OS Requirements
HP recommends using the latest software release versions to get the greatest
benefit from the SAN.

Important Notes
7SAN Director 2/128 Fabric OS 4.2.x Release Notes
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: Note that in order to use the Extended Edge PID format, Fabric OS v2.6.2,
v3.1.2, and v4.2.x must be deployed together, as applicable, to the switches.
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
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 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.
If you use Advanced Web Tools to change the switch name, the HP StorageWorks
SAN Director 2/128 Telnet console prompt does not update to the new name until
a new Telnet window is opened.
If a dialog box is displayed from the Switch Admin window of Advanced Web
Tools and the user selects another dialog box from Advanced Web Tools, a
window display error occurs.
Workaround: HP recommends JavaTM 1.4.1_03.
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.

Important Notes
8 SAN Director 2/128 Fabric OS 4.2.x Release Notes
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 our domain fabric licensing is applicable only to 2 Gb/sec
switches.
Browser Window Response After Failover
A browser window might stop responding after an HA failover immediately after
a zoning configuration is enabled or disabled. It is likely that the web daemon was
terminated by the HA failover before the HTTP request was returned.
Workaround: If the HA module does not respond, close the window and
relaunch the module. If the module is locked, shut down and relaunch the Web
Tools application.
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 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.

Table 3: SAN Director 2/128 Information
SAN Director 2/128 Description
CP blade The SAN Director 2/128 CP contains electronics that provide internal
routing bandwidth, and are always active on both CPs. Removal of a CP
might affect user performance and therefore should not occur until a
replacement CP is ready to be installed.
Power supplies A fully configured SAN Director 2/128 with eight port cards and two CPs is
capable of running on a single power supply. Therefore, two power
supplies provide 2N redundancy. To maintain redundancy of AC input, one
power supply must be in an even-numbered slot and one in an
odd-numbered slot. The default configuration is for the power supplies to be
in slots 1 and 2.
Card seating Follow the procedure below to ensure that Port Cards and Control Processor
(CP) cards are properly installed into your SAN Director 2/128:
1. Install the leading edge of the CP or Port Card into the appropriate slot
on the card cage.
2. Push the front surface of the card (SFP cage side) carrier near the center
with your hand until the top and bottom ejectors engage the upper and
lower ejector plates (do not hold onto the ejectors as you push).
3. Press down on both ejectors at the same time with equal force to seat the
blade.
4. Tighten the top thumb screw first.

Table 5: Fabric OS Area Information
Fabric OS Area Description
Ethernet port IP
addresses When a SAN Director 2/128 fails over to its standby CP for any reason, the IP addresses for the two logical switches move to that CP blade's
Ethernet port. This might cause informational ARP address reassignment
messages to appear on other switches in the fabric. This is normal behavior,
because the association between the IP addresses and MAC addresses has
changed.
Extended links For 50-km extended links, you have a choice of configuring a port as an LD
port or an L1 port. LD ports maintain full link speeds of 103 Mbit/sec. L1
ports have link speeds of 99 Mbit/sec; you can configure all four ports of a
quad as L1 ports, but you can configure only one port in a quad as an LD
port.
Fabric configuration During fabric configuration, the countdown message that used to appear on
the console is removed starting with Fabric OS v2.6.2, v3.1.2, and v4.2.x.
The fabric reconfiguration message is now captured in the error log. For
details, refer to the diagnostic messages in the
HP StorageWorks Diagnostic
and System Error Messages 4.2.x Reference Guide
.

