1.4.5 Configuring Shared Disks

If you are installing CVM for the first time or adding disks to an existing cluster, you must configure new shared disks. If you are upgrading CVM, verify that your shared disks still exist.

The shared disks should be configured from one node only. Since the CVM software cannot tell whether a disk is shared or not, you must specify which are the shared disks.

Make sure that nobody else is accessing the shared disks from another node while you are performing the configuration.
