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
1 Click [Create Schedule] in [Action].
2 Specify the schedule name, and click the [Add Event] button.
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.
To apply the created ECO Mode schedule to RAID groups, refer to the procedure in "6.2.7 Assign ECO Mode
Schedule (RAID Group)" (page 192).
To apply the created ECO Mode schedule to each Thin Provisioning Pool, refer to the procedure in "7.2.9
