When the Storage Devices solution is installed, it adds preconfigured dashboards and alert definitions that you use to monitor and troubleshoot the components in your storage area network.

Storage Devices Solution Dashboards

Dashboard

Purpose

Storage Troubleshooting

View the storage area network topology and health and alerts on specific components.

Storage Component Usage

Provides an overview of the most frequently used objects on SAN and tracks the error count on these objects.

Storage Heatmap

Provides an overview of object performance for predefined limits.

vRealize Operations Manager generates an alert If a problem occurs with the components in the storage area network that the Storage Devices adapter is monitoring.

Storage Devices Solution Alert Definitions

Alert (ID number)

Alert Level

Affected Object Type

Description

Adapter Configuration failed (14)

Critical

Storage Devices Adapter Instance

Triggered when the Storage Devices adapter instance is incorrectly configured because of invalid credentials or inaccessible Fabric CIM or vCenter Server instances.

Clears when the adapter is reconfigured and can successfully communicate with data sources, such as Fabric CIM or vCenter Server .

All Paths Down on some Mounts (8)

Critical

VMWARE: Host System

Triggered by an All Paths Down (APD) situation on one or more mounts on the host system. This generic alert applies when the root cause for APD cannot be attributed to a zone configuration change, host adapter link failure, or switch port failure.

Clears when the APD situation is resolved on the host system.

All Paths Down on some Mounts because HBA is Link down (9)

Critical

VMWARE: Host System

Triggered by an APD situation on one or more mounts on the host system because of a problem with the host adapter.

Clears when the APD situation is resolved on the host system.

All Paths Down On Some Mounts Because Switch Ports connected to the HBAs is Down (10)

Critical

VMWARE: Host System

Triggered by an APD situation on one or more mounts on the host system, because of a problem with the switch port connection to the host adapter.

Clears when the APD situation is resolved on the host system.

All Paths Down On Some Mounts Because Switch Port connected to the Target is Down (11)

Critical

VMWARE: Host System

Triggered by an APD situation on one or more mounts on the host system, because of a problem with the switch port connection to the target port on the array side.

Clears when the APD situation is resolved on the host system.

All Paths Down on some mounts because HBAs are zoned out (19)

Critical

VMWARE: Host System

Triggered by an APD situation on one or more mounts on the host system. This alert indicates a loss of connectivity between the host adapters on the host side and target ports on the array side because of zone configuration changes.

Clears when the APD situation is resolved on the host system.

Datacenter has some HBAs that are not operating at maximum supported speed (4)

Info

VMWARE: Datacenter

Triggered if a connected HBA is not operating at its maximum supported speed.

Clears when the HBA returns to its maximum operating speed.

Fabric CIM Server Configuration failed (16)

Critical

Fabric CIM Server

Triggered if the Storage Devices adapter cannot communicate with the fabric CIM server using the login credentials or URL information provided.

Clears when the adapter can communicate with the fabric CIM server.

HBA Link Failure (1)

Critical

Host Adapter

Triggered when the HBA status changes from Online to LINK DOWN. Clears when the HBA status returns to Online.

HBA Speed dropped (5)

Critical

Host Adapter

Triggered when the operating speed of the host adapter drops compared to a previous reading in the data collection cycle.

Not automatically cleared. A user must manually clear the alert.

High Virtual Lun Resets Or Aborts (3)

Critical

Mount

Triggered if 50 or more virtual LUN resets or aborts occur per minute on the mount object during two consecutive collection cycles.

Clears when the LUN resets or aborts drop to fewer than 50 per minute for two consecutive collection cycles.

IO Latency is above normal (17)

Critical

Mount

Triggered if the HostSpecificMetrics|IOLatency metric exceeds the dynamic threshold. vRealize Operations Manager sets the dynamic threshold based on the historic data values of this metric.

Clears when the metric values fall below the dynamic threshold.

Multiple ports on the Switch are down (13)

Critical

Switch

Triggered when 50 percent or more switch ports become disabled or display the Enabled but offline status.

Clears when the percentage of unavailable switch ports falls below 50 percent.

No VASA providers registered to vCenter. Cannot discover array objects. (18)

Warning

Storage Devices Adapter Instance

Triggered when no VASA providers are registered to the vCenter Server.

Clears when at least one VASA provider is registered to the vCenter Server.

Number of active paths is low. (15)

Automatic

Mount

Triggered when the HostSpecificMetrics|PathHealthRatio metric for the mount object falls below thresholds. vRealize Operations Manager sets the alert level based on the value of pathHealthRatio:

75<=pathHealthRatio<100 indicates Immediate

50<=pathHealthRatio<75 indicates Warning

pathHeathRatio< 50 indicates Critical

Clears when pathHealthRatio value becomes 100 for all the host system instanced metric groups of the mount object.

Permanent Device Loss on a Mount/Storage Lun (12)

Critical

VMWARE: Host System

Triggered when one or more mounts on the host system is unavailable. This situation occurs if the underlying storage LUN is unmasked or removed from the host system.

If the storage LUN was unmasked without first detaching it from the host system, the alert clears when the mount object becomes available.

If the storage LUN was permanently removed, the alert does not automatically clear. A user must manually clear the alert.

Storage Lun Thin Provisioned Capacity At Critical Levels (6)

Critical

Storage Lun

Triggered when the thin provisioning capacity on the storage LUN reaches a critical level. Thresholds for thin provisioning are set in the vCenter Server.

Clears when the vCenter Server sends the clear event to the Storage Devices adapter.

Storage Lun Thin Provisioned Capacity Threshold At Warning Level (7)

Warning

Storage Lun

Triggered when the thin provisioning capacity on the storage LUN reaches a warning level. The thresholds for thin provisioning are set in the vCenter.

Clears when the vCenter sends the clear event to the Storage Devices adapter.

Switch Port Down Failure (2)

Critical

Switch Port

Triggered when the status of switch port changes to Disabled or Enabled but Offline.

Clears when the switch port status returns to Enabled.
