Important Notes
This section provides information you should be aware of when running Fabric
OS v3.1.2.
OS Requirements
HP recommends using the latest software release versions to get the greatest
benefit from the SAN.
Mixed Fabric Environment with Different Switch Platforms
Fabric OS v2.6.2, v3.1.2, and v4.2.x introduced a new switch PID format:
Extended Edge PID (Format 2). Extended Edge PID is useful if you introduce a
Fabric OS v4.2.x switch into a fabric consisting solely of Fabric OS v2.x/v3.x
switches. Before adding a Fabric OS v4.2.x switch to such a fabric, refer to the
HP StorageWorks Fabric OS 4.2.x Procedures User Guide for information on the
Extended Edge PID format.
Note: Switches must operate with Fabric OS v2.6.2, v3.1.2, or v4.2.x to use the
Extended Edge PID format.
If Extended Edge PID is set (before a downgrade from the current Fabric OS
release to an earlier Fabric OS release that does not support the Extended PID
format), PID needs to be set back to a supported format, such as Core PID
(format 1) or native PID (format 0).
Advanced Web Tool Updates
The following is a list of Advanced Web Tools updates for this release:
■Advanced Web Tools integrated management Graphical User Interface (GUI)
recognizes HP StorageWorks switches released after Fabric OS v3.1.2 as
generic 16-port switches.
■When using a mixed fabric—that is, a fabric that contains v4.x, v3.x, and v2.x
switches—HP recommends that you use the most advanced switches to
control the fabric. For example, use the v4.x switches as the primary Fibre

Important Notes
8 SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
Channel Switch (FCS), as the location to perform zoning tasks, and as the
time server. HP also recommends that you use the most recently released
firmware to control the fabric.
Two-Domain and Four-Domain Fabric Licensing
If your fabric includes a switch with a license for a limited number of switches in
the fabric and the fabric exceeds the limit, Advanced Web Tools allows a 45-day
grace period during which you can still monitor the switch. Advanced Web Tools
periodically displays warning messages.
These messages warn you that your fabric size exceeds the supported switch
configuration limit and tells you how long you have before Advanced Web Tools
will be disabled. After the 45-day grace period, you will no longer be able to
launch Advanced Web Tools from the switch if it still exceeds the limit.
Note: Two-domain and four-domain fabric licensing is applicable only to 2 Gbps
switches.
Switch View Display Issue
If you frequently enable or disable a switch or perform a power cycle, the Switch
View may not display properly. Launching other Advanced Web Tools
components might then cause a browser crash.
Workaround: Upgrade your Java Plug-in to 1.4.1_06 or later, if you are
running Windows XP.
Installing Mozilla 1.4 on Solaris 8 and Solaris 9
For instructions to install Mozilla 1.4 on Solaris 8 and Solaris 9, go to the web
site:
http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.4/mozilla-sparc-sun
-solaris2.8_1.4.readme
Mozilla Browser Support for Switch Admin Module
The Mozilla browser does not support the Switch Admin module properly in
Fabric OS v2.6.x. In Fabric OS v2.6.2, a warning message is displayed. No
warning message is displayed in other 2.6.x versions.
Workaround: Use Netscape 4.7.7 or later.

Fabric OS v3.1.2 Important Notes
Table 3 lists important information you should be aware of regarding Fabric OS
v3.1.2.
Table 3: Fabric OS v3.1.2 Important Notes
Area Description
Fabric Watch, e-mail
alert error message When enabling e-mail alerts in Fabric Watch and an event occurs, the message ErrLog: Error Level=3 [(null)] is captured to the
system error log. This message is from SMTP and can be ignored.
FARP requests Fabric OS v2.x and v3.x do not support FARP requests, only ARP requests.
When using IP over Fibre Channel, confirm that all host HBAs support ARP
requests and issue ARP requests.
License removal When a user removes a license from the switch, the feature is not disabled
until the switch is rebooted or a switch disable or enable is performed.
Security, PKICERT
utility Before using the PKICERT utility to prepare a Certificate Signing Request (CSR), ensure that there are no spaces in the switch names of any switches
in the fabric. The web site that processes the CSRs and generates the digital
certificates does not accept switch names containing spaces; CSRs that do
not conform to this requirement are rejected.
Zoning To use zoning in a non-RCS (Reliable Commit Service) mode fabric (that is,
in a fabric containing switches with firmware versions other than v2.6.x or
later, v3.1 or later, and v4.1 or later) install all appropriate zoning licenses
on all the switches in the fabric before attempting to bring a switch in to the
fabric.
If the zoning license is to be removed, the user must make sure it is
reinstalled properly on the affected switch before attempting the
cfgenable zoning operation. Failure to follow these steps can cause
inconsistency of zoning configuration on the affected switches if a zoning
operation is attempted from a remote switch in the fabric. On the affected
switches, an error message appears on the console or Telnet session
indicating that the zoning license was missing. The message can also be
seen by issuing the errShow or errDump command.

