Abstract

The present invention is more particularly directed to a kind of write-in of Rack whole machine cabinets and the method for reading UUID, log in whole nodes in Rack whole machine cabinets simultaneously using host node server, and send write-in/reading UUID information commands to each node simultaneously, each node completes UUID information commands write-in/read operation simultaneously, and each returns to Writing/Reading success response information and return to host node server.The method that the Rack whole machine cabinets write and read UUID, can quickly, it is efficient, operation accurately is synchronized to all nodes in Rack whole machine cabinets, save substantial amounts of manpower and time, substantially increase the operating efficiency of test job.

Description

A method for writing and reading UUID in the whole Rack cabinet

technical field

The invention relates to the technical field of rack-mounted servers, in particular to a method for writing and reading UUIDs in a Rack rack-mounted rack.

Background technique

With the continuous development of technology in the IT field and the introduction of Internet+, Smart Rack is currently the most mature and leading full-rack server that can be flexibly configured and managed centrally. Its form can be divided into computing and storage nodes. Because the number of nodes that the cabinet can accommodate is huge, and there are many cabinets in one computer room.

UUID (Universally Unique Identifier) refers to a number generated on a machine, which is guaranteed to be unique to all machines in the same time and space. Usually the platform provides a generated API. Calculated according to the standard set by the Open Software Foundation (OSF), using the Ethernet card address, nanosecond time, chip ID code and many possible numbers.

UUID is the only identification information of the server. The current Smart Rack server needs to pre-write UUID information when it is tested at the factory or delivered to customers. Therefore, it is very necessary to write or read the UUID information of all nodes in the Smart Rack cabinet.

There are more and more demands for factory preset UUID. If each node is operated separately, it will consume a lot of time and manpower. If there is a method that can configure the entire cabinet synchronously in a short time, it will be greatly improved. Improve work efficiency and enhance the market competitiveness of products.

Based on this, the present invention designs a method for writing and reading UUIDs in the entire Rack cabinet.

Contents of the invention

In order to make up for the defects of the prior art, the present invention provides a simple and efficient method for writing and reading UUIDs in the entire Rack cabinet.

The present invention is achieved through the following technical solutions:

A method for writing and reading UUID in a Rack whole cabinet is characterized in that: all nodes in the Rack whole cabinet are connected to the master node server as slave nodes, comprising the following steps:

(1) The master node server will set the node name and assign IP addresses to the slave nodes in order from bottom to top;

(2) Light up the BMC identification LEDs of each slave node in turn to ensure that the network of each slave node is smooth;

(3) The master node server logs in to all slave nodes, and simultaneously sends instructions to write UUID information to each slave node;

(4) After each slave node successfully writes the UUID information, it returns its respective write success response information to the master node server;

(5) The master node server sends a command to read UUID information to each slave node at the same time;

(6) After each slave node successfully reads the UUID information, it returns its respective read success response information to the master node server.

In the step (1), the master node server sets the node name of each slave node and assigns an IP address, and at the same time modifies the /etc/hosts file under each slave node system, and adds the node name information and IP address information of each slave node to Go to the hosts file to ensure that you can log in with ssh+hostname in the future.

In the step (3), the master node server uses a one-key passwordless access script to configure ssh to automatically log in to each slave node.

In the step (4), each slave node completes the UUID information writing operation according to the write UUID information instruction received from the master node server, obtains the corresponding write success response information, and returns the write success response information to the master node server; After receiving the write success response information returned by all the slave nodes, the master node server sends an instruction to read UUID information to each slave node.

In the step (6), each slave node completes the UUID information reading operation according to the read UUID information instruction received from the master node server, obtains the corresponding read success response information, and returns the read success response information to the master node server; The master node server only needs to receive the read success response information returned by all the slave nodes.

Beneficial effects of the present invention: the method for writing and reading UUID in the entire Rack cabinet can quickly, efficiently and accurately perform synchronous operations on all nodes on the Rack complete cabinet, saving a lot of manpower and time, and greatly improving the Test the productivity of your work.

Detailed ways

In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The method of writing and reading UUID in the Rack whole cabinet is mainly applied to Smart Rack, using the current mainstream Linux Redhat 6.4 as the carrier, scripts written in linux bash language and calling some linux services and tools to implement all nodes To write or read the UUID information, the following uses the 48-node Rack cabinet as an example to illustrate.

The method for writing and reading the UUID of the Rack whole cabinet is to connect all the nodes in the Rack whole cabinet as slave nodes to the master node server, including the following steps:

(1) The master node server will set the node name and assign IP addresses to the slave nodes in order from bottom to top;

In the step (1), the master node server sets the node name of each slave node and assigns an IP address (such as m01/192.168.1.1; m02/192.168.1.2; ...; m48/192.168.1.48), and at the same time modifies the In the /etc/hosts file under the node system, add the node name information and IP address information (192.168.1.1 m01; 192.168.1.2 m02; ...; 192.168.1.48 m48 information) of each slave node to the hosts file to ensure You can log in later using ssh+hostname.

(2) Then pass the command:

for i in {01..48}

do ssh m$i ipmitool chassis identify

Turn on the BMC identification LED of each slave node in turn to ensure that the network of each slave node is smooth;

(3) The master node server logs in to all slave nodes, and simultaneously sends instructions to write UUID information to each slave node;

(4) After each slave node successfully writes the UUID information, it returns its respective write success response information to the master node server;

(5) The master node server sends a command to read UUID information to each slave node at the same time;

(6) After each slave node successfully reads the UUID information, it returns its respective read success response information to the master node server.

In the step (3), the master node server uses a one-key passwordless access script to configure ssh to automatically log in to each slave node.

In the step (4), each slave node completes the UUID information writing operation according to the write UUID information instruction received from the master node server, obtains the corresponding write success response information, and returns the write success response information to the master node server; After receiving the write success response information returned by all the slave nodes, the master node server sends an instruction to read UUID information to each slave node.

In the step (6), each slave node completes the UUID information reading operation according to the read UUID information instruction received from the master node server, obtains the corresponding read success response information, and returns the read success response information to the master node server; The master node server only needs to receive the read success response information returned by all the slave nodes.
