wafl.mcc events

Contributors

wafl.mcc.config.notFound

Deprecated

Deprecated as of version 9.4 as this debug EMS not supported now.

Severity

ERROR

Description

This message occurs when WAFL® does not find the MetroCluster configuration information on this node.

Corrective Action

Run the 'metrocluster check' command to verify the MetroCluster configuration.

Syslog Message

(None).

Parameters

(None).

wafl.mcc.exceed.volcnt.limit

Severity

ERROR

Description

This message occurs when the MetroCluster® volume count limit for this node is reached. No additional volumes can be created on this node unless some existing volumes are moved or destroyed.

Corrective Action

Either destroy some existing volumes or perform a 'volume move' operation to move some existing volumes to a storage aggregate located on a different node to make room for the new ones. Alternatively, you can also create new volumes on a different node to avoid moving or deleting the existing volumes.

Syslog Message

MCC volume count limit of %d reached for this node.

Parameters

max_volcnt (INT): Volume count limit for this node.

wafl.mcc.nso.left.behind

Severity

ERROR

Description

This message occurs when the system aborts a negotiated switchover because an online left-behind aggregate was found on this node.

Corrective Action

Check whether there exists any online left-behind aggregates on this node from a previous switchover or takeover operation. If such an aggregate exists, then perform the corrective actions specified in the earlier EMS messages for the left-behind aggregate to return it to its original owner, and then retry the operation. You can use the "override-vetoes" option to proceed without performing the corrective action.

Syslog Message

One or more online left-behind aggregates exist. Negotiated switchover is canceled.

Parameters

(None).

wafl.mcc.nso.veto.cmode.vols

Severity

ERROR

Description

This message occurs when the system aborts negotiated switchover because a cluster volume was found on an aggregate with Controller Failover (CFO) HA policy.

Corrective Action

Retry the negotiated switchover operation after the volume is deleted or moved to an aggregate with SFO HA policy. The override-vetoes option may be used to proceed without deleting or moving the volume.

Syslog Message

%s %s%s%s%s has a CFO HA policy and contains one or more cluster volumes. Negotiated switchover canceled.

Parameters

type (STRING): Type of object (volume or aggregate).
owner (STRING): Volume owner.
vol (STRING): Volume name.
app (STRING): Application UUID.
volident (STRING): Unique volume identity when the volume name itself is insufficient.

wafl.mcc.sb.left.behind

Severity

ERROR

Description

This message occurs when WAFL® leaves behind an aggregate during MetroCluster(tm) switchback because this aggregate does not meet all the WAFL veto criteria for switchback.

Corrective Action

Correct the issue that caused the aggregate to be left behind, based on the specific reason identified in an earlier EMS message. After correcting the issue, run the 'metrocluster switchback' command to return the aggregate to its original owner.

Syslog Message

Aggregate %s was left behind during switchback.

Parameters

vol (STRING): Name of the aggregate that was left behind.

wafl.mcc.sb.nso.veto.create

Severity

ERROR

Description

This message occurs when the system aborts a switchback or negotiated switchover because a volume create operation is running.

Corrective Action

Retry the switchback or negotiated switchover operation after the volume create operation is complete.

Syslog Message

%s %s%s%s%s is being created. Switchback or negotiated switchover canceled.

Parameters

type (STRING): Type of object (volume or aggregate).
owner (STRING): Volume owner.
vol (STRING): Volume name.
app (STRING): Application UUID.
volident (STRING): Unique volume identity when the volume name itself is insufficient.

wafl.mcc.sb.nso.veto.fence

Severity

ERROR

Description

This message occurs when the system aborts a switchback or negotiated switchover operation because a volume has a fence set.

Corrective Action

A volume in the aggregate is currently fenced for group operations. Retry the switchback or negotiated switchover operation after any group SnapRestore® or mirror transfers are complete. If the problem persists, contact technical support.

Syslog Message

%s %s%s%s%s has a fence set. Switchback or negotiated switchover canceled.

Parameters

type (STRING): Type of object (volume or aggregate).
owner (STRING): Volume owner.

app (STRING): Application UUID.
volident (STRING): Unique volume identity when the volume name itself is insufficient.

wafl.mcc.sb.nso.veto.iron

Severity

NOTICE

Description

This message occurs when the system aborts a switchback or negotiated switchover because wafliron is running.

Corrective Action

Retry the switchback or negotiated switchover operation after wafliron is finished.

Syslog Message

%s %s%s%s%s is running wafliron. Switchback or negotiated switchover canceled.

Parameters

type (STRING): Type of object (volume or aggregate).
owner (STRING): Volume owner.
vol (STRING): Volume name.
app (STRING): Application UUID.
volident (STRING): Unique volume identity when the volume name itself is insufficient.

wafl.mcc.sb.nso.veto.lock

Severity

ERROR

Description

This message occurs when WAFL® vetoes a switchback or negotiated switchover operation because the system cannot obtain an aggregate level lock.

Corrective Action

Retry the switchback or negotiated switchover operation after waiting for other operations on the aggregate to finish.

Syslog Message

Switchback or negotiated switchover vetoed because the system could not obtain a lock on aggregate %s.

Parameters

vol (STRING): Aggregate name.

wafl.mcc.sb.nso.veto.nvsave

Severity

ERROR

Description

This message occurs when WAFL® vetoes a switchback or negotiated switchover operation because there are NVSave files for an aggregate or a flexible volume that must be replayed before the aggregate or flexible volume can be switched back.

Corrective Action

Retry the switchback or negotiated switchover operation after replaying NVSave files (by bringing the aggregate or flexible volume online) or deleting them from the root volume.

Syslog Message

Switchback or negotiated switchover vetoed due to presence of NVSave files for '%s' (FSID %d, UUID %s).

Parameters

vol_type (STRING): Whether this message refers to NVSave files for an aggregate or a flexible volume.
fsid (INT): File system identifier.
UUID (STRING): UUID of the Volume.

wafl.mcc.sb.nso.veto.revert

Severity

ERROR

Description

wafl.mcc.total.maxvvols

Severity

NOTICE

Description

This message occurs in a MetroCluster(tm) configuration when the system cannot configure a FlexVol® volume because the maximum number of volumes has been reached.

Corrective Action

Check whether there exists a left-behind aggregate on this node from a previous switchover or takeover operation. If such an aggregate exists, then perform the corrective actions specified in the earlier EMS messages for the left-behind aggregate to return it to its original owner. Otherwise, either destroy some existing volumes or perform a 'volume move' operation to move some existing volumes to a storage aggregate located on a different node to make room for the new ones.

Syslog Message

Cannot configure FlexVol volume '%s' (UUID %s) in aggregate '%s': There are too many FlexVol volumes on the system.

Parameters

vol (STRING): FlexVol volume name.
uuid (STRING): FlexVol volume unique ID.
aggregate (STRING): Aggregate name.

wafl.mcc.volLimit.exceeded

Deprecated

Deprecated as of version 9.2 as the additional volume count soft limit for MCC is removed. The regular MCC limit based on the setting of node-object-limit is still in place.

Severity

ERROR

Description

This message occurs when the total volume count exceeds the limit supported on this node.

Corrective Action

Bring the number of volumes below the supported limit on this node, either by performing a 'volume move' operation to move the extra volumes to a storage aggregate located on a different node, or by destroying some or all of the unused extra volumes on this node.

Syslog Message

There are more volumes (%d) than the maximum number of volumes (%d) supported on this node for host: %s.

Parameters

numVols (INT): Current number of volumes.
limit (INT): Maximum number of volumes supported.
host (STRING): Host on this node for which the volume limit has been exceeded.
