Assign Eco-mode Schedule (RAID Group)

Overview

This function assigns the Eco-mode schedule to the RAID groups and sets the Eco-mode action.

There are three Eco-mode actions; "Drive power off", "Drive motor off", and "Drive always on". To enable the Eco-mode, assign the Eco-mode schedule to a RAID group and select "Drive power off" or "Drive motor off" as the Eco-mode action. When Eco-mode is enabled, the drives are activated during the scheduled event period. In the time periods outside the scheduled event, the drive status is changed according to the specified Eco-mode actions. Refer to "Drive Status When Eco-mode Action Is Configured" for details.

If the RAID group is accessed from the host while the drives are turned off or the drive motors are stopped, the drives are activated and can be accessed within 1 - 5 minutes.

Drive Status When Eco-mode Action Is Configured

Eco-mode Schedule Setting			Eco-mode General Settings
			Enabled		Disabled
			Drive power	Drive motor	Disabled
Eco-mode Action	Drive power off	During scheduled event term	Drive power is on	Drive motor is activated	Drive power is on or the drive motor runs regardless of the schedule.
	Drive power off	Times other than scheduled event term (*1)	Drive power is off	Drive motor is stopped
	Drive motor off	During scheduled event term	Drive power is on	Drive motor is activated
	Drive motor off	Times other than scheduled event term (*1)	Drive power is on	Drive motor is stopped
	Drive always on		Drive power is on	Drive motor is always activated
Eco-mode schedule is not assigned			Drive power is on	Drive motor is always activated
Drives not registered in the RAID groups			Drive power is on	Drive motors are always stopped

*1

:

If the RAID group is accessed, the drives are activated and can be accessed within 1 - 5 minutes.

Caution

When using Eco-mode, make sure to set the date/time correctly. If the time/date of the storage system is wrong, processes used for stopping and starting the drive motor cannot be performed per the Eco-mode schedule.
When "External" (drive motor management by FUJITSU ETERNUS SF Storage Management Software) 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 status of the RAID group is other than "Available"
- Functions that change the RAID group or the volume configuration are being performed
- Rebuild or copyback is being performed in the target RAID group
- LDE is being performed in the target RAID group
- Formatting is being performed in the volumes registered in the RAID group
- RAID migration is being performed in the volumes registered in the RAID group
- Advanced Copy is being performed in the volume registered in the RAID group (copy session status is not "Suspend" or the phase is not "Tracking")
- Encryption is being performed in the volumes registered in the RAID group
- During maintenance
- A disk diagnosis or a RAID group diagnosis is being performed or G-List is being exported
- A module error related to the access paths of the controller modules and drives is detected
Specify the same Eco-mode schedule for all of the RAID groups that configure a WSV. If a different Eco-mode schedule is specified, activation of a stopped drive is required to accept the host access, and the performance of the response may be reduced. RAID groups that configure a WSV can be checked in the [Volume Detail] screen ([Used RAID Group] tab). Refer to the [Volume] function for details.
If the server OS or software periodically accesses the storage system, the drive motor may not stop even when the Eco-mode is enabled. (*1)

*1 : This does not only affect the motor stoppage, but includes the cutting of the drives power as well.

Note

Before applying Eco-mode for RAID groups, use the [Modify Eco-mode General Setting] function to enable the Eco-mode setting for the storage system.
Set the Eco-mode schedule using the [Create Eco-mode Schedule] function.
To use Eco-mode for RAID groups registered in TPPs, assign the Eco-mode schedule to the TPPs. Refer to the [Assign Eco-mode Schedule (Thin Provisioning Pool)] function for details.
Dedicated Hot Spares are operated according to the Eco-mode schedule of the assigned RAID groups even if they are not included in the relevant RAID group.
Global Hot Spares are operated according to the Eco-mode schedule of the assigned RAID groups only when they are included in the RAID groups.
