Summary

The disk array is reporting an unexpected status. The severity cannot be determined. This alert indicates the array is in an unexpected state, but the system appears to be operational.

Causes

This is caused by a disk warning 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.

The disk_rollup_status is reported by the vendor’s hardware agent.

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 affected PDW Host node in order to access the vendor’s integrated system user interface.
