Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a storage management method for linking a storage device with system management software.

[0002]

2. Description of the Related Art In a management system connected to a network, system management software is used to manage devices connected to each other on the network. The system management software automatically detects devices connected to the network. In addition, the system management software uses SNMP (Si
mple Network Management Protocol) traps (messages sent to the management system when an event occurs on a device) to recognize changes in the status of devices connected to the network, and to change the color of the icon indicating the device, etc. The status of the device is visually displayed to the user. When the system management software manages a device connected to a network, trap information (trap information) transmitted from the device to the management system needs to be registered in the system management software. The trap information includes a trap identifier, a detailed description of the trap, and a status level (normal, degraded, warning, etc.).

[0003] The system management software that receives the trap, for example, based on the registered trap information, for example,
The status of the device is visually displayed by displaying a unique color indicating the status of the device.

[0004] UDP (User Datagram Protocol) used for trap transmission in a lower protocol of SNMP is a connectionless type protocol. In this protocol, there is no guarantee that the transmitted trap always reaches the destination, and no function such as error or retransmission control is provided. The technology related to the system management software
P / IP and OSI Network Management "(by Hisao Ohgane, Soft Research Center, Inc., ISBN4-915778-21-5).

[0005]

According to the prior art, when a trap whose trap information is not registered in the system management software is transmitted from a device to be managed, the system management software executes the transmitted trap. Cannot recognize the state change of the device corresponding to. For example,
If trap information indicating device failure is registered but trap information indicating recovery from the failure is not registered, the system management software can recognize the occurrence of the device failure, but cannot recover from the device failure. I can't recognize.

Further, when a trap transmitted from a device is lost due to a network failure or the like, there is a problem that system management software cannot recognize a change in the state of the device.

An object of the present invention is to provide a system management apparatus capable of recognizing a trap that is not registered in the system management software even when the trap is transmitted from a device, particularly a storage device (hereinafter referred to as a "storage device"). It is to provide.

[0008]

In order to achieve the object of the present invention, there is provided a storage cooperation management program for linking system management software with a device to be managed. First, a trap is defined for a state change that the managed storage device wants to manage, but the corresponding trap is not supported. Next, the trap is registered in a trap definition table of the system management software.

[0009] The storage cooperation management program executes the SNMP
When the status of the storage device to be managed is acquired from the MIB information and the above status change is detected, a corresponding trap is issued. The system management software can recognize the corresponding state change from the trap. For example, if a failure trap for a site is supported, but a recovery trap from that failure is not supported,
Register the recovery trap from the failure in the system management software. The storage linkage management program uses the MIB
(Management Information Base: various information related to the device) The recovery of the above-mentioned part is detected from the information, and the above-mentioned recovery trap is issued. Thereby, the system management software can recognize the corresponding state change by referring to the trap definition registered above. At this time, there is no need to support the trap in the device, which is required in the related art. If the storage device has a function to return the status by SCSI command, the Fibr supported by the storage device
The status can be obtained via an interface such as e Channel or SCSI (Small Computer System Interface). For example,
When the storage device returns the device status using the SCSI Mode Sense command, the storage linkage management program
By acquiring the status of the storage device by the se command, a status change is detected and a corresponding trap is issued. Thereby, the system management software can recognize the corresponding state change by the issued trap.

In order to cope with the case where the trap is lost due to a failure on the network or the like, the storage cooperation management program detects a change in the state of the storage device to be managed from the MIB information or the SCSI command. The storage cooperation management program issues a corresponding trap even if the storage device is in a state change that supports the trap. Thereby, even if the trap from the storage device disappears, the system management software can recognize the corresponding state change by the trap from the storage cooperation management program.

When the status of the storage device 4 changes, a trap identifier corresponding to the status change is sent from the storage cooperation management program 11 to the system management software 16 as a trap. The system management software 16 recognizes the received trap as a trap from the target device and performs a process corresponding to the trap identifier.

The management object detection process 12 is a program for performing a process of detecting the storage device 4 to be managed.

FIG. 8 is a flowchart showing the procedure of the management object detection processing 12. This processing is performed arbitrarily. The program of the management target detection processing 12 detects a device managed by the system management software 16 (81). If a device is detected, management target detection processing 1
The second program performs MIB information acquisition processing for acquiring the MIB information 21 of the detected device (82).

If no devices have been detected, or if all devices have been detected, management object detection processing 12
Program ends. The program of the management target detection process 12 determines whether the detected device is the storage device 4 to be managed based on the acquired MIB information 21. The identification of the storage device 4 is performed, for example, by the system detail MIB 37 of the MIB information 21. If the storage device 4 is not a management target, the process returns to the device detection processing 81 (83).

When the storage device 4 is a management target, the program of the management target detection processing 12 performs a state management table registration processing.

