Embodiment
The embodiment of the invention provides a kind of method of knowing that disk is pulled out, comprising: the information that obtains expression disk frame fault; Judge on the loop of described disk frame and whether have disk on the throne; When having at least one disk on the throne on the loop of described disk frame, the input port of at least one disk on the throne on the loop of this disk frame of bypass, when the bypass time of presetting arrives, the input port of at least one disk on the throne is inserted the loop of disk frame, make at least one disk on the throne send loop initialization protocol frame; When not having disk on the throne on the loop of described disk frame, disconnect the loop of described disk frame, and when the bypass time of presetting arrived, closed described loop was so that main frame sends the loop initialization protocol frame; The loop initialization protocol frame is used to trigger loop initialization so that main frame is known has disk to be pulled out.
Wherein, the information of expression disk frame fault can be: the bypass detection signal of the disk failure on the expression disk frame or the expression link that is in incorrect state normal indicator signal whether.Above-mentioned disk frame is meant disk frame one in following embodiment one to embodiment three, be meant disk frame two in embodiment four.
Consult Fig. 1 to Fig. 3, a kind of method of knowing that disk is pulled out the when embodiment of the invention one is introduced a kind of main frame and is connected with disk frame one, this method comprises:
The logic detection module of step 101, disk frame one detects the bypass detection signal, judges the height of the level of bypass detection signal, when the bypass detection signal is low level, determines that the disk corresponding with this bypass detection signal is pulled out.
When the disk on the disk frame one 1 was pulled out, the logic detection module detected the bypass detection signal and becomes low level.
Disk 1 has two port port A and port B, and each port has input port (Inbound) and output port (Outbound).Port A and port B can insert the loop of different disk frame, and corresponding, the FC connector of disk provides two bypass detection signals :-EN bypass port A and-EN bypassport B.Suppose that this disk is connected with this disk frame by port A, when disk 1 quilt dial-out, the logic detection module detects-and EN bypass port A becomes low level, and wherein ,-EN bypass port A becomes low level and represents this disk failure.
After step 102, logic detection module detect low level bypass detection signal, (Port-Bybass Circuit PBC) sends by-passing signal, the input port and the output port of this disk 1 of control PBC circuit bypass to the port bypass circuit, to guarantee the unobstructed of loop, as shown in Figure 2.
The input port of above-mentioned this disk of control PBC circuit bypass and the specific implementation of output port are: the output enable of control PBC disconnects with the input port of this disk and being connected, and the input of control PBC enables to be connected with the output port disconnection of this disk.
Step 103, when on definite disk frame one, also having a disk on the throne at least, the logic detection module sends by-passing signal to the PBC circuit, the input port and the output port of the disk on the throne on the control PBC circuit bypass loop, i.e. the input port and the output port of disk 2,3, as shown in Figure 3.
Logic detection module controls PBC circuit will be inserted loop by the disk on the throne of bypass when arriving step 104, the bypass time of presetting, and disk on the throne sends the LIP frame to trigger loop initialization, and loop has entered init state.
Because of the input port of disk on the throne by bypass, make the input port lossing signal of disk on the throne, when input port lossing signal time of disk on the throne greater than maximum time of reception (The Receiver Transmittertimeout value, R_T_TOV) time, disk on the throne carries out self check, whether for example detect internal clocking normal, after self check is passed through, disk requests on the throne enters the INITIALIZATION state, under this state, transmit messages the LIP frame of accusing port error (LIP (and F8, F7) or LIP (F8, AL_PS)).
When the logic detection module arrived in the bypass time of presetting, control PBC circuit will be inserted loop by the disk on the throne of bypass, as shown in Figure 2, control PBC circuit will be by the mode of the disk access loop on the throne of bypass: the output enable of control PBC is connected with the input port of this disk, and the input of control PBC enables to be connected with the output port of this disk.The bypass time of wherein, presetting can be 150ms.After disk on the throne is access in loop, this disk on the throne is received the LIP frame of report port error by loop, then by at least 12 normal LIP frame (LIP (F7 of loop transmission, F7) or LIP (F7, AL_PS)), like this from the report port error the LIP frame to normal LIP frame, loop has just entered init state, has begun loop initialization.
Step 105, send the LIP frame to trigger loop initialization, after loop has entered init state, select MASTER, send Frame by MASTER and carry out loop initialization, know that this disk 1 is pulled out at the disk on the throne of step 104.
Wherein, the mode of selecting MASTER can be select global unique name on the loop (World WideName, WWN) value minimum as MASTER, also other selection modes can be arranged, do not influence realization of the present invention.
The Frame that MASTER sends can comprise: send the initial framework of loop and distribute frame (LoopInitialization Fabric Assigned, LIFA), LIPA (Loop Initialization PreviouslyAssigned), loop initialization distributes frame (Loop Initialization Hard Assigned firmly, LIHA), the soft distribution frame of loop initialization (Loop Initialization Soft Assigned, LISA) frame, LIRP (LoopInitialization Report Position), and LILP (Loop Initialization Loop Position) frame, Frame is sent by MASTER, be used to obtain the address information of disk on the throne, and get back to MASTER by loop, main frame by host bus adaptor (Host Bus Adapter, HBA) card is connected with the PBC circuit, received Frame as a node on the loop, known the topological structure of loop, i.e. the address information of disk on the throne on the loop, thereby can know that this disk 1 is pulled out.
Wherein, PBC circuit all disks on the throne on can bypass disk frame one are all sent the LIP frame by all disks on the throne of bypass in the step 104 in the step 103, trigger loop initialization, have strengthened the reliability that triggers loop initialization.
