Steps on the Charon Host System

Mounting a Newly Attached Volume Using the Storage Manager (SSP AL only)

After the volume has been attached to the instance, it must be included in the Charon-SSP host system configuration. This On Charon-SSP AL instances, this is achieved via the Charon-SSP Manager.

1. Open the Charon-SSP Manager on your local system and connect to your Charon cloud instance.
2. Select Tools > Azure Cloud > Storage Manager.

   1. Select the new device. 
   2. Click on the cog-wheel symbol.
