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.
/c x set carvesize=[1024..32768]
This feature only applies to 9750 model controllers and 9000 series SX/SE/
SA model controllers.
This command allows you to set the carve size in GB. This feature works
together with autocarve. See “/cx set autocarve=on|off” above for details.
Note that for some operating systems are limited to 2 TB. (For details, see
“Support for Over 2 Terabytes” on page 10.)
Example:
//localhost> /c0 set carvesize=2000
Setting Auto-Carving Size on /c0 to 2000 GB ... Done.
/c x set autorebuild=on|off
This feature only applies to 9750 model controllers and 9000 series SX/SE/
SA model controllers.

autorebuild is on.
If the policy is on the firmware will select drives to use for rebuilding a
degraded unit using the following priority order.
1. Smallest usable spare.
