DELLEMC Enterprise SI Storage Group Status of Virtual Volume Alert Rule

EMC.SI.LunMaskingView.VirtualVolume.Alert.Rule (Rule)

Alert when unhealthy virtual volumes.

Knowledge Base article:

Summary

This rule checks the status of all the Virtual Volumes within the storage group (LUN masking view / Storage View) 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 virtual volumes 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 virtual volumes. 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 for a storage group (LUN masking view / Storage View) if an unhealthy state occurs for the virtual volume. It can also occur if certain operations, such as migrations, reduce the performance of the virtual volume.

Or an unhealthy state can occur if software operations or hardware failures disable the read or write cache and cause a virtual volume to become degraded.

Resolutions

Check and resolve any issues with the virtual volume's storage group (LUN masking view / Storage View). Wait for performance-reducing operations to complete and then check the state.
