## Configuring Signature Mode

Note Converting a SME Disk cluster from a non-signature mode to signature mode will result in writing signatures to all the configured crypto disks. Once the conversion is complete, verify if all the crypto disks and their paths are in online state and verify the signature of the disks.

To convert a cluster to signature mode, follow these steps:

1. In DCNM-SAN Web Client, click the SME tab.

2. Select Clusters in the navigation pane. Click and expand on the desired destination clusters.

The Cluster Details screen is displayed.

3. Click Convert to Signature Mode.

Note You will not see this option for disks that are already in signature mode.

The Signature Mode Conversion screen is displayed.

4. Click Next.

The Convert Cluster screen is displayed.

Once the conversion is complete, ensure there are no failed disks and verify the signature for crypto disks to ensure the signature is correct. For failed disks, see Recovering SME Disks.