New Command in v3.1.2
12 SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
New Command in v3.1.2
pathInfo
Displays routing and statistics info along a path.
Synopsis
pathInfo [domain], source port] destination port] [,”-r”]
Availability
root admin
Description
The pathInfo command displays detailed routing information from a source
port (or area) on the local switch to a destination port (or area) on another switch.
This routing information describes the exact path that a user data stream takes to
go from the source to the destination. If the user specifies the use of inactive ports
or a path through a switch that does not have active routing tables to the
destination, pathInfo describes the path that would be used if the ports were
active. If the user specifies a destination port that is not active, then pathInfo
uses the embedded port as the destination.
For switches with blades, the ingress and egress points are specified as area
numbers. For a non-bladed switch, ingress and egress points are specified as ports.
This agrees with the representation shown in the switchShow command. The
pathInfo command can also provide, upon request, statistics on every traversed
ISL. The routing and statistical information are provided by every switch along
the path, based on the current routing tables information and statistics calculated
continuously in real time. Each switch represents one hop.
Other options allow the collection of information on the reverse path or on a
user-selected path (source route).

New Command in v3.1.2
13SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
For each hop, the routing information output includes the following:
For each hop, statistics are broken down into basic and extended. They are
reported below the routing information, separated into input port statistics and
output port statistics. For each port, they are further separated into transmit and
receive statistics. Statistics are not reported for the embedded port. Some values
are measured over multiple time intervals. For example, the output line utilization
in bytes per second is calculated over both a 1-second period and over a 64-second
period. this gives an idea of both the current line utilization and the utilization
over a longer period. The time interval is listed in parentheses after the value’s
description.
Maximum Hop Count
The pathInfo command uses a special frame that is sent hop-by-hop from the
source switch to the destination switch, collecting routing and statistical
information at every hop. To prevent such a frame from looping forever when an
error occurs, the command specifies a maximum number of hops for the frame to
traverse.
The hop count includes all hops in the direct path from source to destination, and
also all the hops in the reverse path, if the tracing of the reverse path is requested.
The default value for the maximum hop count is 25.
Hop The hop number (the local switch is hop 0.
In Port The port (or area) from which the frames come. For hop 0,
the source port. For a switch with blades, this is specified s
the area number; otherwise, as the port number.
Domain ID The domain ID of the switch.
Name The name of the switch
Out Port The output port that the frames take to reach the next hop.
For the last hop, this is the destination port or area. For a
switch with blades, this is specified as the area number;
otherwise, as the port number.
BW The bandwidth of the output ISL in Gbps. It does not apply
to the embedded port.
Cost The cost of the link used by FSPF routing protocol. It
applies only to an E_Port.

New Command in v3.1.2
14 SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
Basic Statistics
Basic statistical report variables give an indication of ISL congestion along the
path. They include the following:
Extended Statistics
Extended statistics report variables of general interest. They include the following:
Reverse Path
In general, the path from port A on switch X to port B on switch Y might be
different from the path from port B to port A. The difference could be in the links
traversed between the same sequence of switches, or the reverse path might even
involve different switches. The trace reverse path option allows the user to
determine both routing and statistical information for the reverse path, in addition
to those for the direct path.
Source Route
The source route option allows the user to specify a sequence of switches or ports
(or areas) that the pathInfo frame must follow to reach the destination.
Therefore, the path might be different from the one the actual traffic will take from
source to destination.
B/x Bytes per second.
Txcrdz The time in milliseconds that the port has been prevented from
transmitting frames due to lack of buffer-to-buffer credit. This
is an indication of downstream congestion. Note that other
commands (portShow, for example) may express this value
in units other than milliseconds.
F/x Frames per second.
Words Total number of four-byte Fibre Channel words.
Frames Total number of frames.
Errors Total number of errors that might cause a frame to be received
incorrectly. This includes CRC errors, bad-EOF errors,
frame-truncated errors, frame-too-short errors, and encoding
errors inside a frame.

