When Using SnapOPC+ (SDVs and SDPVs)
The following section describes the series of environment settings when using SnapOPC+ (SDVs and SDPVs).
Not only can new RAID groups be created, adding or changing volumes that are registered in existing RAID
groups can also be performed.
1 Create RAID Group
Create a RAID group (a group of drives that configures the RAID in the ETERNUS DX).
Refer to: "RAID Group Creation" (page 109)
2 Create Volume
Create a volume (drive area in the RAID group). A volume is a structural unit of RAID that can be
recognized from the server. Select "SDV" or "SDPV" for "Type".
Refer to: "Generation Management Volume (SDV) Creation" (page 117) and "Copy Data Destination
Volume (SDPV) Creation" (page 118)
Generation Management Volume (SDV) Creation
Create a generation management volume in the backup RAID group.
Create SDV for seven generations (as a backup area for seven days a week) in the backup RAID group "RG1"
created in "RAID Group Creation" (page 109).
