/cx/ux set rapidrecovery all|rebuild|disable [quiet]
This command only applies to 9000 series controllers, models SE and SA, and only for redundant units. Firmware 9.5.1 or later is required.
This command sets the Rapid RAID Recovery policy for the specified unit.
Rapid Raid Recovery can speed up the rebuild process, and it can speed up initialize and verify tasks that may occur in response to an unclean system shutdown. Setting this option to all applies this policy to both these situations. Setting it to rebuild applies it only to rebuild tasks. If the policy is set to disable, then none of the tasks will be sped up.
There is some system overhead from setting rapidrecovery to all. If you have a BBU, you can set rapid recovery to rebuild, as a BBU provides protection against data loss in the event of an unclean shutdown.
Once this attribute is set, the policy remains in effect unless it is changed or disabled for the unit. Note: Once disabled, this setting cannot be changed for the unit at a later time.
The quiet option is provided for scripting purposes, and is applicable only to the disable option. (/cx/ux set rapidrecovery=disable quiet)
 
Note: When upgrading to 9.5.1, redundant units created using firmware verisons prior to 9.5.1 are assigned a Rapid Recovery Policy of disable, which cannot be changed.
Example:
 //localhost> /c0/u0 set rapidrecovery=all
 Setting Rapid RAID Recovery policy on /c1/u0 to [all] ... Done.