Important Notes

Fabric Device
Management Interface
(FDMI)
An HBA will be allowed to register even though the originating port is not
on the HBA's registered port list. This is intended behavior, included to test
error cases.
Fabric OS: CLI
commands, failover,
and port disable
Changing port configurations during a failover might cause ports to be
disabled. Reissue the command after the failover is complete to bring the
ports online.
Fabric OS: commands Under the root account, issuing Fabric OS commands in parallel through
scripts could cause the kernel task to consume excessive memory.
Workaround: When using scripts to issue Fabric OS commands, wait for
one command to finish before issuing another.
Fabric OS: switch
beaconing Switch beaconing is not preserved across a failover. If you start beaconing, a failover causes all lights to stop flashing.
Workaround: If this occurs, reissue the command to resume switch
beaconing.
Fabric OS: switch
reboot and blade
repair
Switch reboot will fail in the SAN Director 2/128 if there are faulty port
blades.
Note: Verify that all blades are in working order before performing a
switch reboot. Switch reboot is meant to be issued after all repairs are
complete. If you perform a switch reboot and find a faulty blade, remove the
blade and reboot will continue.
Workaround: Identify and remove the faulty blade, using the slotshow
command.
Fabric routing, Fabric
Manager: domain
overlap
Issuing a configdefault command followed by reboot or switch disable
or enable can cause the fabric to segment due to possible domain overlap.
Workaround: Before rebooting the fabric, ensure that all switches are
properly configured to avoid domain overlap between the logical switches.
Fabric Watch: e-mail
alert error message If an event occurs while Fabric Watch e-mail alerts are being enabled, the message ErrLog: Error Level=3 [(null)] is captured to the
system error log. This message is from SMTP and can be ignored.
Firmware download During a firmware download, rebooting or power cycling the CPs could
corrupt the compact flash.
CAUTION: Do not attempt to power off the CP board during firmware
download, to avoid high risk of corrupting your flash.
Table 5: Fabric OS Area Information (Continued)
Fabric OS Area Description

Important Notes
16 SAN Director 2/128 Fabric OS 4.2.x Release Notes
Firmware download Fabric OS v4.1.x and v4.2.x nondisruptive firmware download allows for
firmware downgrades and upgrades; however, you might see warning
messages such as the following:
0x239 (fabos): Switch: 0, Info PDM-NOTFOUND, 4, File not
found
(/etc/fabos/mii.0.cfg)
These warnings can be ignored.
HA switch reboot
failure When a switch reboot or a failover occurs before POST is complete, the HA resynchronization is disrupted. HA does not resynchronize until POST
completes.
CAUTION: Allow POST to complete before performing a switch reboot or
failover, to avoid disruptive failover.
Invalid Gateway IP
address error message The user sees the following message on the console during startup when the Ethernet IP and Gateway IP addresses are set to the defaults:
SIOCADDRT: Invalid argument.....ip.c:311:Invalid gateway
IP address 0.0.0.0
This is a display issue only and does not affect the functionality of the
switch.
IP addresses CAUTION: Do not set a switch or CP IP address for the Ethernet interface to
0.0.0.0.
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.
LTO 2 tape drive
support When using the LTO 2 tape drive, the user must enter the following command on both Fabric OS v3.x and v4.x:
switch> portcfggport port# where drive is plugged in
This allows the tape drive to function in point-to-point mode rather than in
loop mode.
OS hardware Bringing up port blades during a failover could cause the port cards to
come up in a disabled state. This is a rare occurrence; when it happens,
bring up the port blade again, after the failover on the SAN Director
2/128.
rsh and rlogin The programs rsh and rlogin are not supported in this release. If you try
to use an rsh or rlogin client, Fabric OS rejects the login attempt;
however, because most rsh and rlogin clients continue to retry the login
for several seconds before timing out, your system appears to hang.
Security: default
password length The initial login prompt for a switch accepts a maximum password length of eight characters. Any characters beyond the eighth are ignored.

