Corrective Action

(None).

Syslog Message

Read of DR partner’s mailbox successful.

Parameters

(None).

mcc.config.enableDrMirror

Corrective Action

(None).

Syslog Message

(None).

Parameters

(None).

mcc.config.enableMirrorMem

Severity

mcc.config.headswapComplete

Severity

NOTICE

Description

This message occurs when headswap update completes successfully on a node.

Corrective Action

(None).

Syslog Message

(None).

Parameters

(None).

mcc.config.headswapMsgSent

Severity

NOTICE

Description

This message occurs when a headswap HA message is successfully sent to a partner node.

Corrective Action

(None).

Syslog Message

(None).

Parameters

role (INT): Role of the node.

mcc.config.headswapNoNotify

Severity

ERROR

Description

This message occurs when the MetroCluster(tm) node cannot communicate with one or more of its partners after a headswap. In a MetroCluster configuration, partners need to be informed of the old and new system ID of the local node through an HA message, so that they use the correct partner system ID during disaster recovery(DR) operations. Data ONTAP® takes appropriate recovery actions.

Corrective Action

Other than making sure that all of the partners are online, there is no explicit user intervention required; the node automatically retries the operation at regularly scheduled intervals (every 30 seconds).

Syslog Message

Local node system ID changed from %d to %d. Local node could not inform its HA or DR partner node of this change due to error %s.

Parameters

old_system_id (INT): Old system ID of the node.
new_system_id (INT): New system ID of the node.
error (STRING): Internal error description identifying the reason for the failure.

mcc.config.headswapPartnerEr

Severity

ERROR

Description

This message occurs when the partner returns a failure during a MetroCluster(tm) headswap configuration update. This can be due to configuration mismatches on the remote partner, disk ownership reassignment failure, or persistent storage write failure.

Corrective Action

This could potentially be because the partner that failed was not fully functional or was operating in a degraded state. Make sure that the partner is online by issuing the "metrocluster show" command. The partner configuration update will be retried at regular intervals automatically. If the problem persists, contact NetApp technical support.

Syslog Message

Partner %s failed to update configuration due to error %s.

Parameters

partner (STRING): Name of the partner node.
error (STRING): Error description returned by the partner.

mcc.config.headswapRevert
