DD400 Series Restorer User Guide

     

clean start

 

          

Start the 

clean

 operation. With no options, the operation uses

 

          

the current parameters for the scheduled automatic cleaning.

 

          

The default and maximum that can be cleaned in one operation is

 

          

25%. A restorer that is at least 25% full and that is not busy with

 

          

other tasks takes from two to three hours for a single clean

 

          

operation. Administrative users only.

          

The 

clean

 operation can run for a given number of hours (

hrs

) or

 

          

until a given number of total gigabytes are free on the system

 

          

(

GB-free

), but cannot clean more than the maximum of 25% of

 

          

system capacity. You can set one or both options in one command.

 

          

Whichever limit the operation reaches first stops the operation.

          

The 

nowait

 option starts a 

clean

 operation with no warning

 

          

prompts. Use the option carefully.

          

Note that any operation that shuts down the restorer file system,

 

          

such as the 

filesys disable

 command, or that shuts down the

 

          

restorer, such as a system poweroff or reboot, also stops the 

clean

 

          

operation. The 

clean

 does not restart when the system and file

 

          

system restart. Either manually restart the 

clean

 or wait until the

 

          

next scheduled start.

     

clean status

 

          

Displays the status (active or not active) and progress of the

 

          

clean

 operation.

     

clean stop

 

          

Stop the 

clean

 operation. Administrative users only.

     

clean update-stats

 

          

Updates the "If 100% cleaned" numbers in the output from the

 

          filesys show space

 command by running most sections

 

          

of a full 

clean

 command. The update operation can take two to

 

          

three hours. Administrative users only.

     

destroy

 

          

Irrevocably deletes all data from and reinitializes the file system.

 

          

Data is not recoverable after a 

destroy

 operation. The 

and-zero

 

          

option writes zeros to the whole disk, which can take many hours.

 

          

Administrative users only.

     

disable

 

          

Turn off the restorer file system operations. Administrative users

 

          

only.
