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 2TB 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.

set carvesize=[1024..2048]

This feature only applies to 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.

Example:

//localhost> /c0 set carvesize=2000

Setting Auto-Carving Size on /c0 to 2000 GB ... Done.

set autorebuild=on|off

This feature only applies to 9000 series SX/SE/SA model controllers.

This command turns the Auto-Rebuild policy on or off. By default,

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.

2. Smallest usable unconfigured (available) drive.

3. Smallest usable failed drive.

Enabling Auto-Rebuild allows you to add a drive to the controller and have it

be available for a rebuild as soon as you tell the controller to rescan, without

Note: Failed drives can be drives that have mechanically failed, or they can be

drives that have been disconnected from the controller long enough to cause a

drive timeout error and for the controller to classify them as failed.
