/cx set autocarve=on|off
This feature only applies to 9000 series SX/SE/SA model controllers.
This command allows you to set the auto-carve policy to on or off. By default, autocarve is off.
When the auto-carve policy is set to on, any unit larger than the carvesize is created or migrated into one or more carvesize volumes and a remaining volume. Each volume can then be treated as an individual disk with its own file system. The default carvesize is 2 TB.
This feature is useful for operating systems limited to 2 TB file systems.
For example, using the 2 TB default carvesize, a 3 TB unit will be configured into one 2 TB volume and one 1 TB volume. A 5 TB unit will be configured into two 2 TB volumes and one 1 TB volume.
When auto-carve policy is set to off, all new units are created as a single large volume. If the operating system can only recognize up to 2 TBs, space over 2 TB will not be available.
Example:
//localhost> /c0 set autocarve=on
 Setting Auto-Carving Policy on /c0 to on ... Done.
