HP StorageWorks Multi-protocol Router XPath OS 7.4.1f release notes (5697-0243, January 2010)

DescriptionIssue
Users should never reboot the system from the root account using the reboot
command, or data might be lost. To safely reboot the system, log in as root
and change to admin by entering admin at the root prompt. When you are
at the admin shell, execute the reboot command.
Root reboot command vs. ad-
min user reboot command
A private host attached to a Fabric OS switch might not be able to discover
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 zoning
While zone merges with Fabric OS zones containing Fabric Assist mode and
QuickLoop zones are supported when the MP Router is used for the FCIP
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 management applications of Fabric
OS-based switches.
FA and QuickLoop zone
management
It is not possible to manage the following fabric parameters from Advanced
Web Tools:
• RA_TOV
• ED_TOV
• RSCN_Mode
These parameters can be managed from the CLI.

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 utility runs during installation
when firmwareDownload is used as the installation mechanism. If
firmwareDownload is used to upgrade the recovery kernel and install XPath
OS, there should be no impact—NVRAM will be cleaned silently. 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 XPath OS.
NVRAM cleanup has been integrated into the latest version of the recovery
kernel. If you use firmwareDownload from the latest xpath_rk package,
the recovery kernel is updated, any NVRAM corruption are resolved, and the
latest XPath OS is 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 PMON. After you have booted into the recovery kernel, enter
the shell by entering shell at the rash prompt. Run the nvclean utility and
answer yes at the prompt. This rectifies any NVRAM corruption that might
exist. Reboot the switch after the cleanup and reset the cfgbank value to its
previous entry to boot into XPath OS.
