Support Notes for SUSE Linux Enterprise Server 11 Support Pack 1 for HP Integrity Servers

If the system was working previously, try the pdt command at the EFI prompt to locate
any potential bad memory cells. If there are PDT entries, consider replacing the bad memory.
• Enabling rx7640 or rx8640 servers to power off
The normal behavior on rx7640 and rx8640 servers is for an nPartition to be made inactive
(all cells are in a boot-is-blocked state) when shutdown -h or poweroff is issued from
the SLES command line. This behavior is established with the acpiconfig disable
powerdown setting, which is the normal setting for the single-pci-domain ACPI
configuration.
On HP Integrity Superdome servers, an nPartition is always made inactive when halted
from the operating system (for example, after shutdown -h), and this behavior cannot be
changed.
When softpowerdown is enabled on an rx7640 and rx8640 server, if one nPartition is
defined in the server then halting the operating system powers off the server cabinet
(including all cells and I/O chassis). On an rx7640 and rx8640 server with multiple nPartitions,
halting the operating system from an nPartition with softpowerdown enabled causes only
the resources on the local nPartition to be powered off.
You can run the acpiconfig command with no arguments to check the current setting and
the softpowerdown setting; however, softpowerdown information is displayed only
when different from normal behavior.
If you want an rx7640 and rx8640 server to power off when using either the shutdown -h
or poweroff command, run the acpiconfig enable softpowerdown command from
the EFI shell, and then reset the nPartition to ensure the new ACPI configuration takes effect.
To power on hardware that has been powered off, use the PE command from the management
processor command menu. To make an inactive nPartition active, use the management
processor BO command to boot the nPartition past the boot-is-blocked state.
