This section explains how to create a REC Disk Buffer.
Procedure
1 Click [Create REC Disk Buffer] under the Advanced Copy Settings in the
[Settings] menu.
→ The [Create REC Disk Buffer (Set Creating Information)] screen appears.
• A single REC Disk Buffer is configured with a single RAID Group. When
the REC Disk Buffer creation process is compl e t e , t h e R E C D i s k B u f f e r
will be formatted automatically. Refer to the [RAID Group List] function
for format progress.
• A REC Disk Buffer can be created regardless of the existing REC
Buffers.
• A REC Disk Buffer is only used as a backup destina tion of a REC Bu ffer
(Send). Note that it is not used for a REC Buffer (Receive).
• A REC Disk Buffer is assigned to the REC Buffe r u s i n g t h e [ S e t R E C
Buffer] function. Note the following conditions when assigning REC Disk
Buffers:
- A single REC Disk Buffer cannot be assigned to multiple REC
Buffers.
- One, two, or four (one or two for ETERNUS DX410) REC Disk
Buffers can be assigned to a single REC Buffer. When assigning
multiple REC Disk Buffers to a REC Buffer, RAID levels
(RAID1+0(2+2) or RAID1+0(4+4)), disk type (Fibre Channel disk
drive or SSD), encryption status (ON or OFF), and capacity must be
matched in a REC Buffer. If REC Disk Buffers of different capacities
exist in a single REC Buffer, all REC Disk Buffers that are registered
in that REC Buffer have the same capacity as the smallest REC Disk
Buffer.
If the ETERNUS DX400/DX8000 series does not satisfy the
conditions for creating REC Disk Buffers, the [Suppress Function]
screen appears. Click the [OK] button to return to the [Menu] screen.
For more details on the required conditions, refer to "Conditions for
Creating REC Disk Buffers" (page 483).
