Symptoms

While volume import sessions are in progress into a PowerStore cluster, controller failovers on the Dell EqualLogic storage array may occur. These controller restart events can lead to automatic import session cancellation. Also, they may cause a rollback of the import session.

The purpose of this article is to provide the resolution to recover from the Host I/O failure and Import failure issue.

Cause

PowerStore import session cancellation and rollback can occur during controller failover or controller restart events on the source Dell EqualLogic storage array. These events happen while PowerStore volume import sessions are in progress.

Resolution

  2. Retry the Import operation
