And an installation area 1021. The installation procedure 103 and the configuration information 104
02 in the procedure storage area 1022.

In the node 101, the service processor 1012 receives a system activation request via the communication mechanism 1013. The service processor 1012 accepts, as system activation requests, an installation mode activation request and a normal activation mode.

When the service processor 1012 receives the activation request for the installation mode, the service processor 1012
014 is downloaded to the main memory 1016, and the main processor 1011 is activated.

The boot code 1014 is a program that runs on the main processor 1011 and has the minimum necessary functions. The boot code 1014 corresponds to the input / output unit 10.
15, the system boot data 107 stored in the installation master medium 105 is expanded in the main memory 1016. In addition, if necessary, via the communication mechanism 1013, via the communication medium,

16 on.

The boot code 1014 then passes the execution to the kernel code stored in the OS area 10161, and the system having the installation limitation function is
It starts on the main processor 1011.

In FIG. 1, the nodes 201, 211, 301, 311, 321 and 331 have the same node configuration as the node 101 described with reference to FIG. In the example shown in FIG.
1 node 301, 311, cluster 32 node 32
Reference numerals 1 and 331 each include a disk device as a peripheral device, but do not include an installation master medium.

The cluster 2 includes a node 201 and a node 2
02. The node 201 includes a disk 202 and the installation master medium 20 as peripheral devices.
5 is connected. The node 202 includes a disk 212 and the installation master medium 21 as peripheral devices.
5 is connected.

The contents stored in the installation master medium 205 and the installation master medium 206 are the same as those in the installation master medium 105. Therefore, the system boot data 206, the system boot data 207, and the system boot data 106
Are the same, and the installation package 207
The installation package 217 and the installation package 107 have the same contents. The installation master medium is preferably a portable recording medium, such as a magnetic tape or a CD-ROM, and is a medium that can be easily copied. The installation master medium generally has a large amount of data stored in the medium, and transmitting this data via a communication line may cause a decrease in system throughput. If possible, it is preferable to have it as a local device in its own node.

The node 101 of the master node 1 and the nodes 201 and 211 of the cluster 2
Connected by

The cluster 31 includes a node 301 and a node 312. The node 301 has a disk 302 connected as a peripheral device, and a node 312.
Is connected to a disk 312 as a peripheral device.

21 and the node 331 are connected by the communication medium 6.

As the peripheral devices connected to the nodes, the terminal nodes 301, 311, 321 and 331 do not have an installation master medium.
In this way, the terminal node having no installation master medium accesses the parent node's installation master medium. The parent node is a node that instructs its own node to start.

The parent node of the nodes 301 and 311 is the node 201, and the parent node of the nodes 321 and 331 is the node 211.

The definition of the child node is the reverse of the definition of the parent node. For example, the child nodes of the node 101 of the master node 1 are the nodes 201 and 202 and the node 2

FIGS. 3 and 4 are flowcharts for explaining the operation of one embodiment of the present invention. The operation of one embodiment of the present invention will be described with reference to FIGS.

First, the installation system starts on the node in accordance with the system start request in the installation mode. The system start request is issued from the parent node to the child node via the communication medium (communication medium 4, 5, or 6 in FIG. 1) and the physical interface such as a switch of the parent node itself. Thus, any of the methods directly instructed by the user can be used. In either method, finally, the system startup data of the installation master medium is loaded on the main memory (1016 in FIG. 2) of the node, and the data is loaded on the main processor (1011 in FIG. 2). The function-limited system starts.

Next, the node determines whether or not itself is the master node (step A1 in FIG. 3). Whether or not the own node is the master node can be determined based on which of the communication medium 4, the communication medium 5, and the communication medium 6 the system activation request has passed.

In the case of the master node (step A in FIG. 3)
1 (YES branch), mounts the installation master medium of the own node (step A4 in FIG. 3), and shifts to execution of the installation procedure (step A7 in FIG. 3).

Next, it is determined whether or not there is an installation master medium in the system configuration of the own node (step A2 in FIG. 3). If an installation master medium exists in the system configuration of the own node (YES in step A2 in FIG. 3)
(Branch), and mount the installation master medium (Step A3 in FIG. 3).

If there is no installation master medium in the system configuration of the own node (NO branch of step A1 in FIG. 3), the installation master medium of the parent node is mounted (step A5 in FIG. 3).

Next, the installation procedure and the configuration information are downloaded from the parent node and stored in the disk (step A6 in FIG. 3).

