Rescue System Cannot Find Devices That Are Managed by EVMS

The Linux rescue system does not automatically activate volume manager support for LVM or EVMS. For example, if you are using EVMS as the volume manager for your system device, you might not be able to see the device in order to mount it under the rescue system.

You must manually activate EVMS in order for the Linux rescue system to detect system devices that are managed by EVMS.
