Assign Eco-mode Schedule (Thin Provisioning Pool)

Overview

This function assigns the Eco-mode schedule to the Thin Provisioning Pools (TPPs) 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 TPP 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
Enable Disable
Drive power Drive motor
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.
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
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 TPPs Drive power is on Drive motors are always stopped
*1  :  If the TPP 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 RAID group status in the TPP is not "Available"

    • Functions that change the TPP or the volume configuration is being performed

    • Rebuild or copyback is being performed in the RAID groups that configure the target TPP

    • Formatting is being performed in the TPP

    • Formatting is being performed in the volumes registered in the TPP

    • RAID migration is being performed in the volumes registered in the TPP

    • Advanced Copy is being performed in the volume registered in the TPP (copy session status is not "Suspend" or the phase is not "Tracking")

    • NAS system volumes exist in the TPP

    • During maintenance

    • Disk diagnosis or RAID group diagnosis (diagnosing the RAID groups that configure the TPP) 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

  • 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 TPPs, 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.

  • When the Eco-mode is set to TPP, the same Eco-mode schedule is set for all the RAID groups configuring the TPP.
