Issue Description Root reboot command vs. admin user reboot command 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. FA zoning 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 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 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. Fibre Channel Layer 2 fabric parameter 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. 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 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.
