LCU is a virtual FCU (File Control Unit) that is defined in the Mainframe disk subsystem. LCU
Setting enables the mainframe host to recognize
ETERNUS DX8100/DX8400/DX8700 which
has more than 256 Logical Volumes as multiple logical subsystems. In the
ETERNUS DX8100/
DX8400/DX8700
, up to 32 LCUs (for ETERNUS DX8400/DX8700) are defined, and up to 256
Logical Volumes can reside in each LCU. A Unique SSID (Subsystem ID) is assigned to each
LCU.
LCU is set only when the host and the ETERNUS DX8100/DX8400/DX8700 are connected via
OCLINK or FCLINK.
