Chassis Redundancy Group Form

[This is the Context-Sensitive Help topic for the Chassis Redundancy Group form.]

Chassis Redundancy Groups are configured to provide redundancy protection against Chassis failure.

The Chassis Redundancy Group form provides details about the Chassis Redundancy Group you selected. The following table describes the fields included on the Chassis Redundancy Group form. This topic includes the following sections:

For information about each tab: Concept Link IconSee Also

Basic Attributes
Attribute Description
Name

Name assigned to the Chassis Redundancy Group. NNMi uses the Node Name followed by a slash and then the name that is specific to the Device Vendor:

Status

Overall status for the current Chassis Redundancy Group. NNMi follows the ISO standard for status classification.

Possible values are:

  No Status

  Normal

  Disabled

  Unknown

  Warning

  Minor

  Major

  Critical

The icons are displayed only in table views.

Status Last Modified The date and time when the Status value was last modified.

Redundant Components Tab

Chassis Redundancy Groups are configured to provide redundancy protection against Chassis failures.

The Chassis Redundancy Group Form provides details about the selected Chassis Redundancy Group.

Redundant Group Member Chassis
Attribute Description
Redundant Chassis

Table of all of the chassis that are members of this Chassis Redundancy Group. Use this table to access information about each chassis associated with the selected Chassis Redundancy Group.

Double-click the row representing a Chassis. The Chassis Form displays all details about the selected Chassis.

Only parent Chassis can be members of this group, child Chassis are not permitted to participate in Chassis Redundancy Groups.

Incidents Tab

[This is the Context-Sensitive Help topic for the Chassis Redundancy Group form, Incidents tab.]

Chassis Redundancy Groups are configured to provide redundancy protection against Chassis failures.

The Chassis Redundancy Group Form provides details about the selected Chassis Redundancy Group.

Incidents Associated with Chassis in this Redundancy Group
Attribute Description
Incidents

Table of the Incidents associated with the selected Chassis Redundancy Group.

These Incidents are sorted by creation time so that you can view the Incidents in chronological order. Use this table to determine which Incidents are still open for the selected Chassis Redundancy Group.

Double-click the row representing an Incident. The Incident Form displays all details about the selected incident.

See Incident Form for more details about the incident attributes that appear in the incident table's column headings.

Status Tab

[This is the Context-Sensitive Help topic for the Chassis Redundancy Group form: Status tab.]

Chassis Redundancy Groups are configured to provide redundancy protection against chassis failures.

The Chassis Redundancy Group Form provides details about the selected Chassis Redundancy Group.

Chassis Redundancy Group Status History Table
Attribute Description
Status History

List of up to the last 30 changes in the status for the Chassis Redundancy Group. This table is useful for obtaining a summary of the Chassis Redundancy Group Status so that you can better determine any patterns in behavior and activity.

Double-click the row representing a Status History. The Chassis Redundancy Group Status History Form displays all details about the selected Status.

History Form

[This is the Context-Sensitive Help topic for the Redundant Chassis Group Status History form.]

Chassis Redundancy Group Status is derived from SNMP polling results for each Chassis in the Chassis Redundancy Group, as well as any conclusions. For information about how the current Status was determined, see the Chassis Redundancy Group Form: Conclusions Tab. Status reflects the most serious outstanding conclusion. See Watch Status Colors for more information about possible status values.

Status Attributes
Attribute Description
Status

Overall status for the current Chassis Redundancy Group. NNMi follows the ISO standard for status classification. Possible values are:

  No Status

  Normal (one Active card and one Standby card)

  Disabled

  Unknown

  Warning

  Minor

  Major

  Critical

The icons are displayed only in table views.

Status Last Modified Date and time indicating when the Status was last set.

Conclusions Tab

[This is the Context-Sensitive Help topic for the Chassis Redundancy Group form: Conclusions tab.]

Chassis Redundancy Groups are configured to provide redundancy protection against Chassis failures.

The Chassis Redundancy Group Form provides details about the selected Chassis Redundancy Group.

Outstanding Status Conclusion Values
Attribute Description
Outstanding Status Conclusions

The dynamically generated list of summary statuses for the Chassis Redundancy Group that contributed to the current overall Status of the selected Chassis Redundancy Group. Status is set by the Causal Engine.

Each Conclusion listed is outstanding and contributes to the current overall Status.

This table is useful for obtaining a quick summary of the problem description for the current Chassis Redundancy Group that led up to the Chassis Redundancy Group's most current Status.

The Status value is correlated based on the most critical Conclusions.

Double-click the row representing a Conclusion. The Conclusion form displays all details about the selected Conclusion.

The following table describes the possible Conclusions that might appear for a Chassis Redundancy Group object.

Inter switch links (ISL) are Layer 2 connections that connect chassis. The interfaces in these connections are on the same node, but they are associated with ports on different chassis in a Chassis Redundancy Group.

A Y in the Incident? column indicates that the conclusion results in an incident.

Major Status Conclusions

Conclusion Description Status Incident?
StackWithNoSlave No Chassis in the Chassis Redundancy Group has a SLAVE  State. Major Y

Minor Status Conclusions

Conclusion Description Status Incident?
StackDegraded

NNMi has detected the following conditions in the Chassis Redundancy Group:

  • One Chassis with a MASTER State
  • One Chassis with a SLAVE State
  • Other Chassis in the group are not in SLAVE State
Minor Y
