Chapter 2. CLI Syntax Reference
/cx add type=<RaidType>
This command allows you to create a new unit on the specified controller. You specify type, disks, and optional stripe size. By default the host operating system will be informed of the new block device, write cache will be enabled, and a storsave policy of protect will be set. In case of RAID 50, you can also specify the layout of the unit by specifying the number of disks per disk group with the group attribute.
/cx is the controller name, for example /c0, /c1, and so forth.
type=RaidType specifies the type of RAID unit to be created. Possible unit types include raid0, raid1, raid5, raid6 (9650SE only), raid10, raid50, single, spare, and JBOD.
Example: type=raid5
When a new unit is created, it is automatically assigned a unique serial number. In addition, users can assign the unit a name.
Note: The unit’s serial number cannot be changed.
The following table shows supported types and controller models.
