11.6 Expanding EVMS Volumes on Shared Disks
As your storage needs increase, it might become necessary to add more disk space or drives to your
shared storage system. EVMS provides features that allow you to expand or move existing volumes.
The two supported methods for creating additional space for an existing volume are:
Section 11.6.1, “Expanding a Volume to a Separate Disk,” on page 176
Section 11.6.2, “Moving a Volume to a Larger Disk,” on page 177
