disk and is the same type: SATA SSD, SAS SSD, enterprise SAS, or midline SAS. If a spare or available compatible disk is already present,

the dynamic spares feature uses that disk to start the reconstruction and the replacement disk can be used for another purpose.

Change the dynamic spares setting

1. In the System topic, select Action > Advanced Settings > Disk.

2. Either select enable, or clear to disable the Dynamic Spare Capability option. The dynamic spares setting is enabled by default.

3. Click Apply. If you chose to disable dynamic spares, a confirmation panel appears. Click Apply to accept the changes or click Cancel.

Configuring drive spin down for available disks and global spares

For spinning disks, the drive spin down (DSD) feature monitors disk activity within system enclosures and spins down inactive disks to

conserve energy. You can enable or disable DSD for available spinning disks that are in non-ADAPT linear disk groups, for spinning disks

that are not in a virtual pool, and for global spares. You can also set the period of inactivity after which available disks and global spares

automatically spin down.

To configure a time period to suspend and resume DSD for all disks, see Scheduling drive spin down for available disks and global spares.

DSD affects disk operations as follows:

• Spun-down disks are not polled for SMART events.

• Operations requiring access to disks may be delayed while the disks are spinning back up.

Configure DSD for available disks and global spares

1. In the System topic, select Action > Advanced Settings > Disk.

2. Set the options:

• Either select to enable, or clear to disable the Available and Spare Drive Spin Down Capability option. If you are enabling DSD,

a warning prompt appears. To use DSD, click Yes. To leave DSD disabled, click No.

• Set the Drive Spin Down Delay (minutes) option, which is the period of inactivity after which available disks and global spares

automatically spin down, from 1 through 360 minutes. The default is 15 minutes.

3. Click Apply. When processing is complete a success dialog appears.

4. Click OK.

Scheduling drive spin down for available disks and global spares

For all spinning disks that are configured to use drive spin down (DSD), you can configure a time period to suspend and resume DSD so

that disks remain spun-up during hours of frequent activity.

To configure DSD for available disks and global spares, see Configuring drive spin down for available disks and global spares.

DSD affects disk operations as follows:

• Spun-down disks are not polled for SMART events.

• Operations requiring access to disks may be delayed while the disks are spinning back up.

• If a suspend period is configured and it starts while a disk has started spinning down, the disk spins up again.

Schedule DSD for all spinning disks

1. In the System topic, select Action > Advanced Settings > Disk.

2. Set the options:

• Select the Drive Spin Down Suspend Period option.

• Set the Time to Suspend and Time to Resume options. For each, enter hour and minutes values and select either AM, PM, or 24H

(24-hour clock).

• If you want the schedule to apply only Monday through Friday, select the Exclude Weekend Days from Suspend Period option.

3. Click Apply. When processing is complete a success dialog appears.

4. Click OK.
