ACPI Support on HP ProLiant DL380 Generation 5 (G5)

I need ACPI support on HP ProLiant DL380 Generation 5 (G5) but I find that it is partially supported.

Server Information


Server : HP ProLiant DL380 Generation 5 (G5)

OS : RedHat Enterprise Linux 5

Kernel : 2.6.18-8.el5


Requirements

1. Support for S3 sleep state

If we see the content of /sys/power/state on this server, then it shows only “disk” option implying the support of S4 sleep state. The other possible value is “mem” for S3 sleep state. If we execute “echo -n mem > /sys/power/state” to suspend to memory then we get an error “write error: No such device”.



2. Support for CPU power management

The content of /proc/acpi/processor/CPU0/info on this server has the following content

processor id: 0

acpi id: 0

bus mastering control: no

power management: no

throttling control: no

limit interface: no

Quick response shall be highly helpful.

Thanks and Regards,
Adityakar Jha

What are your Power Regulator for ProLiant setting in the iLO?

- Dynamic Power?
- Static High Power?
- Static Low Power?
- OS Control?

Hi David,

Thanks for the reply. If you could tell me how to see the current iLO settings of HP Power Regulator and also how to change the settings.
Is there any command line tool to do the same since the server is on WAN and GUI wont be of much help.

Hi,

The value of HP Power Regulator is set to "OS control" in BIOS.

Were you able to resolve this issue? ACPI BIOS?