New Command in v3.1.2
15SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
The source route is expressed as a sequence of switches, a sequence of output
ports (or areas), or a combination thereof. The next hop in the source route is
described by either the output port (or area) to be used to reach the hop or the
domain ID of the next hop.
The source route can specify a partial route from source to destination—in which
case the remaining hops are chosen as the path from the input port (or area) on the
first hop not listed in the source route to the destination—a full route, or an
arbitrary route across the fabric. The maximum hop count is enforced.
If the source route does not specify all the switches along a section of the path, a
further option allows the user to specify a strict path versus a loose path. A strict
source route requires that only the specified switches be reported in the path
description. If two switches are specified back-to-back in the source route
descriptor but are not directly connected, the switches in between them are
ignored. For a loose source route, the switches in between are reported. The
concepts of strict and loose route apply to the portions of the path described by
domains, not to the part described by output ports or areas.
Operands
The following operands are allowed:
domain The ID of the destination domain.
source port The port (or area) whose path to the destination domain is
sought. The embedded port (-1) is used by default. For a
switch with blades, the destination is specified as the area;
otherwise, as the port. If the source port is given as -1 with
no additional arguments, then basic statistics are displayed
for the route.
destination
port A port on the destination switch. The pathInfo command returns the state of the port (or area). The embedded port (-1)
is used by default or if the user specifies a destination port
that is not active. For a switch with blades, the destination is
specified as the area; otherwise, as the port.
–r Show reverse path in addition to the forward path in the
output display.

New Command in v3.1.2
16 SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
If no operands are specified, pathInfo displays a menu in which the following
parameters can be provided:
max hops The maximum number of hops that the pathInfo frame is
allowed to traverse. The default is 25.
domain The ID of the destination domain. This is a mandatory
parameter; there is no default.
source port The port whose path to the destination domain is sought. It
can be an F_Port or an E_Port. The embedded port (-1) is
used by default. For a switch with blades, this is specified as
the area; otherwise, as the port.
destination
port A port on the destination switch. The pathInfo command returns the state of the port and all requested statistics for the
port. The embedded port (-1) is used by default or if the
specified destination port is not an existing active port. For a
switch with blades, this is specified as the area; otherwise, as
the port.
basic stats Requests the reporting of basic statistics on every link. There
is no default.
extended
stats Requests the reporting of extended statistics on every link. There is no default.
trace reverse
path Provides path information from the destination port to the source port. There is no default.
source route Specifies a sequence of switches or ports that the
pathInfo frame should traverse. Note that if an output port
(or area) to the next hop is specified, then the user is not
prompted for the domain of the next switch; that is
determined by the port (or area) specified. There is no
default.
strict source
route Specifies that the source route must be followed strictly as indicated, skipping possible intermediate switches. When
using this option, the source route must be specified using
domain numbers, rather than the output port.
timeout The maximum time allowed to wait for the response. The
default is 10 seconds.

Commands Modified in v3.1.2
The following commands have been modified in v3.1.2:
■quietMode
■switchShow
quietMode
This command sets and clears shell quiet mode.
Synopsis
quietMode [new mode]
Availability
All users (display)
Admin (set and clear)
Description
This command affects the output displayed on the switch’s console (serial port or
Telnet session).
By default, quiet mode is turned off and all switch tasks can send output to the
console. Some output is caused by asynchronous events, such as the fabric
reconfiguring, or by devices logging in.
When quiet mode is turned on, only output produced by shell commands is
shown; all asynchronous output produced by other tasks is suppressed. This is
useful when driving a Telnet session via a script that might not expect
asynchronous output.
Operands
The following operand is optional:
newMode 0to clear quiet mode (all tasks can print to the console)
1to set quiet mode (only shell commands can print)
