About Volumes on HDS Storage Systems
Volumes from single LDEVs are shown as LDEV:0 on HDS storage systems. When volumes made
up of multiple LDEVs are first created, they are not mapped to a target port on the storage system.
The software remembers these LDEVs constitute a single volume, but it does not make changes to the
storage system until the volume is mapped to a port. As a result, they are referred to as Groups, for
example:
Group:0(LDEV:0, LDEV:1)
where 0 in Group:0 is the volume identifier and LDEV:0 and LDEV:1 are the LDEVs that make up
this volume.
After you create a storage volume on an HDS storage system, you must map the volume to a target
port on the storage system. You can map the volume to the target port by using the storage system
Provisioning tool. In the tool, click Step 3, LUNs.
Once the volume is mapped, it is displayed as a logical unit size expansion (LUSE), as shown
below:
LUSE:0(LDEV:0, LDEV:1)
