DELLEMC Enterprise SI Storage Pool Status of Concrete LUN Alert Rule

EMC.SI.StoragePool.ConcreteLun.Alert.Rule (Rule)

Alert when unhealthy storage volumes in a pool

Knowledge Base article:

Summary

This rule checks the status of all the Concrete LUNs within the storage pool and generates an alert if there is an unhealthy state for any of the LUNs.

Configuration

The alert will contain a list of the first 1024 LUNs in an unhealthy state along with the health state, health state details and operational status. You can override this Maximum Entities value up to a maximum of 8192 LUNs. Smaller values will result in more efficient processing and a smaller alert description, which may be of concern if sending alerts via email or messaging systems or a ticketing system.

Causes

An unhealthy state occurs if an unhealthy state occurs for a storage pool provisioned from the LUN. It can also occur if certain operations, such as migrations, reduce the performance of the LUN.

On VNX block systems a LUN becomes degraded if trespassed by its storage processor. Or an unhealthy state can occur if software operations or hardware failures disable the read or write cache and cause a LUN to become degraded.

Resolutions

Check and resolve any issues with the LUN's storage pool. Wait for performance-reducing operations to complete and then check the state. If applicable, try to trespass the LUN back to its storage processor.
