Controller Object Commands

/cx show spinup

This feature only applies to 9000 series controllers.

This command reports the number of concurrent disks that will spin up when the system is powered on, after waiting for the number of seconds specified with the set stagger command.

Example:

//localhost> /c0 show spinup /c0 Disk Spinup Policy = 1

/cx show stagger

This feature only applies to 9000 series controllers.

This command reports the time delay between each group of spinups at the power on.

Example:

//localhost> /c0 show stagger

/c0 Spinup Stagger Time Policy (sec) = 2

/cx show ondegrade

This feature only applies to 9500S controllers.

This command reports the cache policy for degraded units. If the ondegrade policy is “Follow Unit Policy,” a unit cache policy stays the same when the unit becomes degraded. If the ondegrade policy is off, a unit cache policy will be forced to “off” when the unit becomes degraded.

Example:

//localhost> /c0 show ondegrade

/c0 Cache on Degraded Policy = Follow Unit Policy

/cx show autocarve

This feature only applies to 9000 series controllers.

This command reports the Auto-Carve policy. If the policy is on, all newly created or migrated units larger than the carvesize will be automatically carved into multiples of carvesize volumes plus one remainder volume. Each volume can be treated as an individual drive with its own file system. The default carvesize is 2TB. For more information see, “/cx show carvesize”, below.
