Chapter 2. CLI Syntax Reference

/cx set stagger=nn

This command is only for 9000 series controllers.

This command allows you to set a controller-based Disk Spinup Stagger Time Policy that specifies the delay between spin-ups. The value must be a positive integer between 0 to 60 seconds. This policy, in conjunction with Disk Spinup Policy, specifies how the controller should spin up disks at boot time. The default is 6 seconds.

/cx set autocarve=onoff

This command is only for 9000 series 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 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.

/cx set carvesize=[1024..2048]

This command is only for 9000 series controllers.

This command allows you to set the carve size in GB. This feature works together with autocarve. See “/cx set autocarve=onoff” above for details.

Example:

//localhost> /c0 set carvesize=2000

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