•
The ETERNUS DX200F does not support this function.
•
This function cannot be used for TPPs under the following conditions:
-
No volumes are created
-
Configured by SSDs or SSD SEDs
•
When using Eco-mode, make sure to set the time/date correctly. If the time/date of the ETERNUS DX S3
series is wrong, processes used for stopping and starting the drive motor cannot be performed per the
Eco-mode schedule.
•
When the "External" (drive motor management by the Storage Foundation Software ETERNUS SF) is
selected, it can be changed to the Eco-mode schedule. But when the Eco-mode schedule is selected, it
cannot be changed to "External".
•
If any of the following conditions occur during the Eco-mode scheduled time, the drive will be started
even when the drive motor is inactive. The Eco-mode schedule is re-enabled when the conditions listed
have finished. (*1)
-
The RAID group status in the TPP is not "
Available"
-
Functions that change the TPP or the volume configuration is being performed
-
Rebuild or copyback is being performed in the RAID groups that configure the target TPP
-
Formatting is being performed in the TPP
-
Formatting is being performed in the volumes registered in the TPP
-
RAID migration is being performed in the volumes registered in the TPP
-
Advanced Copy is being performed in the volume registered in the TPP (copy session status is not
"Suspend" or the phase is not "Tracking")
-
NAS system volumes exist in the TPP
-
ODX Buffer volumes exist in the TPP
-
During maintenance
-
Disk diagnosis or RAID group diagnosis (diagnosing the RAID groups that configure the TPP) is being
performed, or G-List is being exported
-
A module error related to the access paths of the controller modules and drive is detected
•
If the server OS or software periodically accesses the ETERNUS DX, the drive motor may not stop even
when the Eco-mode is enabled.(*1)
*1:
This not only affects the motor stoppage, but includes the cutting of the drives power as well.
•
Before applying Eco-mode for TPPs, use the procedure in
"1.6.1 Modify Eco-mode General Setting" (page
to enable the Eco-mode setting for the ETERNUS DX S3 series.
•
Set the Eco-mode schedule using the procedure in
"1.6.2 Create Eco-mode Schedule" (page 76)
•
When the Eco-mode is set to TPP, the same Eco-mode schedule is assigned for all the RAID groups
configuring the TPP.
•
When selecting multiple TPPs as the target of the Eco-mode, the same Eco-mode schedule can be
assigned for all the selected TPPs.
