ABRL

Available Attribute Relays

BADC, BAMS, BARC, BCLB, BCMN, BLDR, BNMS, BSSM, BDDS

Restore connectivity to a service (an ADC service) running an Attribute Relay Service as soon as possible. If there are no connected attribute relays, the grid node can't report attribute values to the NMS service. Thus, the NMS service can no longer monitor the status of the service, or update attributes for the service.

If the problem persists, contact technical support.

ACMS

Available Metadata Services

BARC, BLDR, BCMN

An alarm is triggered when an LDR or ARC service loses connection to a DDS service. If this occurs, ingest or retrieve transactions can't be processed. If the unavailability of DDS services is only a brief transient issue, transactions can be delayed.

Check and restore connections to a DDS service to clear this alarm and return the service to full functionality.

If this alarm is triggered and network connectivity is good, contact technical support.

AMQS

Audit Messages Queued

BADC, BAMS, BARC, BCLB, BCMN, BLDR, BNMS, BDDS

If audit messages can't be immediately forwarded to an audit relay or repository, the messages are stored in a disk queue. If the disk queue becomes full, outages can occur.

To allow you to respond in time to prevent an outage, AMQS alarms are triggered when the number of messages in the disk queue reaches the following thresholds:

If an AMQS alarm is triggered, check the load on the system—​if there have been a significant number of transactions, the alarm should resolve itself over time. In this case, you can ignore the alarm.

If the alarm persists and increases in severity, view a chart of the queue size. If the number is steadily increasing over hours or days, the audit load has likely exceeded the audit capacity of the system. Reduce the client operation rate or decrease the number of audit messages logged by changing the audit level to Error or Off. See Configure audit messages and log destinations.

AOTE

Store State

BARC

Only available for Archive Node's with a Target Type of Tivoli Storage Manager (TSM).

If the value of Store State is Waiting for Target, check the external archival storage system and ensure that it is operating correctly. If the Archive Node has just been added to the StorageGRID system, ensure that the Archive Node's connection to the targeted external archival storage system is configured correctly.

If the value of Store State is Offline, check the value of Store Status. Correct any problems before moving the Store State back to Online.

If the multipath state alarm appears as "Degraded" (select SUPPORT > Tools > Grid topology, then select site > grid node > SSM > Events), do the following:

ARCE

ARC State

ARC

The ARC service has a state of Standby until all ARC components (Replication, Store, Retrieve, Target) have started. It then transitions to Online.

If the value of ARC State does not transition from Standby to Online, check the status of the ARC components.

If the value of ARC State is Offline, restart the service. If the problem persists, contact technical support.

AROQ

Objects Queued

ARC

This alarm can be triggered if the removable storage device is running slowly due to problems with the targeted external archival storage system, or if it encounters multiple read errors. Check the external archival storage system for errors, and ensure that it is operating correctly.

In some cases, this error can occur as a result of a high rate of data requests. Monitor the number of objects queued as system activity declines.

ARRF

Request Failures

ARC

If a retrieval from the targeted external archival storage system fails, the Archive Node retries the retrieval as the failure can be due to a transient issue. However, if the object data is corrupt or has been marked as being permanently unavailable, the retrieval does not fail. Instead, the Archive Node continuously retries the retrieval and the value for Request Failures continues to increase.

This alarm can indicate that the storage media holding the requested data is corrupt. Check the external archival storage system to further diagnose the problem.

If you determine that the object data is no longer in the archive, the object will have to be removed from the StorageGRID system. For more information, contact technical support.

Once the problem that triggered this alarm is addressed, reset the failures count. Select SUPPORT > Tools > Grid topology. Then select site > grid node > ARC > Retrieve > Configuration > Main, select Reset Request Failure Count and click Apply Changes.

Storage Controller Failed Drive Count

SSM

This alarm is triggered when one or more drives in a StorageGRID appliance has failed or is not optimal. Replace the drives as required.

BASF

Available Object Identifiers

CMN

When a StorageGRID system is provisioned, the CMN service is allocated a fixed number of object identifiers. This alarm is triggered when the StorageGRID system begins to exhaust its supply of object identifiers.

To allocate more identifiers, contact technical support.

BASS

Identifier Block Allocation Status

CMN

By default, an alarm is triggered when object identifiers can't be allocated because ADC quorum can't be reached.

Identifier block allocation on the CMN service requires a quorum (50% + 1) of the ADC services to be online and connected. If quorum is unavailable, the CMN service is unable to allocate new identifier blocks until ADC quorum is reestablished. If ADC quorum is lost, there is generally no immediate impact on the StorageGRID system (clients can still ingest and retrieve content), as approximately one month's supply of identifiers are cached elsewhere in the grid; however, if the condition continues, the StorageGRID system will lose the ability to ingest new content.

If an alarm is triggered, investigate the reason for the loss of ADC quorum (for example, it can be a network or Storage Node failure) and take corrective action.

If the problem persists, contact technical support.

