Array controller ROMs Array controllers support Recovery ROM, which is a redundancy feature that ensures continuous system availability by providing a backup ROM. During the flash process, a new version of the firmware can be flashed to the ROM while the controller maintains the last known version of the firmware. If the firmware becomes corrupt, the controller reverts back to the redundant version of the firmware and continues operating. NOTE: Storage option ROMs cannot be downgraded with ROMPaq because ROMPaqs have been retired as a delivery method for storage options. Lights-Out management ROMs To perform disaster recovery for RILOE II, iLO, iLO 2, iLO 3, and iLO 4, see the documentation for your particular Lights-Out management product on the Remote Management website at http:// www.hp.com/servers/lights-out. Recovering from an installation failure Collecting trace directories HP SUM generates a set of debug trace logs located in the %TEMP%\hp_sum directory on Windows systems and \tmp\hp_sum on Linux systems. These files contain internal process and debug information, which can be useful in determining HP SUM failures. HP SUM also has a log collecting utility for Windows (GatherLogs.exe) and Linux (GatherLogs.sh) that creates a compressed file (a Windows .zip file or a Linux tar.Z file) with all the logs. Run this utility to gather all the logs in one file. NOTE: To break out to a Linux console while booted to the Smart Update Firmware DVD or SPP, press Ctrl+Alt+d+b+x. Each key (d, b, and x) is hit in succession. This command allows you to collect logs from the \tmp\hp_sum directory. Examine the OpMan.trace, and the InstallManager.log trace files to determine the cause of the failure. These files provide the following information. Trace files Function OpMan.trace Provides operations trace of the overall installation process. InstallManager.log Provides the interaction between the Operations Manager and the remote installation client. Any failure in network communications is reported in this file and surfaced as an Installation Failed message for the affected component and potentially all components that follow the failing component. \InstallManager.log Provides the interaction between the Operations Manager and the remote installation client. Any failure in network communications is reported in this file and surfaced as an Installation Failed message for the affected component and potentially all components that follow the failing component. discagent.trace Provides the details of the execution of the discovery agent on either the local system during a local installation or the remote target server. If a discovery tool fails, it is reported to this trace file and surfaced as a Discovery Failed message. discmanager.trace Provides the interaction between the Operations Manager and the remote discovery client. If a discovery tool fails, it is reported to this trace file and surfaced as a Discovery Failed message. InventoryResults.xml Provides details of the component inventory from the repositories. Settings.xml Provides general settings information of HP SUM such as Force downgrade or upgrade. 28 Troubleshooting
