- FIG. 7 is an explanatory diagram representing the execution service management table 1140 shown in FIG. 6 in time series based on the information provision interval 1143.
- the service ID 1140 is specified by the service ID 1140, the device ID 1146, the object type 1147, and the object ID 1148 at the timing of the information provision interval (for example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes). It indicates whether or not each object information needs to be acquired.
- “ ⁇ ” at the timing of each information provision interval indicates that it is necessary to acquire object information corresponding to the “ ⁇ ” at that timing.
- the management computer 1000 may acquire information related to the object ID 1148 of any one of the services. . This is because the same object information in each of the different service IDs 1141 is the same information at the same information provision interval timing. For example, in the case of FIG. 7, at the information provision interval timing “10 minutes”, information related to the object ID 1148 “PortA” included in the service ID 1141 “1” and object ID 1148 “PortA” included in the service ID 1141 “3” Such information is the same information. Therefore, the management computer 1000 may acquire information related to the service ID 1141 “1” or “3”, the object ID 1148 “Port A”. That is, the management computer 1000 only has to issue one information acquisition request for the object ID 1148 “PortA” to the storage device with the device ID 1146 “Stg1” at the timing “10 minutes” of the information provision interval.
- the management computer 1000 When acquiring object information corresponding to the same device ID 1146 and the same object type 1147 included in services of different service IDs 1141 at the same information provision interval timing, the management computer 1000 acquires the information collectively. do it. For example, in the case of FIG. 7, at the information provision interval timing “10 minutes”, the object IDs 1148 “Vol1” and “Vol2” included in the service ID 1141 “1” and the object ID 1148 “Vol3” included in the service ID 1141 “3”. Are the same device ID 1146 “Stg1” and the same object type 1147 “volume”.
- the management computer 1000 makes an acquisition request for information related to the object IDs 1148 “Vol1”, “Vol2”, and “Vol3” to the storage device with the device ID 1146 “Stg1” at the timing “10 minutes” of the information provision interval. You only need to issue one. In this way, an acquisition request in which a plurality of object information acquisition requests are collected may be referred to as a “bulk acquisition request”.

- the value of the timing 1151 is set such that the least common multiple of the information providing intervals 1143 of all the services being executed (or a predetermined group) is one cycle, and the information providing intervals 1143 of the respective services being executed within the cycle It may be the timing.
- the timing 1151 is the information providing interval 1143 “10 minutes”, “15 minutes”, “30 minutes” that is the least common multiple of “5 minutes” as one period, and is being executed within that period. It may be any one of “5 minutes”, “10 minutes”, “15 minutes”, “20 minutes”, “25 minutes”, and “30 minutes”, which is the timing of each information provision interval of each service. (See also FIG. 7).

- the device type 1153, the device ID 1154, the object type 1155, and the object ID 1156 are as described in FIG.
- the related service ID 1157 is an identifier of a service that needs to be acquired related to the object having the object ID 1156 at the timing 1151.
- the management computer ID 1152 “1” issues one object information acquisition request for the object ID 1156 “Port A” to the device ID 1154 “Stg1”.
- the information related to the object ID 1156 “Port A” is required for the related service IDs 1157 “1” and “3”, but since it is the same information, the management computer ID 1152 “1” is acquired at the timing “30 minutes”. Only one request needs to be issued.
- the management computer ID 1152 “3” makes one bulk acquisition request for object information related to the object IDs 1156 “Pool 10” and “Pool 11” with respect to the device ID 1154 “Stg1”. Issue. This is because they have the same device ID “Stg1” and the same object type 1155 “pool”.
- one management computer (referred to as “representative management computer”) among the plurality of management computers 1000 in the computer system 1 may issue only one acquisition request at a certain timing.
- the management computer in charge of acquisition of each object information may be determined (sorted) so that it is good and / or one management computer only needs to issue one bulk acquisition request.

Good.
- This process is an example of a case where a new service is executed and added, but the same applies to a case where an object associated with a service being executed is updated.
- Step 101 When the service detection program 1160 detects a change in service execution status (such as new addition / change of a service), the service detection program 1160 proceeds to Step 102.

- the management computer determination program 1180 refers to the information in the management table 1150, and identifies the service and object information that each management computer 1000 is in charge of, and the information acquisition timing 1151. Then, the process proceeds to Step 104.
- Step 104 The management computer determination program 1180 calculates the least common multiple of the timing 1157 of each service and sets it as an acquisition cycle. Then, the process proceeds to Step 105. For example, the management computer determination program 1180 calculates the least common multiple in the information provision interval of the new service to be executed and the information provision interval 1143 in all (or in a predetermined group) of the execution service management table 1140. For example, in the case of FIG.

新規のサービスを稼働する場合、当該新規のサービスが管理対象とする各新規オブジェクトについて、稼働中の各サービスの各オブジェクトの中に、前記第1のポリシ又は前記第2のポリシに適合するオブジェクトが存在するか否かを判定し、
その新規オブジェクトが、前記第1のポリシに適合すると判定した場合、第1のポリシに適合するオブジェクトを担当中の管理計算機を、その新規オブジェクト情報の収集の担当に決定し、
その新規オブジェクトが、前記第1のポリシに適合せず、前記第2のポリシに適合すると判定した場合、第2のポリシに適合するオブジェクトを担当中の管理計算機を、その新規オブジェクト情報の収集の担当に決定する
請求項5に記載の計算機システム。 - 前記代表管理計算機は、
各管理計算機が担当中のオブジェクトの数を管理し、
その新規オブジェクトが、前記第1のポリシ及び前記第2のポリシの何れにも適合しないと判定した場合、担当中のオブジェクトの数が最も少ない管理計算機を、その新規オブジェクト情報の収集の担当に決定する
請求項7に記載の計算機システム。 - 前記代表管理計算機は、
担当中のオブジェクトの数が所定の閾値よりも多い管理計算機について、その管理計算機が担当中の1つ以上のオブジェクトの担当を、担当中のオブジェクトの数が所定の閾値よりも少ない管理計算機に変更する
請求項5に記載の計算機システム。 - 前記情報収集ポリシには、複数の異なるサービスの中に、情報提供の周期の繰り返しの中で一致するタイミングを有し、且つ、同一の種類のオブジェクトが含まれており、さらに、これらの同一の種類のオブジェクトが1つの装置に含まれている場合、これら同一の種類のオブジェクト情報の収集を1つの管理計算機に担当させる旨のポリシが定義されている
請求項1に記載の計算機システム。 - 前記ポリシに基づいて決定され、前記通知を受領した管理計算機は、情報提供の周期の繰り返しの中で一致するタイミングにおいて、前記1つの装置に対して、前記同一の種類の複数のオブジェクト情報の要求を1つ発行する
請求項10に記載の計算機システム。 - 装置を管理する方法であって、
装置が、管理計算機から管理対象とされる1つ以上のオブジェクトを有しており、
複数の管理計算機が、1つ以上のオブジェクトを管理対象とするサービスを提供しており、
各サービスの各オブジェクトには、情報提供の周期が設定されており、
複数の管理計算機のうちの1つである代表管理計算機が、
オブジェクト情報の収集に関するポリシが定義されている情報収集ポリシと、実行中の各サービスの各オブジェクトに設定されている情報提供の周期と、に基づいて、各オブジェクト情報の収集を担当する管理計算機を決定し、
その決定した各管理計算機に対して、その管理計算機が担当するオブジェクトを通知する
装置の管理方法。
