## Recovering SME Disk when Data Preparation Fails

When data preparation fails, SME Disk puts the disk in a failed state. The disk is not accessible to hosts and all paths of the disk are put in I/O reject state ( reject all host I/Os state). To recover the disk from the failed state, follow these steps:

1. Because the disk is not accessible from the host, restore the contents of the failed disk on the backend storage.

2. Enter the recover command with appropriate arguments to recover the disk to the proper crypto state based on the backup data. For more information on the recover command syntax using CLI, see “Recovering SME Disks” and through the GUI, see “Recovering SME Disks”.

In the Signature mode, the disk can be recovered by using the signature information on the media.
