Hi,
OpenHPI has a few additional APIs to manage the OpenHPI specific configuration
dynamically.
In openhpid/oHpi.c you find the handler operation APIs which manage plugin
instances:
oHpiHandlerCreate
oHpiHandlerDestroy
oHpiHandlerInfo
oHpiHandlerGetNext
oHpiHandlerFind
oHpiHandlerRetry
and other functions to address OpenHPI configuration.
The description there is pretty short, but should tell you what they do.
You can find coding examples in the clients (clients/ohhandler.c) and you can
use these client programs also in your testbed.
There are man entries as well.
That way you should be able to reconnect to a shelf manager or change the
connection method.
Only the conf files are not changed by these programs. The changes will be not
persistent.
Cheers,
Uli

Subject: Re: [Openhpi-devel] [openhpid] How to connect to Shelf manager without
restart openhpi daemon
Thank you for your reply, Mohan.
I also think as yours.
But digging into openhpi source code, I found a function which establishes
connection to shelf manager, that is ipmi_lan_setup_con().
This function is one of the device driver functions that allows upper
application to talk to IPMI hardware platform. It takes
configuration parameters and make a connection to IPMI hardware platform.
But I wonder if we provide configuration parameter changes and invoke it, the
daemon still works or not? Is it the function that
meets our purpose?
Thanks,
hung
