Logical Volume Images; Logical Units; Mainframe Operations - Hitachi G1000 Hardware Manual

The storage system supports the following control unit (CU) emulation types:
• 3990-6, 3990 6E
• 2107
The mainframe data management features of the storage system may have
restrictions on CU image compatibility.
For more information on CU image support, see the Mainframe Host
Attachment and Operations Guide, or contact your Hitachi Data Systems
account team.

Logical volume images

The VSP G1000, VSP G1500, and VSP F1500 support the following Mainframe
LVI types:
• 3390-3, -3R, -9, L, and -M.
• The 3390-3 and 3390-3R LVIs cannot be intermixed in the same storage
The LVI configuration of the storage system depends on the RAID
implementation and physical data drive capacities. The LDEVs are accessed
using a combination of logical disk controller number (00), CU number (00-
FE), and device number (00-FF). All control unit images can support an
installed LVI range of 00 to FF.
For maximum flexibility in LVI configuration, the storage system provides the
Virtual LVI feature. Using Virtual LVI, users can configure multiple LVIs under
a single LDEV. For further information on Virtual LVI, see the Provisioning
Guide for Mainframe Systems.

Logical units

The storage system is configured with OPEN-V logical unit types. The OPEN-V
logical unit can vary in size from 48.1 MB to 4 TB. For information about
other logical unit types, for example, OPEN-9, contact Hitachi Data Systems
support.
For maximum flexibility in LU configuration, the storage system provides the
Virtual LUN feature. Using Virtual LUN, users can configure multiple LUs
under a single LDEV. For further information on Virtual LUN, see the
Provisioning Guide for Open Systems.
