Dell PowerStore Importing External Storage to PowerStore Guide

Import alerts and error codes

When an import operation fails, the error message indicates the nature of the problem to help you resolve the issue. If you attempt to recover from a failure and do not succeed, the error messages include a numeric code for reference. This code is provided to help your service provider quickly resolve the issue. In certain types of failures, along with error messages, the PowerStore cluster generates import alerts.

Two categories of alerts are generated: critical and minor. Critical alerts are generated for situations that require manual intervention and, for non-disruptive import, automatic recovery has failed some reason. For example, the source system went down while a background copy from the PowerStore cluster was occurring. The import fails because the PowerStore cluster is not able to reach the source volume in the SAN path. Also, the subsequent automatic cancel does not fully succeed because the host could not reach the source system and the source volume could not restore back to its normal state. To recover, bring the source system back up, do any required cleanup, and try the import again. Minor alerts are generated when user intervention is not required but some operation has failed. For example, the import failed because the host did not have the appropriate connections to the destination volume. However, automatic recovery occurred and I/Os were redirected back to the source volume without I/O impact. Resolve the error, and retry the operation.
