Creating an ECS and a DWS Cluster Creating an ECS Creating a DWS Cluster Parent topic: Test Methods
Unbinding an EIP from an ECS Scenarios This section describes how to unbind an EIP from an ECS by calling APIs. Prerequisites You have created an ECS. For details, see Purchasing an ECS. If you use a token for authentication, you must obtain the token and add X-Auth-Token to the request
ECS Specifications Used by MRS MRS uses ECSs of the following types in different application scenarios. General computing-plus: C3, C3ne, C6, and C6s Memory-optimized: M3, and M6 Ultra-high I/O: I3 and IR3 Kunpeng general computing-plus: KC1 ECS Flavor Naming Rules AB.C.D Example:
Migrating an OS to HCE 2.0 Constraints Migrating Procedure Conflicting Packages Parent topic: Migrating an OS
Upgrading HCE and RPM Packages Upgrade Overview Using dnf or yum for Upgrade and Rollback Upgrade Using OSMT Appendixes
Viewing Event Messages on the ECS Return to the CloudShell terminal console page opened in Purchasing an ECS. Since httpsserver.py has been started, CloudShell will print event information. Figure 1 Event message Parent topic: Implementation Procedure
Changing an ECS Non-Administrator Password You can use the Change ECS Non-Administrator Password card to change the password of a non-administrator user. Prerequisites UniAgents have been installed for all ECSs, and are in the running state. Creating a Task for Changing the ECS Non-administrator
ECS Event Handling Suggestions ECS Event Overview On the CCE console, you can use ECSs as nodes to create highly available Kubernetes clusters. During routine O&M, hardware and software faults on hosts accommodating ECSs are proactively forecasted and prevented by Huawei Cloud. If
Configuring DCS Instance Tags Tags facilitate DCS instance identification and management. Tags can be added in instance creation, or added or deleted for an instance later. If your organization has configured tag policies for DCS, add tags to DCS instances based on the tag policies
Diagnosing a DCS Redis Instance If a fault or performance issue occurs, you can ask DCS to diagnose your instance to learn about the cause and impact of the issue and how to handle it. Notes and Constraints DCS Redis 3.0 and Memcached instances do not support diagnosis. New instances
Accessing a DCS Redis Instance Configuring Redis Network Connections Controlling DCS Redis Access Connecting to Redis on a Client Connecting to Redis on the Console Public Access to a DCS Redis 3.0 Instance (Discontinued)
Clearing DCS Instance Data To clear instance data, use the FLUSHDB or FLUSHALL commands on accessed instances, or the data clearance function on the DCS console. This section describes how to use the function to clear instance data with one click. Clearing instance data may cause
Exporting a DCS Instance List A list of instance information can be exported and downloaded in Excel on the DCS console. You can view or compare DCS instance information. Procedure Log in to the DCS console. Click in the upper left corner of the console and select the region where
Viewing DCS Background Tasks After you initiate certain instance operations such as scaling up the instance and changing or resetting a password, a background task will start for each operation. On the DCS console, you can view the background task status and clear task information
DCS Data Migration Overview The DCS console supports online and backup (file) migration with intuitive operations. Incremental data can be migrated online. Online migration is suitable when the source Redis instance supports the SYNC and PSYNC commands. Data in the source Redis instance
Applying for More DCS Quotas What Is Quota? A quota is a limit on the quantity or capacity of a certain type of service resources that you can use, for example, the maximum number of DCS instances that you can create and the maximum amount of memory that you can use. If a quota cannot
Buying a DCS Redis Instance Fully compatible with open-source Redis, Distributed Cache Service (DCS) for Redis is a high-speed in-memory data processing engine provided by Huawei Cloud. You can purchase Redis instances with specific computing power and storage space as needed. Video
Modifying DCS Instance Specifications On the DCS console, you can change DCS Redis or Memcached instance specifications including the instance type, memory, shard quantity, and replica quantity. Modifying instance specifications does not affect the connection address, password, security
DCS Backup and Restoration Overview There is a small chance that dirty data could exist in a DCS instance owing to service system exceptions or problems in loading data from persistence files. In addition, some systems demand not only high reliability but also data security, data
