Embodiment
Some embodiments of the present invention can be described in detail as follows.Yet except describing in detail, the present invention can also be widely implements at other embodiment, and scope of the present invention do not limited, its with after claim be as the criterion.
Prosperity along with science and technology, the user is also more and more higher to the dependence of main frame, therefore in the main frame stored data also phase shape become more and more important, in case when not utilizing keyboard input shutdown command just to press host power switch on the machine as yet to close the operating system of not supporting rank configuration and power management, host power supply will be cut off immediately and influence the program structure of operating system, or cause the damage of the inner stored data of main frame.This abnormal shutdown phenomenon can make company suffer tremendous loss, therefore must utilize the method for safety shutdown of the present invention, makes and does not support the operating system of rank configuration and power management to close safely.
The operating system major part that the Linux of rank configuration and power management is advanced in general support is used on two kinds of main frames, wherein a kind of main frame is that to utilize static disk (flash disk) to come access data, another kind of main frame then be in addition to come the access data with hard disk (hard disk).Though use its operating system of main frame of static disk to there is no the pattern of supporting rank configuration and power management, be stored in the data on the static disk, can't lose or cause the damage of host hardware part because of closing suddenly of host power supply.And when closing the power supply of the main frame that uses hard disk suddenly, data in the hard disk is damaged or the phenomenon of entanglement easily, and make the user when starting shooting again next time, the operating system injury that the action of inspecting and revise this undesired shutdown is caused the data structure of must taking time.If the power supply the when data in hard disk is being read or is depositing on the unexpected Shutdown Hosts, the hard track on a drum or a disk of easier damage causes the loss of data stored in the hard disk, reduces the serviceable life of hard disk.Following embodiment is used in the main frame that uses hard disk with method of the present invention, and the operating system on the main frame do not support the into pattern of rank configuration and power management, does not still limit its scope of invention.
Common one uses the main frame of hard disk, if the operating system of its use is not for supporting the (SuSE) Linux OS of rank configuration and power management, then before host power supply will be closed, must utilize keyboard that next road of operating system is instructed with safety shutdown operating system, just can press host power switch afterwards with the Shutdown Hosts power supply.This instruction is generally " shutdown-h now ".But difference along with enterprise demand, often as the main frame of server (server), equal on-keyboard and display, maintenance or necessary shutdown renewal part if main frame must shut down, must connect keyboard and display more in addition, or be linked on another computing machine with the suitable time-consuming and trouble of the input of carrying out shutdown command.If directly press the power switch on the main frame, though can reduce spent time of shutdown, can influence the serviceable life of hard disk and cause the damage or the loss of the data on the hard disk, therefore must utilize method of the present invention, so that Host Security is closed.
The present invention sets up a driver provided by the present invention at first earlier under operating system, this driver can the call operation system make it automatically perform the normal shutdown program.When the user pressed power switch on the main frame and desires Shutdown Hosts, host power switch can be sent a system management interrupt (system managementinterrupt by chipset; SMI) central processing unit (CPU) of signal to the main frame, central processing unit can be carried out immediately and be positioned at basic input/output (basic input/output system; BIOS) Nei system management interrupt service routine code. after the basic input/output on the main frame received this shut down event, this interrupt service routine code was set up a shutdown flag immediately and is stored in the available internal memory.This shutdown flag is a kind of of signal, and adopts the shutdown flag whether to depress the foundation of power switch as differentiation in the present embodiment, but does not limit its scope of invention.Present embodiment is that the shutdown flag is stored in (the complementary metal oxide semiconductor of a complementary type metal-oxide-semiconductor (MOS) on the host computer system; CMOS) random access memory (random accessmemory; RAM) on, but do not limit its scope of invention.Set up the purpose of a shutdown flag (shutdown flag) at the fixed address place of complementary type metal-oxide-semiconductor (MOS) random access memory, be the message of notifying driver one shut down event provided by the present invention to produce.
