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.
If a RAID Group is configured with SSD, the Eco-mode cannot be set.
Eco-mode cannot be set for the RAID Group configured with a system
disk.
Eco-mode cannot be set for the RAID Group registered as a REC Disk
Buffer.
Eco-mode cannot be set for the RAID Group registered in Thin
Provisioning Pool (TPP) using the [Set RAID Group-Eco-mode]
function. Set the Eco-mode for TPP using the [Set Thin Provisioning
Pool-Eco-mode] menu.
Eco-mode cannot be set for the RAID Group registered in a Thin
Provisioning Pool.
When the [External] management (disk motor management by the
Storage Foundation Software ETERNUS SF(*1)) is selected, it is
possible to change to the RAID Group-Eco-mode schedule. However,
when the RAID Group-Eco-mode schedule is selected, it is impossible
to change to the [External] management.

When Resource Domains are registered in the ETERNUS DX400/
DX8000 series, RAID Groups to which the Eco-mode can be set differ
depending on the current user account.
- When logged on using a Total Administrator account, the Eco-mode
can be set for all the RAID Groups that are assigned to Resource
Domains.
- When logged on using a Resource Domain Administrator account,
the Eco-mode can be set only for the RAID Groups that are assigned
to the relevant Resource Domain and the Shared Resource.
Eco-mode for the entire device is specified on the [Set Common Eco-
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".
Set the Eco-mode schedule on the [Set Eco-mode Schedule] menu.
