Set Rec-Buffer - Fujitsu ETERNUS DX80 S2 Cli User's Manual

Chapter 4 Function/System Settings and Display
4.2 Advanced Copy Management > set rec-buffer

set rec-buffer

This command sets up REC buffers for use by the REC Asynchronous Consistency function. Up to 4 REC buffers
for the ETERNUS DX90 S2 and up to 8 REC buffers for the ETERNUS DX410 S2/DX440 S2 and ETERNUS DX8100
S2/DX8700 S2 can be set. When an REC buffer is newly defined, all the parameters must be specified. When an
existing REC buffer is changed, only the needed parameters may be specified.
The size of each REC buffer can be selected as follows:
• ETERNUS DX90 S2: 128MB, 256MB, and 512MB
• ETERNUS DX410 S2/DX440 S2: 128MB, 256MB, 512MB, 1024MB, and 2048MB
• ETERNUS DX8100 S2/DX8700 S2: 128MB, 256MB, 512MB, 1024MB, and 2048MB
The maximum value of the total REC buffer transfer size is shown below. Note that the upper limit value
depends on the memory size that is installed in the controllers.
• ETERNUS DX90 S2: 512MB
• ETERNUS DX410 S2: 4096MB
• ETERNUS DX440 S2: 8192MB
• ETERNUS DX8100 S2/DX8700 S2: 8192MB
Receive and Send REC buffers must both be independently defined if the REC buffer is to be used bi-
directionally.

■ Parameter
-partition
storage_system_box_id
]
This parameter specifies the REC buffer partition number. This can also be called the group
number. This number starts from 0. Only one number can be specified at a time. The selectable
range is as follows:
ETERNUS DX90 S2: 0 to 3
ETERNUS ETERNUS DX410 S2/DX440 S2: 0 to 7
ETERNUS ETERNUS DX8100 S2/DX8700 S2: 0 to 7
When the specified number is already used, existing set values are overwritten.
