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
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
OpMan.trace
InstallManager.log
<target>\InstallManager.log
discagent.trace
discmanager.trace
InventoryResults.xml
