a 6.1.x version of Fabric OS, planning to upgrade to
6.3.0d, the 6.2.0e_upgrade version of Fabric OS should be used as the interim upgrade step
between 6.1.x and 6.3.0d to avoid a specific issue. For further details, see the 6.2.0e_upgrade
Read Me First document. To access this, see the “Firmware upgrade instructions” on page 24,
substituting “6.2.0e_upgrade” for “6.3.0d” to access the Read Me First documentation.

CommentsArea
Depending on the fulfillment method, the default fill word may be set to IDLE or ARB(FF).
The fill word is changed using the portcfgfillword command. Although the fill word
is always IDLE when ports log in at less than 8 Gb/s, executing the portcfgfillword
command is disruptive regardless of the speed at which the ports log in.
8 Gb/s Links
Non-disruptive Hot Code Load is supported only on director class switches (4/256, DC
SAN Backbone, and DC04 SAN Directors). Non-disruptive Hot Code Load is not supported
on the 8/40, 8/80, 400 MP Router, and 1606 SAN Extension switches. IFCCs may result
if traffic is not stopped while downloading firmware.
