6.3.1a and later Implemented support for modes 2 and 3 as described below. The default setting for all ports is mode 0, regardless of what Fabric OS version was previously installed. However, ports previously set to mode 1 by the user via the portcfg- fillword command are persistent, and will therefore remain at mode 1 after Fabric OS upgrade. • If version 6.2.0d or 6.3.1c was installed in the factory, the default setting is mode 1 for the internal ports and mode 0 for the external ports. The setting can be changed by the user on a port-by-port basis and will be persistent. Upgrading to a version later than 6.3.1c does not affect the current mode settings. • 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. Modes 0-Idle for link init, idle for fill word 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 HP B-series Fabric OS 6.3.2d Release Notes 33

If version 6.2.0d or 6.3.1c was in-
stalled in the factory, the default set-
ting is mode 1 for the internal ports
and mode 0 for the external ports.
The setting can be changed by the
user on a port-by-port basis and will
be persistent. Upgrading to a version
later than 6.3.1c does not affect the
current mode settings.
•
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 excep-
tion of version 6.4.0b or later as de-
scribed below.
•
If upgraded to version 6.4.0b, regard-
less of what version was factory in-
stalled, 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.
Implemented support for modes 2 and 3
as described below. The default setting
for all ports is mode 0, regardless of what
Fabric OS version was previously in-
stalled. However, ports previously set to
mode 1 by the user via the
portcfg-
fillword
command are persistent, and
will therefore remain at mode 1 after
Fabric OS upgrade.