BRDT

Compute Controller Chassis Temperature

SSM

An alarm is triggered if the temperature of the compute controller in a StorageGRID appliance exceeds a nominal threshold.

BTOF

Offset

BADC, BLDR, BNMS, BAMS, BCLB, BCMN, BARC

An alarm is triggered if the service time (seconds) differs significantly from the operating system time. Under normal conditions, the service should resynchronize itself. If the service time drifts too far from the operating system time, system operations can be affected. Confirm that the StorageGRID system's time source is correct.

If the problem persists, contact technical support.

BTSE

Clock State

BADC, BLDR, BNMS, BAMS, BCLB, BCMN, BARC

An alarm is triggered if the service's time is not synchronized with the time tracked by the operating system. Under normal conditions, the service should resynchronize itself. If the time drifts too far from operating system time, system operations can be affected. Confirm that the StorageGRID system's time source is correct.

If the problem persists, contact technical support.

CAHP

This alarm is triggered during installation or expansion to indicate a new data store is joining the grid.

CCNA

Compute Hardware

SSM

This alarm is triggered if the status of the compute controller hardware in a StorageGRID appliance is Needs Attention.

CDLP

Metadata Used Space (Percent)

DDS

This alarm is triggered when the Metadata Effective Space (CEMS) reaches 70% full (minor alarm), 90% full (major alarm), and 100% full (critical alarm).

If this alarm reaches the 90% threshold, a warning appears on the dashboard in the Grid Manager. You must perform an expansion procedure to add new Storage Nodes as soon as possible. See Expand a grid.

If this alarm reaches the 100% threshold, you must stop ingesting objects and add Storage Nodes immediately. Cassandra requires a certain amount of space to perform essential operations such as compaction and repair. These operations will be impacted if object metadata uses more than 100% of the allowed space. Undesirable results can occur.

Note: Contact technical support if you are unable to add Storage Nodes.

After new Storage Nodes are added, the system automatically rebalances object metadata across all Storage Nodes, and the alarm clears.

Also see information about troubleshooting the Low metadata storage alert in Troubleshoot metadata issues.

If the problem persists, contact technical support.

CMNA

CMN Status

CMN

If the value of CMN Status is Error, select SUPPORT > Tools > Grid topology, then select site > grid node > CMN > Overview > Main and CMN > Alarms > Main to determine the cause of the error and to troubleshoot the problem.

If the Storage Node is a StorageGRID appliance, the StorageGRID system indicates that the controller needs attention.

Check hardware components and environment issues for overheated condition. If necessary, replace the component.

DNST

DNS Status

SSM

After installation completes, a DNST alarm is triggered in the SSM service. After the DNS is configured and the new server information reaches all grid nodes, the alarm is canceled.

ECCD

Corrupt Fragments Detected

LDR

An alarm is triggered when the background verification process detects a corrupt erasure-coded fragment. If a corrupt fragment is detected, an attempt is made to rebuild the fragment. Reset the Corrupt Fragments Detected and Copies Lost attributes to zero and monitor them to see if counts go up again. If counts do go up, there might be a problem with the Storage Node's underlying storage. A copy of erasure-coded object data is not considered missing until such time that the number of lost or corrupt fragments breaches the erasure code's fault tolerance; therefore, it is possible to have corrupt fragment and to still be able to retrieve the object.

If the problem persists, contact technical support.

ECST

A queue of messages can indicate that the ADC service is overloaded. Too few ADC services can be connected to the StorageGRID system. In a large deployment, the ADC service can require adding computational resources, or the system can require additional ADC services.

UMEM

Available Memory

SSM

If the available RAM gets low, determine whether this is a hardware or software issue. If it is not a hardware issue, or if available memory falls below 50 MB (the default alarm threshold), contact technical support.

VMFI

Entries Available

SSM

This is an indication that additional storage is required. Contact technical support.

VMFR

Space Available

SSM

If the value of Space Available gets too low (see alarm thresholds), it needs to be investigated as to whether there are log files growing out of proportion, or objects taking up too much disk space (see alarm thresholds) that need to be reduced or deleted.

If the problem persists, contact technical support.

VMST

Status

SSM

An alarm is triggered if the value of Status for the mounted volume is Unknown. A value of Unknown or Offline can indicate that the volume can't be mounted or accessed due to a problem with the underlying storage device.

VPRI

Verification Priority

BLDR, BARC

By default, the value of Verification Priority is Adaptive. If Verification Priority is set to High, an alarm is triggered because storage verification can slow normal operations of the service.

VSTU

Object Verification Status

BLDR

Select SUPPORT > Tools > Grid topology. Then select site > grid node > LDR > Storage > Overview > Main.

Check the operating system for any signs of block-device or file system errors.

If the value of Object Verification Status is Unknown Error, it usually indicates a low-level file system or hardware problem (I/O error) that prevents the Storage Verification task from accessing stored content. Contact technical support.

XAMS

Unreachable Audit Repositories

BADC, BARC, BCLB, BCMN, BLDR, BNMS

Check network connectivity to the server hosting the Admin Node.

If the problem persists, contact technical support.
