• LCU manages the number of Logical Volumes and IOA Mapping
for each CA Port. The number of Logical Volumes managed by
one LCU is 256. The Logical Volumes assigned to the IOA
Mapping managed by an LCU cannot be used by another LCU.
(Example 1)
When creating [IOA: 0x01 – Logical Volume# 0x0001] in the IOA
Mapping information of OCLINK Port#0 LCU# 0x00
- [Logical Volume# 0x0001] cannot be allocated anywhere
except [LCU# 0x00] for OCLINK and FCLINK registered in the
ETERNUS DX8100/DX8400/DX8700.
- In the case of OCLINK or FCLINK other than OCLINK Port#0,
[Logical Volume# 0x0001] can be assigned to any IOA within
[LCU# 0x00] except for [IOA: 0x01].
- In the case of OCLINK or FCLINK other than OCLINK Port#0,
[Logical Volume# 0x0001] is not required to be allocated to
any IOA within [LCU# 0x00].
(Example 2)
When 250 Logical Volumes are mapped in the IOA Mapping information
of OCLINK Port#0 LCU#0x00.
Only six Logical Volumes can be mapped in the LCU#0x00 of other CA
Port.
• If using in manual operation (direct input), you do not need to
