HP StorageWorks Multi-protocol Router XPath OS 7.4.1d Release Notes (AV-RW5LM-TE, March 2007)

Issue
Description
GNU telnet client
GNU telnet client sessions on certain workstations (for example, Sun Solaris) will be
disconnected from XPath OS upon pressing Ctrl-C twice in succession. This is in contrast
to B-Series Fabric OS, on which the same telnet client and the same key sequence does
not cause a session disconnect.
GNU telnet clients used with the UNIX® tee utility might be disconnected unexpectedly as
well.
Workaround:
Use /usr/bin/telnet instead of /usr/gnu/bin/telnet.
Root reboot co
mmand
vs. admin user
reboot
command
Users should never reboot the system from the root account using the reboot command,
or data might b
e lost. To safely reboot the system, log in as root and change to admin
by entering a
dmin at th e root prompt. When you are at the admin shell, execute the
reboot comma
nd.
FA zoning
A private host attached to a Fabric OS switch might not be able to discov er FA targets on a
MP Router due to the length of the host’s HBA PLOGI retry timeout. You can reduce the
timeout value to resolve this issue.
FA and QuickLoop zone
management
While zone merges with Fabric OS zones containing Fabric Assist mode and QuickLoop
zones are supported when the MP Router is used for the FCI P services, users of the MP
Router are not expected to manage such zones from the Router. It is not possible to manage
such zones from Advanced Web Tools.
FA and QL zones can be managed in the CLI of the MP Router, or in the CLI, Advanced
Web Tools, or supported managem ent applications of Fabric OS-based switches.
Fibre Channel Layer
2 fabric parameter
management
It is not p
ossible to manage the following fabric parameters from Advanced Web Tools:
• RA_TOV
• ED_TOV
• RSCN_Mo
de
These pa
rameters can be managed from the CLI.
NVRAM-related cleanup
XPath 7.3.0b or later explicitly checks for NVRAM corruption that might have occurred
during use of earlier XPath releases. It also provides a utility for cleaning the corruption.
If you do not run the utility, failures might occur due to XPath OS detection of corrupt
NVRAM. The utilit y runs during installation when firmwareDownload is used as the
installation mechanism. If firmwareDownload is used to up grade the recovery kernel
and install XPath OS, there s hould be no impact—NVRAM will be silently cleaned. If other
installation mechanisms are used, or if the new recovery kernel is not installed, then the
NVRAM might remain corrupt, leading to failures, unless you explicitly clean the NVRAM
using the following mechanism. Because XPath 7.3.0b or later is more insistent on good
NVRAM content, these failures will occur more often in these versions than in previous
versions of XP ath OS.
NVRAM cleanup has been integrated into th e latest version of the recovery kernel. If you
use firmwareDownload from the latest xpath_rk package, the recovery kernel will
be updated, any NVRAM corruption will be resolved, and the latest XPath OS will be
installed in a single step.
If you are unable to use firmwareDownload to install the recovery kernel package, follow
the product manual instructions to install the XPath Recover RPG through PMO N. After you
have booted into the recovery kernel, enter the shell by entering shell at the rash prompt.
Runthenvcleanutilityandansweryes when it prompts you. This will rectify any NVRAM
corruption that might exist. Reboot the switch after the cleanup and reset the cfgbank value
to its previous entr y to boot into XPath OS.
