It includes an adapter box to securely house the system's power adapter. Starting at state 1400, the configuration supervisor 1100 reads the seller and adapter ID of the adapter 310 that has been hotly added. The vendor and adapter ID are usually maintained in Read Only Memory on an adapter 310. Novell has provided a set of support modules that creates the interface to the LSL 502.
For instance, if the class of the adapter 310 had been of type “SCSI” , the configuration manager 500 would comply with the method described in FIG. 10 for freezing the communication for a mass storage adapter 102. Next, in some embodiments, the recent plug hardware 318 asserts bus reset, if needed, earlier than eradicating power . In other embodiments, the configuration supervisor 500 specifically causes bus reset to be asserted earlier than directing the hot plug hardware 318 to take away energy. For embodiments of the computer shown in FIG.
Maxlan-boards is a variable maintained by the NetWare Operating System indicating the utmost number of logical network adapters supported. A significant component of cost is hiring administration personnel. These prices decline dramatically when pc methods can be managed utilizing a standard set of instruments, and where they don't require immediate consideration when a failure occurs.
You can now talk to your partners on the headphone while enjoying a multi-channel community video games. All of these are carried out on one computer. Mount your system on a wall or underneath a desk.
If the request is a droop request, the configuration manager 500 proceeds to state 1008 (FIG. 10B). If the request is a restart, the configuration supervisor 500 proceeds to state 1030 (FIG. 10C). 10A describes the Filter CDM 513 initialization course of. Starting in state 1000, the NetWare Operating System begins the execution of Filter CDM 513. The Filter CDM 513 obtains the physical PCI location of each adapter . The Filter CDM obtains this information by making a Novell NetWare Operating System name named HAM_Return_Bus_Info.
At state 1004, the Filter CDM 513 registers the mass storage adapter 102 with the configuration supervisor 500. The Filter CDM 513 additionally registers to receive “Adapter Attention” events, to get notification from the NetWare Operating System when an adapter 310 fails. Finally, in state 1006, the Filter CDM 513 waits for requests to droop and restart the I/O from the configuration manager 500.
For each such BAR, the LSL 502 configuration spaces are looked for an I/O port address which matches this BAR. This process continues until a match is discovered, figuring out the LSL 502 configuration house which describes this adapter. If no match is discovered, then LSL 502 has no logical board describing this adapter, and no driver exists to service this board. Before beginning in state 800, an event has occurred, such as a failure of an adapter, and the operator has been knowledgeable of the failure.
The scorching plug system driver 306 stops and resumes the communications between the adapter 310 and the adapter driver 308. During a hot add or swap of the adapter 310, the hot plug hardware 312 deactivates the facility to the PC slots 241 and 266 (FIGS. 2 and 3). One embodiment of the recent plug hardware 312 may include the network of microcontrollers 225 (FIGS. 2 and 3) to hold out this performance. The software program structure helps the recent add and swap of off-the-shelf adapters, including these adapters which are programmable. A related expertise, to not be confused with hot plug systems, is Plug and Play outlined by Microsoft and PC product vendors. server spare parts and Play is an architecture that facilitates the integration of PC hardware adapters to techniques.
For some embodiments, the hot plug hardware 312 additionally removes bus reset, if needed, after applying power . In other embodiments, the configuration manager 500 should specifically de-assert the bus reset. For the embodiment of the pc proven by FIG. 2, the configuration manager 500 reprograms the configuration house of the changed adapter to the identical configuration because the old adapter . For the embodiment of the pc proven in FIG. three, the configuration manager 500 reprograms the configuration space and resumes the communication of each adapter located on the canister on which the adapter was swapped .
9A and 9B are flowcharts exhibiting one process by which the configuration supervisor might droop and restart I/O for warm swapping community adapters under the NetWare Operating System, shown in FIG. 2 is a block diagram exhibiting a first embodiment of a multiple bus configuration connecting I/O adapters and a community of microcontrollers to the clustered CPUs of the fault tolerant computer system, shown in FIG. The area of the invention pertains to I/O adapters in laptop systems. More particularly, the field of invention pertains to the recent add and swap of adapters on a computer system. The configuration manager 1100 controls the communication between every adapter and adapter driver by calling the SCSI port 1104 and NDIS 1105.
