Firmware Summary
Fibre Channel Protocol-Related Differences
Table B-2 summarizes Fibre Channel protocol-related differences
between the E/OSc 8.0, E/OSn 6.0, and E/OSi 4.6 firmware versions.
Misaligned word
generation
Misaligned words not generated. Misaligned word is generated
when the port state machine
(PSM) transitions from inactive
to active state or from active to
inactive state. This anomaly has
no effect on Fibre Channel
device behavior.
Misaligned words not generated.
Flexible partition
(FlexPar) feature
support
Flexpar feature not supported. Up to four FlexPars supported
for each Intrepid 10000 Director
chassis.
Flexpar feature not supported.
Maintenance port
access
For directors, one 9-pin, RS-232
serial port shared between two
CTP cards. Port-attached device
communicates only with the
active card. For fabric switches,
one 9-pin, RS-232 serial port per
switch.
Each CTP card has an
independent 9-pin, RS-232 serial
port that provides access to
engineering-level interfaces.
Maintenance mode and
command line interface (CLI)
available through the active CTP
card port.
One 9-pin, RS-232 serial port
per SAN router.

Node port (N_Port) ID
assignment
N_Port ID assigned based on
port number plus offset of four.
Device attached to port nn
obtains N_Port ID of
dd(nn+4)xx, where dd is the
switch domain ID and xx is
hexadecimal 13.
N_Port ID assigned based on
port number. Device attached to
Port nn obtains N_Port ID of
ddnnxx, where dd is the switch
domain ID and xx is
hexadecimal 13.
N_Port ID assigned based on
port number. Device attached to
Port nn obtains N_Port ID of
ddnnxx, where dd is the switch
domain ID (always 01) and
xx is hexadecimal 13.
Exchange switch
support (ESS)
sequence transmission
ESS not transmitted until fabric
shortest path first (FSPF)
algorithm obtains best hop to
target domain.
ESS transmitted at the moment
adjacency to the target domain is
detected (link at FSPF FULL
state). Therefore, ESS always
transmitted sooner for an
Intrepid 10000 Director.
ESS transmitted only in
response to an ESS received
from another fabric element.
