Monitor Knowledgebase

Summary

The disk array status is reporting a critical status. The system is still operational, but a cluster failover might be triggered for this node if the secondary drive in the array fails as well.

Causes

This is typically caused by a disk failure, or an issue in the RAID array.

The vendor's hardware agent is reporting this status in the component's disk_rollup_status property. For more details, view the disk_rollup_status property in the PDW Admin Console or query the sys.dm_pdw_component_health_status DMV.

Resolutions

Contact Microsoft Support and provide them with the alert name and details.

To diagnose this issue, Microsoft Support will require Windows administrator access to the PDW Management node in order to access the vendor’s integrated system user interface.

To resolve this issue, Microsoft Support will contact the vendor’s hardware support team. Depending on the problem, the vendor might require physical access to the appliance to replace one or more hard disks.
