Description

This document attempts to explain the steps required to export the EMC DeviceGroup content from the Production server to the Media server.

In this instance, the EMC DeviceGroup "EMC-CDS-Prod-dg" consists of "10" EMC STD devices, along with "10" EMC BCV related devices.

Veritas Volume Manager (VxVM) view of BCV devices on Linux Media server:

There are "10" EMC BCV devices presented to the Linux server.

Note: As of 5.0 MP3 VxVM is "hardware technology" aware. In this instance, it can detect the presence of EMC BCV devices.
 

At this time, the Media Server which is a LINUX based server cannot see the BCV configuration from the Production server.


Media Server:


# ./symdg list

No Symmetrix device groups were found


Production Server:
 

On the Production server create a file containing the EMC DeviceGroup content for "EMC-CDS-Prod-dg"


First list the EMC DeviceGroup details for "EMC-CDS-Prod-dg".
