1815 The EBS is deleted from console while managed.

Explanation
This error can occur when a managed Elastic Block Store (EBS) volume is deleted by using the
Amazon Web Services management console. If an EBS that is part of a storage pool is deleted by using
the management console, then the corresponding managed disk goes offline, the storage pool that
contains the managed disk goes offline, and all volumes in the storage pool go offline. All data in
the storage pool is lost, unless no data was stored on the EBS volume, which is unlikely.

User response
Use the rmmdiskgrp -force command to delete the entire storage pool. In the
unlikely event that no data was stored on the EBS volume, use the rmmdisk command
to remove the managed disk from the storage pool.
