Severity

INFORMATIONAL

Description

This message occurs when it cannot be determined whether a disk belongs to a root aggregate.

Corrective Action

(None).

Syslog Message

(None).

Parameters

disk (STRING): Name of the disk.
op (STRING): Operation during which this check failed.
status (INT): Status of the check that failed.

mcc.drsom.disk.skipped

Severity

INFORMATIONAL

Description

This message occurs when disaster recovery switchover manager determines that a disk needs to be skipped from an assign request.

Corrective Action

(None).

Syslog Message

(None).

Parameters

disk (STRING): Name of the disk.
op (STRING): Operation during which this check failed.
reason (STRING): Reason why the disk was skipped.

mcc.drsom.fsm.execute

Severity

INFORMATIONAL

Description

This message occurs when the disaster recovery Switchover Monitor(DRSOM) FSM (Finite State Machine) starts processing an event.

Corrective Action

(None).

Syslog Message

DRSOM FSM state is (%s) and it will process the event (%s). Whether this event will be processed for the DR auxiliary partner: (%s)

Parameters

fsm_state (STRING): Current state of the DRSOM FSM.
fsm_event (STRING): Event to be processed by the DRSOM FSM.
DR_aux (STRING): Indication of whether the event will be processed for the DR auxiliary partner.

mcc.drsom.fsm.invalid.state

Severity

ALERT

Description

This message occurs when the disaster recovery (DR) Switchover Monitor (DRSOM) FSM (Finite State Machine) reaches an invalid state.

Corrective Action

If this problem is seen persistently, contact NetApp technical support for assistance in resolving this issue.

Syslog Message

MCC DRSOM FSM state saw an invalid transition from %s to %s.

Parameters

prev_st (STRING): Previous DRSOM FSM state.
st (STRING): Current DRSOM FSM state.

mcc.drsom.fsm.invalidState

Severity

ERROR

Description

This message occurs when an unexpected disaster recovery Switchover Monitor(DRSOM) FSM (Finite State Machine) event is generated.

Corrective Action

This can happen in cases where a new DR operation was issued before the previous one could finish and it might require a forced-recovery operation. Contact NetApp technical support for assistance in resolving this issue.

Syslog Message

DRSOM FSM event (%s) generated in state (%s) will cause an invalid FSM state transition.

Parameters

fsm_event (STRING): DRSOM FSM event.
fsm_state (STRING): DRSOM FSM state in which the event is generated.

mcc.drsom.fsm.sb.rec.pending

Severity

ALERT

Description

This message occurs when the disaster recovery switchover monitor (DRSOM) transitions to a switchback recovery pending state.

Corrective Action

If this node is booting up for the first time after a disaster, no action is required. If not, please check the states of all the nodes and contact NetApp technical support if they are incorrect.

Syslog Message

This node has entered the Switchback Recovery Pending State.

Parameters

(None).

mcc.drsom.fsmState.EarlySb

Severity

INFORMATIONAL

Description

This message occurs when the disaster recovery switchover monitor (DRSOM) recovers from unexpected error conditions by transitioning to perform an early switchback. An early switchback is performed in the following three cases: a node panics while processing a switchover; a node panics or reboots while retrying a switchover operation; or a node either encounters a subsystem failure, panics, or reboots while aborting a switchover operation. The switchover was reverted and the DRSOM state on all nodes is 'normal'.

Corrective Action

(None).

Syslog Message

(None).

Parameters

(None).

mcc.drsom.mbxRecovery

Severity

INFORMATIONAL

Description

This message occurs when the disaster recover Switchover Monitor(DRSOM) FSM (Finite State Machine) state stored persistently in the mailbox is inconsistent with the DRC (DR Coordinator) and has been recovered.

Corrective Action

(None).

Syslog Message

DRSOM FSM state stored in the mailbox is inconsistent with the DRC. It has been recovered and intialized to %s.

Parameters

next_fsm_state (STRING): State to which the DRSOM FSM will be initialized.

mcc.drsom.process.op.fail

Severity

ALERT

Description

This message occurs when the disaster recovery (DR) Switchover Monitor (DRSOM) cannot perform the DR operation.

Corrective Action

If this problem is seen persistently, contact NetApp technical support for assistance in resolving this issue.

Syslog Message

MCC state machine received invalid operation %s while it was in state %s.

Parameters

op (STRING): DR operation issued.
st (STRING): Current FSM (Finite State Machine) state.

mcc.drsom.sbRecSt.change

Severity

INFORMATIONAL

Description

This message occurs when there is a change in the disaster recovery Switchover Monitor(DRSOM) switchback recovery state.

Corrective Action

(None).

Syslog Message

Switchback recovery state changed from (%d) to (%d) due to (%s).

Parameters

old_state (INT): Previous switchback recovery state.
new_state (INT): New switchback recovery state.
reason (STRING): Reason for change of state.

mcc.drsom.sstbl.configErr

Severity

ERROR

Description

This message occurs during switchback processing, when the disaster recovery(DR) partner cannot be contacted to confirm that it is in a valid MetroCluster(tm) configuration state.

Corrective Action

Make sure that the DR partner is online and accessible by this node.

Syslog Message

(None).

Parameters

partner (STRING): Name of the failed partner.

mcc.drsom.sstbl.sanownCompEr

Severity

ERROR

Description

This message occurs during switchback processing, when the disaster recover(DR) partner cannot be contacted to enable or suspend a sanown completion event.

Corrective Action

Make sure that the DR partner is online and accessible by this node.

Syslog Message

(None).

Parameters

operation (STRING): Disable or enable completion event.
partner (STRING): Name of the failed partner.

mcc.drsom.sstblRunFailure

Severity

ERROR

Description

This message occurs when a particular subsystem cannot proceed with the disaster recovery (DR) operation.

Corrective Action

Refer to the subsystem-specific error that would have been logged before this message.

Syslog Message

(None).

Parameters
