Node Resource Management

Function

The Node Resource Management page allows you to set multiple active and standby nodes for a resource pool. Failover is supported, that is when an active node fails, its stateless computing profile automatically migrates to a standby node.

Table 1 describes the button on the Node Resource Management page, and Table 2 describes the parameters.

**Table 1** Button
Button	Description
Add Resource Pool	You can set the Resource Pool Name, Associated Profile, Migration Conditions, and Associated Compute Node of a created resource pool. A maximum of 64 resource pools are supported.

**Table 2** Parameters
Parameter	Description
Resource Pool Name	Name of a compute node resource pool. The name can contain letters, digits, and underscores (_) and cannot exceed 15 characters. The first character cannot be an underscore.
Associated Profile	Common profile associated with a compute node resource pool. This field can be empty.
Active Nodes	Compute nodes associated with profiles.
Standby Nodes	Standby nodes are not associated with stateless computing profiles. If an active node fails, its associated profile will automatically migrate to a standby mode. If a standby node with a migrated profile fails, the profile will not migrate again. Standby nodes do not occupy MAC addresses of the MAC address pool of the associated common profile.
Running Standby Nodes	Standby nodes that have replaced faulty active nodes.
Abnormal Nodes	Active or standby nodes that meet the migration conditions. If a node becomes abnormal, it is disassociated from its profile.
Migration Status	Status of data migration from a faulty active node to a standby node. Statues are "migration succeeded", "migration failed", and "not migrated".
Migration Conditions	Events that trigger active/standby switchovers. At least one condition is required.
Operation	Operations you can perform on a resource pool. : Edit a resource pool. : Changes an active node. Before the change, the new node is not associated with any stateless computing profile or compute node resource pool. The original active node will be restarted and the new node may be restarted. : Change the role of a compute node. : Delete a resource pool.
