The Create Devices wizard
Use the Create Devices wizard to create the following types of devices:
● RAID-1
Additionally, you can use the 1:1 Mapping of extents to devices option in the wizard to create a device for each selected
extent. While creating these devices, you have the option of creating a virtual volume on the device. Supported RAID types
provides more information about the RAID types. For each type of RAID, you can select a maximum of 64 extents.
To create a device using different device types, use the CLI. The CLI Guide for metro node provides more information.
RAID-1 devices
When creating a RAID-1 device, you must select a source and target extent in order to synchronize the data between extents.
RAID-1 creates a device that mirrors I/O from the source to the target extent. For RAID-1 devices, you must select extents from
different storage volumes. Once you select one extent from a storage volume, all other extents from that storage volume are
removed from your selection options. You can select any number of source and target extents to create a RAID-1 device. When
you view the device map, the extents display as children of the device.
1:1 Mapping of Extents to Devices
One to one mapping creates a device for each selected extent. The device is the total capacity of each selected extent. Note
that 1:1 mapping creates a RAID-0 device a with stripe depth of 1.