Important Notes
17SAN Director 2/128 Fabric OS 4.2.x Release Notes
Security: empty
policies CAUTION: If Telnet, API, and serial port access policies are empty, the user will not be able to communicate with the switch.
Workaround: Contact your switch provider for the recovery procedure.
Security: error counter Telnet security errors that arrive in quick succession are recorded as a single
violation by the telnet error counter. For example, a login error from a host
whose IP address is 192.168.44.247 is logged as follows:
Security violation: Login failure attempt via
TELNET/SSH/RSH. IP Addr: 192.168.44.247
If another login violation occurs immediately, the message remains the
same and only the error counter is incremented.
Security: fabric
segment When two secure fabrics are continuously joined and separated while the CPU is under heavy load, the fabric segments after approximately 30
cycles.
Security: FCS list Adding switches to the FCS list does not automatically join the switches in a
secure fabric. Add the switches to the FCS list of the new switches and the
target fabric. Reset the version stamp to 0 and either reset the E_Ports or
perform a switch disable and enable for the switches to join.
Security: HTTP policy If HTTP_Policy is empty, you will not be able to log in and will receive a
Page not found error. This is expected behavior for this policy.
Security: invalid
certificate Web Tools and Fabric OS are not consistent in how they report switch certificate status. Web Tools reports a valid certificate with extra characters
appended to it as invalid, whereas Fabric OS accepts the certificate and
allows a secmodeenable command to complete successfully.
Security: PKICERT
utility, CSR syntax 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.

PKICERT v1.0.6 is the most current version of the PKICERT utility.
When running the PKICERT utility to install switch certificates in a fabric that
did not previously contain switch certificates and now includes a SAN
Director 2/128, select the option to specify that certificates are installed on
only those switches that do not currently contain certificates. SAN Director
2/128s are delivered with switch certificates preinstalled. Switches that
were originally shipped with Fabric OS v2.5, v3.0, and v4.0 and have
never installed and enabled Secure Fabric OS do not have certificates
installed.
If you need to reinstall switch certificates in a SAN Director 2/128, follow
these guidelines:
■The host running PKICERT v1.0.6 must be connected to a proxy
switch running Fabric OS v2.6.2, v3.1.2, or v4.2.
■All switches in the fabric other than the SAN Director 2/128 can
run v2.6.1, v3.1, v4.1 or newer firmware.
Security: selectelnet If you try to log in to a switch through a sectelnet client while that switch is in
the process of either booting or shutting down, you might see the message,
Random number generation failed. The message is printed by the
sectelnet client because the switch Telnet service is not running (the service
has either already been shut down (if the switch is shutting down), or is not
yet established (if the switch is booting). If the switch is booting, wait a few
seconds and try again.
Security: secure mode If an upgrade from Fabric OS v4.0 to v4.1 or v4.2 is performed, followed
by a downgrade to Fabric OS v4.0 and upgrade back to Fabric OS v4.1 or
v4.2, the switch password state is reset and prompts the user for new secure
mode passwords.
Security: secure mode,
passwd Telnet CAUTION: Using the passwd Telnet command in secure mode to change the password results in all sessions using that password being logged out,
including the session that changed the password.
This is expected behavior. The session terminates if you change the
password in secure mode.
Security: SLAP counter The SLAP counter is designed to work when all the switches in the fabric are
in secure mode. All the switches in the fabric must be in secure mode for
accurate SLAP statistics.
Security: SSH login To properly connect SSH login, wait for secure mode to complete before
rebooting or performing HA failover on the SAN Director 2/128. If secure
mode is enabled and a reboot occurs before secure mode completes, SSH
login does not connect and goes to the wrong MAC address, because the
active CP changes after an HA failover.

Important Notes
19SAN Director 2/128 Fabric OS 4.2.x Release Notes
Single domain The SAN Director 2/128 can be configured only as a single domain, as
opposed to two logical domains in the Core Switch 2/64. In other words,
all port blades and slots are a part of that single switch.
WWN card FRU
repair If an HA failover or power cycle occurs during a FRU replacement on the WWN card, the SAN Director 2/128 becomes nonoperational.
CAUTION: When performing a FRU replacement on a WWN card,
complete the FRU procedure before attempting an HA failover or power
cycling the chassis.
Zoning: license 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, v3.1,
and v4.1), HP recommends that all appropriate zoning licenses be installed
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 (or by issuing the errShow or errDump
command), indicating that the zoning license is missing.
Zoning: domain ID Domain 0 in a zoning configuration file is invalid but was not previously
enforced.
Workaround: Prior to upgrading a switch to Fabric OS v4.2.x, ensure that
the fabric's zoning configuration does not contain domain ID 0, which is
used for zoning. This is specific only to 4.x switches.
