Configuring volumes, volume trees, SDCs, and snapshots
This section contains procedures for adding, removing, and managing volumes and
snapshots. It explains how to remove volumes, create snapshots, and set volume
bandwidth and IOPS limits. It also describes setting the SDC restriction mode and how
to approve SDCs before mapping volumes.
Adding volumes
Add volumes to a system.
Before you begin
There must be at least three SDS nodes in the system and there must be sufficient
capacity available.
Note: For the minimum size of an SDS, see "System requirements".
About this task
The adding and mapping volume process is necessary, as part of the getting started
process, before applications can access the volumes. In addition, you may create

layer.
You can configure the caching option when creating the volumes, or you can change
the Read RAM Cache feature later. If you want to enable the caching feature, ensure
that the feature is also enabled in the backend of the system, for the corresponding
Storage Pool and SDSs. For more information, see "Changing Read RAM Cache
volume settings".
