11.2.6.2 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 device.
• 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].
• 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" (page 131)
.
• To apply the created ECO Mode schedule to each Thin Provisioning
Pool, refer to the procedure in "7.2.8 Assign ECO Mode Schedule"
