HP B-series Fabric OS 6.3.2e Release Notes (5697-1816, March 2012) - includes all 6.3.2x versions

to a version later than 6.3.1c does not
affect the current mode settings.
command are persistent, and will therefore
remain at mode 1 after Fabric OS upgrade.
◦ If a pre-6.2.0d version was installed in
the factory, the default setting for all
internal and external ports is mode 0. The
setting can be changed by the user on a
port-by-port basis and will be persistent.
Upgrading to version 6.3.1a or later
does not affect the current mode setting,
with the exception of version 6.4.0b or
later as described below.
◦ If upgraded to version 6.4.0b, regardless
of what version was factory installed, all
internal ports will be set to mode 1, and
all external ports to mode 0. The setting
can be changed by the user on a
port-by-port basis and will be persistent.
0—Idle for link init, idle for fill wordModes
1—Arb(ff) for link init, arb(ff) for fill word (not supported with EVA or XP storage arrays)
2—Idle for link init, arb(ff) for fill word
3—Initially attempts mode 1 link initialization. If unsuccessful in achieving active state,
reverts to mode 2. Steady state fill word is arb(ff). (not supported with XP storage arrays
earlier than Fabric OS 6.4.0a.)
Miscellaneous
• The severity of RASLOG message AN-1003 has been raised from WARNING to ERROR in
Fabric OS 6.3.2c and later 6.3.x releases. This change allows customers to easily trap on
the event via SNMP. AN-1003 is not an actual error but an indication that there may be a
potential bottleneck device attached to the switch. Customers who do not want to be notified
of this RASLOG event should leave Bottleneck Detection disabled.
• POST diagnostics for the 8/40 SAN switch have been modified in Fabric OS 6.3.1b/6.4.0
and later releases to eliminate an INIT NOT DONE error at the end of an ASIC diagnostic
port loopback test. This modification addresses BL-1020 initialization errors encountered
during the POST portloopbacktest. During non-disruptive firmware upgrades, E_Ports in
R_RDY mode may cause some frame drops on the E_Port links.
• Modem capability for the 4/256 director is not supported in Fabric OS 6.2.0 and later.
• On the HP 8/8, 8/24, 8/40, and 8/80 SAN Switches with factory installed Fabric OS
6.3.1a, the assignment of PIDs (FCIDs) is non-deterministic. The area field of the PIDs is assigned
the first time the switch is booted up, based on the order that ports are recognized and brought
up by the system. Switch PIDs area will not be equal to port number, which may impact servers
such as FICON or static PID bind servers that need area equal to port numbers to log in to
the fabric successfully. To avoid this issue, customers can bind PIDs using the portaddress
--bind [slot_number/]port_number [16-bit_address] command prior to allowing
devices to log in to the switch. Once assigned, the PIDs are maintained across reboots and
future Fabric OS upgrades. This issue does not impact switches that do not have Fabric OS
6.3.1a factory installed. Field upgrade to a later version of Fabric OS will not resolve this
situation. For environments in which this will be an issue, the specified workaround will need
to be implemented until a future version of Fabric OS is factory installed.
• Beginning with Fabric OS 6.2.0, the data collected by SupportSave operations was greatly
expanded to include all readable registers within the ASIC. In cases where some registers
may be unused and therefore contain invalid data, a CDR-1003 error message would be
