• Before applying ECO mode for TPPs, use the procedure in "11.2.8.1 Modify ECO Mode General Setting"
(page 869) to enable the ECO mode setting for the ETERNUS DX Disk storage system.
• Set the ECO mode schedule using the procedure in "11.2.8.4 Modify ECO Mode Schedule" (page 876)
.
• This function cannot be used under the following conditions:
- No volumes are created
- Configured by SSDs
• When using ECO mode, make sure to set the time/date correctly. If the time/date of the ETERNUS DX Disk
storage system is wrong, processes used for stopping and starting the disk motor cannot be performed
per the ECO mode schedule.
• If any of the following conditions occur during the ECO mode scheduled time, the disk will be started even
when the disk motor is inactive. Note that the ECO mode schedule will be re-enabled when the following
conditions have finished.
- When the target TPP status is not " Available"
- When performing functions that change the TPP or the volume configuration
- When performing rebuild or copyback in the RAID groups that configure the target TPP
- When formatting is being performed in the TPP
- When RAID migration is being performed in the volumes registered in the TPP
- When Advanced Copy is being performed in the volume registered in the TPP (copy session status is
not "Suspend" or "Tracking")
- During maintenance
- When performing disk diagnosis, TPP diagnosis (diagnosing the RAID groups that configure the TPP),
or when exporting G-List
- When a module error related to the access paths of the Controller Modules and drives is detected
• When the ECO mode is set to TPP, the same ECO Mode schedule is set 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
specified for all the selected TPPs.
