•Occurrence of any of the following on an Eco-mode RAID group (disk
drive motors stopped) will cause the disk drive motors to be started.
Eco-mode will be re-enabled when the interrupting process is resolved
(finished, etc.):
-Volume configuration is being changed (RAID groups being deleted
or registered, volumes being deleted or formatted, etc.)
-Host access is requested
-Advanced Copy (EC/REC) is started or resumed
-Snap Data Pool Volume is registered
•If the Snap Data Pool Volume is set for the RAID Group, the Eco-mode
schedule can be specified, but the Eco-mode is disabled (disk motors
are not activated nor stopped). When the Open Volumes, Snap Data
Volumes, and/or Snap Data Pool Volumes are registered in the RAID
Group with the Eco-mode schedule setting, the Eco-mode is enabled
after deleting all the Snap Data Pool Volumes.

disk.
•Eco-mode cannot be set for the RAID Group registered as a REC Disk
Buffer.

can be set for all the RAID Groups that are assigned to Resource
Domains.

the Eco-mode can be set only for the RAID Groups that are assigned
to the relevant Resource Domain and the Shared Resource.

mode] menu. Eco-mode for the RAID group is enabled when the Eco-
mode for the entire device is enabled and the Eco-mode for the RAID
group is "ON".
