Emerson Extensions Using HPI-B

After calling saHpiControlStateSet(), a new resource with the domain name you supplied as parameter is created. Additionally, a hot swap event of type ACTIVE for the created resource is sent. The newly created shelf is also added to the HPI multishelf configuration file as a new entry.

All shelves must have different IP addresses.

4.3.5.2Removing Shelves and Domains

In order to dynamically remove a shelf/domain, you must invoke the HPI function saHpiControlStateSet() and provide the following parameters.

Parameter	Value
SessionId	Handle to session context.
ResourceId	Resource ID of the addressed resource.
CtrlNum	Number of the control for which the state is
	being set.
CtrlState	Pointer to control state as described in Table
	"Domain Management Control State" on page 29.
	In this control state, fill the field body as follows:,
	[0]	: 2 (stands for "remove domain")
	[1] - [4] : IP address of shelf you want to add (little
	endian order)
	[5]	- [6] : port of shelf (little endian order)
	[7]	- [n] : Domain name

If the domain/shelf specified in the call exists, the domain/shelf is removed, an HPI domain removed event is generated and any sessions that may be open to this domain are closed. Furthermore the domain shelf resource in the HPI domain is removed and a hot swap even of type "NOT_PRESENT" is generated.
