Adjusting OceanStor 9000's zones and zone attributes

0

Procedure for adjusting OceanStor 9000's zones and zone attributes:
1. Log in to DeviceManager.
2. Check licenses in the storage system.
Load balancing provided by the InfoEqualizer feature is a value-added feature, so you must ensure that each license file in the storage system includes information about InfoEqualizer.
Choose Settings > License Management > Active License and check whether the activated licenses contain information about InfoEqualizer. If information about InfoEqualizer is not contained, follow the displayed instructions to import and activate the required license.
3. Create a zone. OceanStor 9000 has a default zone root. Administrators can create more zones based on service requirements. The owning subnet of a zone can be configured using the subnet CONFIGURE item in zone CONFIGURE.
a. Choose Settings > Cluster Settings > InfoEqualizer > Zone Management.
b. Click Create. In the Create Zone dialog box, enter the required information and click OK.
4. Migrate nodes. After zones are created, nodes can be migrated from the root zone to other newly created zones.
a. In the zone list, select a newly created zone.
b. Click Add above the node list.
c. In the Add Node dialog box that is displayed, select nodes that you want to migrate to the zone and click OK.
Note: The Add Node dialog box displays nodes in the root zone.

Adjusting the number of nodes in an OceanStor 9000 zone
You can adjust the number of nodes in a zone. You are advised to retain at least two nodes in a zone for fault failover. Note that when you access file sharing services using a dynamic domain name or a static domain name specified in InfoEqualizer, you are connected to a node in the default zone root. If you migrate all nodes from the default zone to a newly created zone, you can only access file sharing services using the domain name of the newly created zone. The file sharing services cannot be accessed using a dynamic domain name or a static domain name specified in InfoEqualizer.

Concept of a zone of OceanStor 9000
Different zones provide different services. A zone contains a group of nodes that have the same dynamic domain name, static domain name, and automatic load balancing mode. The system has a default zone root. This zone contains all system nodes. You can create new zones and add nodes to them.

Benefits of dividing different zones for OceanStor 9000
Zones enable automatic load balancing policies to be flexibly configured for nodes carrying different types of client services, improving service performance. In addition, each client can access a specific zone for fault isolation.

Maximum number of zones supported by the OceanStor 9000 InfoEqualizer feature
The maximum number of zones supported by the OceanStor 9000 InfoEqualizer feature is 32.

Can I Adjust the Number of Nodes in a Zone?
You can adjust the number of nodes in a zone. You are advised to retain at least two nodes in a zone for fault failover. Because using InfoEqualizer Dynamic domain name or Static domain name can only access nodes in root zone. If you migrate all nodes from the root zone to newly created zones, file sharing services can be only accessed using domain names of the newly created zones. InfoEqualizer Dynamic domain name or Static domain name cannot be used to access file sharing services.
