1.4.6 How to Verify Existing Shared Disks

If you are upgrading from a previous release of CVM to CVM 2.2.1, verify that your shared disk groups still exist:

1. Start the cluster on all nodes.

2. Type the following command on all nodes:

   # vxdg list

   This should display the shared disk groups that existed before. DRL logs that were created with earlier versions of CVM may be too small for CVM 2.2.1. For additional information, refer to "2.1.4 Dirty Region Logging and CVM".
