Redundant ROM Image Recovery
If power is interrupted during the flash process, a server with redundant ROM boots
as usual, but the inactive (redundant) ROM image is corrupted.
A Power-On Self-Test (POST) error message is displayed:
105 – Current System ROM is corrupt – now booting redundant
System ROM
In this instance, you are required to flash again for the invalid image to become valid.
After you flash the invalid image, the system then powers up using the most recently
flashed image.
Automatic Server Recovery-2
You can enable the Automatic Server Recovery-2 (ASR-2) feature to restart a server
after a critical hardware or software error occurs. If a critical error occurs, the server
records the error information in the IML, and then restarts the system. Depending on
your server setup utility, you can configure the system for either automatic recovery
or for attended local or remote access to diagnostic and configuration tools.
NOTE:
ASR-2 is available only on operating systems using the ASR-2 drivers provided by
HP.
ASR-2 depends on the ASR-2 timer and the Health Driver to routinely notify the
ASR-2 hardware of proper system operations. If the time between ASR-2
notifications exceeds the specified period, ASR-2 assumes a fault has occurred and
initiates the recovery process.
To configure ASR-2:
•
On servers running the ROM-Based Setup Utility (RBSU):
a.
Run RBSU.
b.
Select the
Automatic Server Recovery
menu.
c.
Set the ASR Status to Enabled.
d.
Set the ASR Timeout.