Start

FIG. 9 is a flowchart showing the procedure of the state management process 13. The state management processing 13 periodically
This is executed by the storage cooperation management program 11. The storage cooperation management program 11 performs a management target search process. In the management target search process, the storage device 4 registered in the management target detection process 12 is detected. If no registered storage devices 4 have been detected, or if all have been detected, the storage cooperation management program 11 ends the status management process 13 (91).

When the registered storage device 4 is detected, the storage cooperation management program 11 proceeds to a storage status acquisition process. The storage status acquisition process is a process of acquiring the MIB information 21 of the storage device 4 detected in the management target inspection process (92). The storage cooperation management program 11 performs a state comparison process. In the state comparison processing, the state acquired in the storage state acquisition processing is compared with the state stored in the storage state management table 14. If the respective states match, the storage cooperation management program 11 returns to the management target search processing 91. If the statuses do not match, the storage cooperation management program 11 proceeds to the status change process (9
3). The storage cooperation management program 11 performs a status change process. The contents of the state change process will be described with reference to FIG. 10 (94). Then, the storage cooperation management program 1
1 performs a state saving process. The status saving process is a process of storing the status obtained by the storage status obtaining process in the storage status management table 14. The processing content of the state saving processing is the same as that of the MIB information storage processing (95).

FIG. 10 is a flowchart showing the procedure of the state change process 94. The storage cooperation management program 11 performs a corresponding trap search process. In the corresponding trap search process, the status stored in the storage status management table 14 is different from the status acquired in the storage status acquisition process 92, that is, the status has changed, and there is a trap corresponding to the change. This is a process of searching the status change trap table 15 to determine whether to perform
1).

When a trap corresponding to the state change trap table 15 is defined, the storage cooperation management program 11 performs a trap issuing process. The trap issuing process will be described with reference to FIG. 11 (102).

When the trap corresponding to the status change trap table 15 is not defined, the storage cooperation management program 11 performs a storage device management software activation process. In the storage device management software activation process, the storage device management software 18 is activated. At this time, the network address of the storage device 4 is passed to the storage device management software 18 to indicate the target storage device 4 to the storage device management software (103). After the storage device management software activation process, the storage cooperation management program 11 ends the status change process 94.

FIG. 11 is a flowchart showing the procedure of the trap issuing process 102. The storage cooperation management program 11 issues a device unsupported trap 23 defined in the state change trap table 15 for each state change detected in the corresponding trap search processing.

In the power recovery transition determination, the power status is determined (111). If the power status 62 is a failure and the power status acquired in the storage status acquisition process 92 is normal, a power recovery trap issuance process is performed. In the power recovery trap issuing process, the power recovery trap identifier 53 recorded in the power recovery 71 is issued as a trap (1).
12).

Thereafter, a battery recovery transition determination is made (113). If the battery status 63 is a failure and the battery status acquired in the storage status acquisition process 92 is normal, a battery recovery trap issuance process is performed. In the battery recovery trap issuance processing 114, the battery recovery 7
The battery recovery trap identifier 54 recorded in No. 2 is issued as a trap (114).

Thereafter, a fan recovery transition determination is made (115). If the fan status 64 is a failure and the fan status acquired in the storage status acquisition process 92 is normal, a fan recovery trap issuance process is performed. In the fan recovery trap issuing process, the fan recovery trap identifier 55 recorded in the fan recovery 73 is issued as a trap (116).

Thereafter, a cache recovery transition determination is made (117). If the cache status 65 is a failure and the cache status acquired in the storage status acquisition process 92 is normal, a cache recovery trap issuance process is performed. In the cache recovery trap issuance process, the cache recovery trap identifier 5 recorded in the cache recovery 74
6 is issued as a trap (117).

Thereafter, drive recovery transition determination is performed (119). If the drive status 66 is a failure and the drive status acquired in the storage status acquisition process 92 is normal, a drive recovery trap issuance process is performed. In the drive recovery trap issuing process, the drive recovery trap identifier 57 recorded in the drive recovery 75 is issued as a trap (120).

Thereafter, the preventive maintenance warning recovery transition judgment is made (121). If the preventive maintenance warning state 67 is a failure and the preventive maintenance warning state acquired in the storage state acquisition processing 92 is normal, the preventive maintenance warning recovery trap Issue processing is performed. In the preventive maintenance warning recovery trap issuing process, the preventive maintenance warning recovery trap identifier 58 recorded in the preventive maintenance warning recovery 76 is issued as a trap (122).

After issuing the trap, the system management software 16 recognizes the device unsupported trap 23 issued from the storage cooperation management program 11 as a trap from the target device, and performs a corresponding process.

According to the present embodiment, a trap is defined for a state change that the management target apparatus wants to manage but the corresponding trap is not supported, and the trap is registered in the system management software 16. In addition, the storage cooperation management program 11 reads the MIB information 2