Finally, the installation procedure of the own node is executed (step A7 in FIG. 3). Note that the processing in each step in FIG. 3 is realized by program control executed on a computer (processor) constituting a node.

FIG. 4 is a flowchart showing the procedure of the installation procedure in step A7 of FIG.

First, the master node (node 10 in FIG. 1)
In the case of 1), the configuration information prepared in advance (FIG. 1)
The installation procedure (103 in FIG. 1) is executed using (104) as an input file.

Nodes other than the master node (20 in FIG. 2)
1, 211, 301, 311, 321 and 331) are the configuration information (204, 214, and FIG. 2 in FIG. 2) downloaded from the parent node that instructed the node to start.
304, 314, 324, and 334) as input files, and installation procedures (203, 213, 303, 313, 323, and 323 in FIG. 2) downloaded from the parent node.
33) is performed.

First, the node number of the node is detected (step B1 in FIG. 4). This node number is a number uniquely assigned in the cluster system. As the node number, for example, a communication mechanism (1 in FIG. 2)
013) has a MAC (Media Access Control) −
An ID, a serial number held by the node itself, and a node number embedded in hardware for a cluster system are used.

Next, the node (101, 20 in FIG. 2)
1, 211, 301, 311, 321 and 331) are the downloaded configuration information (104, 204 and 21 in FIG. 2).
4, 304, 314, 324, and 334) (step B2 in FIG. 4).

Next, the node determines whether or not a child node exists (step B3 in FIG. 4). If there is a child node, a request is made to the child node to start in the installation mode (step B8 in FIG. 4).

Next, the node (101, 20 in FIG. 2)
1, 211, 301, 311, 321 and 331) are configuration information (104, 204, 214, 304 and 31 in FIG. 2).
4, 324, 334), the installation parameters are determined using the node number as a key (step B4 in FIG. 4). The contents determined by the installation parameters include the SCS of the disk to be installed.
There are an I-ID, a LUN (Logical Unit Number), an IP (Internet Protocol) address of a communication mechanism, a node name, and the like.

Next, the node (101, 20 in FIG. 2)
1, 211, 301, 311, 321 and 331) are connected disks (102, 202, 212 and 30 in FIG. 2).
2, 312, 322, and 332) (FIG. 4)
Step B5). In this step, in order to install the system, an installation area is secured (1021 in FIG. 2), and initialization is performed.

Next, the installation package is installed (Step B6 in FIG. 4). The installation package is an installation package (107, 207, and 207 in FIG. 1) included in the installation master medium of the own node.
217) or the terminal node (301, 311, 32 in FIG. 1)
In the case of (1, 331), the installation package of the parent node is loaded on the disk. Note that the package loaded in this step does not operate even if the system is started as it is because the environment files and the like remain at the initial values.

Note that the process for loading the installation package generally requires the most time,
In order to perform parallel processing at each node, it is necessary to make a request to start a child node (step B8 in FIG. 4) before loading this package.

Finally, the environment file is set (FIG. 4
Step B7). In this step B7, based on the value determined in the determination of the installation parameter (step B4 in FIG. 4), the value of the initial value is changed, and the value unique to the node (for example, the IP address, the node name, the file system, etc.) is changed. Settings file for mounting). As a result, an environment that operates when the system is started is created. The processing of each step of the installation procedure of FIG. 4 is realized by program control executed on a computer (processor) constituting a node.

[0074]

As described above, according to the present invention,
The following effects are obtained.

A first advantage of the present invention is that the installation procedure for installation can be easily modified in a cluster system.

The reason is that, in the present invention, the cluster has a multi-stage cluster configuration, and when the system is started, the installation procedure of the parent node is duplicated and executed in its own node. This is because, as long as it is reflected, the modified contents are reflected in the installation procedure executed on each child node at the time of installation.

A second effect of the present invention is that the configuration information for installation needs to be placed only in one place on the master node, and the configuration information can be centrally managed.

The reason is that, in the present invention, the cluster has a multi-stage cluster configuration, and when the system is started, the configuration information of the parent node is duplicated and held in the own node, and the node specific information is given. This is because the environment information (environment file) can be set.

A third effect of the present invention is that the time required for installation can be reduced.

The reason for this is that, in the present invention, the cluster is configured as a multi-stage cluster, and the process of activating the child node is performed before the installation of the package that requires the longest time for download, so that the child node and the parent node can be connected. Installation procedures can be executed in parallel,
That's why. Further, in the present invention, the nodes in each cluster can also execute the installation procedure in parallel.