Complementary type metal-oxide-semiconductor (MOS) random access memory is normally as the usefulness of basic input/output message access.On complementary type metal-oxide-semiconductor (MOS) random access memory (CMOS RAM) normally with 0 and 1 pattern of representing signal, the deviser can set 0 at a certain fixed address place on the complementary type metal-oxide-semiconductor (MOS) random access memory be a normal flag, and 1 be a shutdown flag, differentiates the kind of signal and do suitable running with convenient driver provided by the present invention.
After driver provided by the present invention hangs up operating system, this driver will be monitored the stored position of shutdown flag on this complementary type metal-oxide-semiconductor (MOS) random access memory constantly, driver of the present invention will go to scan the stored position of shutdown flag on the complementary type metal-oxide-semiconductor (MOS) random access memory p.s. once, but along with user's demand, will prolong or shorten this interval time that scans.In case driver finds that after having set up the shutdown flag on the complementary type metal-oxide-semiconductor (MOS) random access memory, driver call operation system immediately makes it carry out normal shutdown program in proper order, and system is normally closed, the power supply of last Shutdown Hosts.The step of this normal shutdown can prevent the phenomenon that the data structure of operating system is damaged, and also can prevent the phenomenon that hard track on a drum or a disk is damaged.When system started shooting next time, the basic input/output of main frame will internal memory be deleted this shutdown flag automatically made it revert to a normal flag, next just begins to enter operating system to carry out the normal operation of main frame.
With reference to shown in Figure 1, this is the process flow diagram of utilization safety shutdown main frame of the present invention.At first press power switch to open the power supply 10 of main frame, next enter the basic input/output 12 of main frame.Basic input/output begins initialization system management mode (System Management Mode, SMM), and begin system can (enable) by system management interrupt (the System managementInterrupt of central processing unit that chipset is issued to, SMI), and begin to provide system management interrupt service routine (SMI Handler Routine) for central processing unit with 21.Then basic input/output is stored in the shutdown flag 14 that sets on the complementary type metal-oxide-semiconductor (MOS) random access memory before can removing earlier before operating system loads.Next operating system operates simultaneously with basic output/input system.On the one hand if system produces system management interrupt, central processing unit will suspend present work, then carry out the system management interrupt service routine 22 that basic input/output provided, this program will be checked the source of interrupting, and whether press 23 to judge power switch.If the source of interrupting is that power switch is pressed, a fixed position of a complementary type metal-oxide-semiconductor (MOS) random access memory that then can be on host computer system is provided with a shutdown flag 24.If judge that power switch is not pressed, then carry out the service 25 of other system management interrupt signal.Work 26 before central processing unit promptly recovers to interrupt after the EOP (end of program).On the other hand, operating system then begins to load, and loads a driver 16 that is used to detect the shutdown flag provided by the present invention.When operating system and driver load finish after, whether the fixed position that this driver begins to detect constantly complementary type metal-oxide-semiconductor (MOS) random access memory immediately produces a shutdown flag 18.In case driver detects the shutdown flag on the complementary type metal-oxide-semiconductor (MOS) random access memory, then the driver program of the automatic Shutdown Hosts of call operation system immediately just cuts off the electricity supply 20 after the program that operating system is normally closed automatically.
Comprehensively above-mentioned, the invention provides a method, the default normal shutdown program of the operating system of utilization on main frame, detecting host power switch at the driver provided by the present invention on the operating system has been pressed behind the signal of the system management interrupt sent, driver provided by the present invention is that the call operation system makes it automatically perform default normal shutdown program, and the power supply of Shutdown Hosts, with the safety of safety shutdown main frame and attended operation system.But the present invention is the safety of stored data and promote the main frame efficiency of operating in the maintenance host also.The present invention more can prolong the serviceable life of main frame.
The above only is preferred embodiment of the present invention, this embodiment only be used for the explanation but not in order to limit claim of the present invention.Still can be changed in the category that does not break away from flesh and blood of the present invention and implemented, these variations should still belong to scope of the present invention.
