sandisk not recognized windows 10 has at this point recognized the logical board number of the adapter that the configuration manager 500 needs to shut down . The configuration manager 500 makes the NetWare Operating System call LSLGetMLIDControlEntry to search out an entry point into the adapter driver 308. As a half of the system name, the configuration supervisor 500 passes the logical board quantity as a parameter. The LSLGetMLIDControlEntry system name returns a pointer to the DriverControl entry point for the requested board. The DriverControl entry to the HSM supplies a means to quiesce or remove an occasion of the motive force. At a decision state 924, the configuration supervisor 500 determines whether the consumer has requested a driver droop or resume.
Diagnosing intermittent errors could be a frustrating and time-consuming process. For a system to ship consistently high availability, it have to be resilient to these sorts of faults. The completion routine then determines whether the person has requested to suspend or resume an adapter 310 state . If a person requests to restart an adapter 310, the completion routine calls the adapter driver's reinitialize routine . Otherwise, if the person requests to droop an adapter 310, the completion routine calls the motive force's droop routine . After an adapter's re-initialization or suspension , the adapter driver 308 creates another device state IRP .
Traditionally, the adapter driver for a number of the mass storage adapters is the first adapter driver loaded by WinNT, in order that different drivers have entry to a mass storage medium. WinNT then masses the rest of the drivers . Starting in a decision state 900 in FIG. 9A, the configuration manager 500 checks whether the adapter's class is of the kind “LAN” . For PCI methods, each adapter maintains info in its PCI configuration space indicating its class.
An example of such a solution is described in U.S. No. 5,210,855 to Thomas M. Bartol. The method as defined in claim 1, moreover comprising receiving a request for the recent add of the programmable mass storage adapter from a consumer interface program. A NetWare person interface 518 initiates the requests to the configuration supervisor 500 to freeze and restart communications to a specified adapter 310. A distant Simple Network Management Protocol agent 520 can even start the request to freeze and resume communications to the configuration manager 500 by way of an area SNMP agent 522.
9A and 9B illustrate the method by which the configuration supervisor 500 suspends and restarts the communication of a network adapter, such because the adapter 104. The configuration manager 500 maintains details about the configuration area for every of the adapters maintained on the system. However, the configuration manager 500 does not know the logical number that the NetWare Operating System has assigned to each adapter.
Also, defined by the PCI specification, an adapter can have up to six BARs. It is up to the adapter vendor to implement a quantity of BARS within the adapter for I/O or memory addressing, as desired. According to the PCI specification, each of the six BAR entries in an adapter's configuration house is identified as to its useful resource sort (bit zero indicates whether or not this BAR describes a reminiscence area or I/O space).
In a third architectural embodiment of the invention, the I/O platform is plugged in as an option to regulate non-intelligent gadgets as are recognized by expert technologists. 15 is one embodiment of a flowchart displaying the method by which an adapter driver locates and initializes a mass storage adapter beneath the Windows NT Operating System within the sizzling add course of proven in FIG. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top-level block diagram displaying a fault tolerant computer system of 1 embodiment of the present invention, together with a mass storage adapter and a network adapter. The methodology as defined in declare 15, whereby the new mass storage adapter is configured to communicate with a Peripheral Component Interconnect bus.
The HDM is designed to communicate through messages with any kind of working system executing on the pc. These messages correspond to primitives which allow scorching add and hot swap of adapters plugged into the motherboard. A bridge 230 and a bridge 232 connects, respectively, the PC bus 214 with PC bus 234 and the PC bus 216 with the PC bus 236 to supply enlargement slots for peripheral devices or adapters. The adapter devices 238 and 240 are electrically and mechanically connected to the PC buses 234 and 236 by PC slots corresponding to slot 241. Hence, an adapter is “plugged” right into a slot.
Moving to state 714, the configuration supervisor 500 programs the configuration area of the new adapter. Finally, the configuration supervisor 500 resumes operations to the entire adapters situated on the canister . For mass storage adapters 102, the configuration manager 500 notifies the NWPA 510 to resume communications. For community adapters 104, the configuration manager 500 contacts the LSL 502 to resume conmmunications.
Additionally, system users need a process to hot add their legacy adapters, without purchasing new adapters that are specifically designed for hot plug. As system calls for develop, organizations must regularly increase, or scale, their computing infrastructure, adding new processing power, memory, mass storage and network adapters. With demand for 24-hour access to critical, server-based data resources, deliberate system downtime for system service or expansion has become unacceptable. The network adapter 104 usually features a network controller 128.
