Parameters

service-instance-group-name: Specifies a service instance group by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a service instance group, this command displays information about all service instance groups.

Examples

# Display information about all service instance groups.

<Sysname> display service-instance-group

Service instance group information:

  Service instance group: bb

    Type          : Default

 

  Service instance group: sgrp

    Type          : Default

    Failover group: failgrp (Default)

    Failover group: test (Default)

  Total service instance groups: 2

# Display information about the service instance group sgrp.

<Sysname> display service-instance-group sgrp

    Type          : Default

    Failover group: failgrp (Default)

    Failover group: test (Default)

Table 1 Command output

Field	Description
Service instance group	Name of the service instance group.
Type	Failover group type: ·     Default. ·     WAAS—A WAAS-type failover group is used for service backup of only WAAS-type cards. For the failover group to operate correctly, make sure the service instance group and the associated failover group have the same type.
Failover group	Name of the failover group associated with the service instance group (failover group type): ·     Default. ·     WAAS—A WAAS-type failover group is used for service backup of only WAAS-type cards. For the failover group to operate correctly, make sure the service instance group and the associated failover group have the same type. This field is displayed only when a failover group is associated with the service instance.
Total service instance groups	Total number of service instance groups.

 

failover-group

Use failover-group to associate a failover group with the service instance group.

Use undo failover-group to remove the association between the failover group and the service instance group.

Syntax

failover-group failover-group-name

undo failover-group failover-group-name

Default

A service instance group is not associated with any failover groups.

network-admin

Parameters

failover-group-name: Specifies a failover group by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

For inter-system service backup, you can associate a service instance group with only one failover group. The nodes in the failover group must belong to different systems.

For intra-system service backup, you can associate a service instance group with one or multiple failover groups. The nodes in the failover groups must belong to the same system.

·     If you associate a service instance group with one failover group, the nodes in the failover group perform application module service backup.

·     If you associate a service instance group with multiple failover groups, application module service backup loads are distributed among the failover groups. Each failover group also backs up services between its nodes. The number of failover groups that can be associated with a service instance group varies by application module.

For more information about failover groups, see High Availability Configuration Guide.

After specifying a service instance group for an instance, you are not allowed to remove the association between the service instance group and failover group.

The type of the service instance group must be the same as the type of failover groups associated with the service instance group.

Examples

# Associate failover group test with service instance group abc.

<Sysname> system-view

[Sysname] service-instance-group abc

[Sysname-service-instance-group-abc] failover-group test

# Associate failover groups test1 and test2 with service instance group abc.

<Sysname> system-view

[Sysname] service-instance-group abc

[Sysname-service-instance-group-abc] failover-group test1

[Sysname-service-instance-group-abc] failover-group test2

Parameters

service-instance-group-name: Specifies a service instance group by its name, a case-sensitive string of 1 to 31 characters.

type: Specifies a service instance group type. If you do not specify this keyword, the created service instance group is the default type.

default: Specifies the default type.

waas: Specifies the WAAS type. A WAAS-type service instance group is used for service backup of only WAAS-type cards. A WAAS-type service instance group supports only intra-system service backup between WAAS cards, and it does not support inter-system service backup.

Usage guidelines

You can associate a service instance group with multiple failover groups, and make sure the failover groups are the same type.

After specifying a service instance group for a service module, you are not allowed to delete the service instance group.

Examples

# Create service instance group sgrp and enter its view.

<Sysname> system-view

[Sysname] service-instance-group sgrp

[Sysname-service-instance-group-sgrp]
