11.2.8.2 Create ECO Mode Schedule
This function specifies the disk operating time (term for activating disk motor constantly) as an ECO mode
schedule.
• Up to 64 ECO mode schedules can be created for each storage system.
• Up to eight events can be specified for a single ECO mode schedule.
The procedure to create an ECO Mode schedule is as follows:
Procedure

• To perform schedule operations using this function, the ECO mode setting for the ETERNUS DX Disk
storage system must be enabled.
• Disk operation time varies depending on the ECO mode schedule settings and disk access. A disk is spun
up even if it is outside of disk operation time in the following conditions:
- If disk access occurs while the disk motor is stopped:
The disk is immediately spun up and can be accessed within 1 - 5 minutes.
- If a disk is activated more than a set amount of times in a day:
A state of increased access frequency is assumed and the ECO mode will cease stopping the disk
motor.

Schedule (RAID Group)" (page 192).
