raid.mcc.disasterSummary

Severity: INFORMATIONAL
Description: This message reports the summary information for the MetroCluster(tm) switchover operation.
Corrective Action: (None).
Syslog Message: RAID switchover summary: number of DR aggregates=%d number of mirrored aggregates=%d number of unmirrored aggregates=%d number of out-of-date aggregates=%d number of mirrored aggregates with both plexes online=%d number of offline aggregates switched over=%d
Parameters: nTotalAggrs (INT): Number of DR aggregates switched over.
nMirAggrs (INT): Number of mirrored aggregates switched over.
nUnmirAggrs (INT): Number of unmirrored aggregates switched over.
nOodPlexes (INT): Number of mirrored aggregates with out-of-date plexes.
nMirComplete (INT): Number of mirrored aggregates with both the plexes online during switchover.
nOfflineAggrs (INT): Number of offline aggregates switched over.

raid.mcc.heal.aggrs.canceled

Severity: ERROR
Description: This message occurs when a 'metrocluster heal -phase aggregates' operation is canceled due to the presence of left-behind high-availability (HA) aggregates.
Corrective Action: Giveback still in progress can cause this condition. To see if this is the case, execute 'storage failover show-giveback'. If it is in progress, wait until it completes and retry the 'metrocluster heal -phase aggregates' command. If giveback is not in progress then execute a 'storage failover giveback -ofnode' from the node currently hosting the left-behind aggregate. After this is complete, retry the 'metrocluster heal -phase aggregates' command.
Syslog Message: Aggregate %s homed on %s is a %s, canceling heal aggregates operation.
Parameters: aggregate (STRING): Name of the aggregate
home_owner_name (STRING): Name of the node home to the left behind aggregate.
reason (STRING): Activity that is preventing heal aggregates operation.

raid.mcc.heal.roots.canceled

Severity: ERROR
Description: This message occurs when a 'metrocluster heal -phase root-aggregates' operation is canceled because a switched over root aggregate is busy with another configuration operation. An ongoing configuration operation can cause this condition.
Corrective Action: Wait a few minutes, then retry the 'metrocluster heal -phase root-aggregates' command.
Syslog Message: Aggregate %s is busy with another configuration operation. Canceling heal root-aggregates operation.
Parameters: aggregate (STRING): Name of the aggregate.
reason (STRING): Activity that is preventing the heal root-aggregates operation.

raid.mcc.ISL.down

Severity

ERROR

Description

This message occurs when a MetroCluster(tm) DR operation other than disaster switchover is canceled because remote site storage is not visible; this can happen if the Inter-Switch Links are down.

Corrective Action

Verify remote cluster connectivity. Use the "storage switch add -switch-ipaddress <switch-ip-address>" command to start monitoring the switches if not already so. Then use the "storage switch show -port" and "storage switch show -san-config" commands to verify FC connectivity to the remote site. 2. Retry the operation. If the error persists, contact technical support for assistance.

Syslog Message

%s was canceled because remote site storage is not visible; Inter-Switch Links might be down.

Parameters

operation (STRING): The DR operation which was canceled.

raid.mcc.leftBehindAggr

Severity: NOTICE
Description: This message occurs when an aggregate is not returned to its original owner in a switchback operation.
Corrective Action: Run the 'metrocluster switchback' command to return the aggregate to its original owner. If the condition persists, contact NetApp technical support.
Syslog Message: Aggregate %s was left behind during switchback.
Parameters: aggregate (STRING): Name of the aggregate that was left behind.
aggregate_uuid (STRING): Universal Unique Identifier(UUID) of the aggregate.
home_owner_id (LONGINT): NVRAM system ID of the aggregate's home owner.
current_owner_id (LONGINT): NVRAM system ID of the aggregate's current owner.
dr_home_owner_id (LONGINT): NVRAM system ID of the aggregate's disaster recovery(DR) home owner.

raid.mcc.leftBehindSpare

Severity: NOTICE
Description: This message occurs when a spare disk is not returned to its original owner in a switchback operation.
Corrective Action: Run the 'metrocluster switchback' command to return the disk to its original owner.
Syslog Message: Disk %s was left behind during switchback.
Parameters: disk (STRING): Name of the disk that was left behind.
disk_uuid (STRING): Universal Unique Identifier(UUID) of the disk.
home_owner_id (LONGINT): NVRAM system ID of the disk's home owner.
current_owner_id (LONGINT): NVRAM system ID of the disk's current owner.
dr_home_owner_id (LONGINT): NVRAM system ID of the disk's disaster recovery(DR) home owner.

raid.mcc.nso.canceled

Severity: ERROR
Description: This message occurs when a MetroCluster negotiated switchover is canceled due to activity in RAID on a volume or aggregate.
Corrective Action: Reissue the 'metrocluster switchover' command after the pending or in-progress operation on the aggregate is complete. The 'override-vetoes' option may be used to proceed without waiting for the pending or in-progress operation to complete.
Syslog Message: Aggregate %s is %s, canceling negotiated switchover.
Parameters: aggregate (STRING): Name of the aggregate.
reason (STRING): Activity that is preventing negotiated switchover.

raid.mcc.nso.dr.leftbehind

Severity: ERROR
Description: This message occurs when a MetroCluster switchover is canceled due to the presence of left behind aggregates from a switchback operation.
Corrective Action: If the aggregate is not in a "failed" or "limbo" state, issue the 'metrocluster switchback' command to return the aggregate to its original owner. Reissue the 'metrocluster switchover' command.
Syslog Message: Aggregate %s was left behind from a switchback operation, canceling negotiated switchover.
Parameters: aggregate (STRING): Name of the aggregate that was left behind.
aggregate_uuid (STRING): Universal Unique Identifier of the aggregate.
home_owner_id (LONGINT): NVRAM system ID of the aggregate's home owner.
current_owner_id (LONGINT): NVRAM system ID of the aggregate's current owner.
dr_home_owner_id (LONGINT): NVRAM system ID of the aggregate's disaster recovery home owner.

raid.mcc.nso.ha.leftbehind

Severity: ERROR
Description: This message occurs when a MetroCluster switchover is canceled due to the presence of left behind aggregates from a giveback operation.
Corrective Action: If the aggregate is not in a "failed" or "limbo" state, issue the 'storage failover giveback' command to return the aggregate to its original owner. Reissue the 'metrocluster switchover' command.
Syslog Message: Aggregate %s was left behind from a giveback operation, canceling negotiated switchover.
Parameters: aggregate (STRING): Name of the aggregate that was left behind.
aggregate_uuid (STRING): Universal Unique Identifier (UUID) of the aggregate.
home_owner_id (LONGINT): NVRAM system ID of the aggregate's home owner.
current_owner_id (LONGINT): NVRAM system ID of the aggregate's current owner.
