Configuring drive spin down for available disks and global spares
The drive spin down (DSD) feature monitors disk activity within system enclosures and spins down inactive
disks. You can enable or disable DSD for available disks and global spares, and set the period of
inactivity after which the vdisk's disks and dedicated spares automatically spin down.
To configure a time period to suspend and resume DSD for all disks, see
disks
on page 48. To configure DSD for a vdisk, see
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.
To configure DSD for available disks and global spares
1.
In the Configuration View panel, right-click the local system and select Configuration > Advanced
Settings > Disk.
2.
Set the options:
• Either select (enable) or clear (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), which is the period of inactivity after which available disks
and global spares automatically spin down, from 1–360 minutes. If DSD is enabled and no delay
value is set, the default is 15 minutes. The value 0 disables DSD.

Scheduling drive spin down for all disks
For all 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 a vdisk, see
for available disks and global spares, see
spares
on page 48.
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.
To schedule DSD for all disks
1.
In the Configuration View panel, right-click the local system and select Configuration > Advanced
Settings > Disk.
2.
Set the options:
• Select the Drive Spin Down Suspend Period option.
• Set a time to suspend and a time to resume DSD. 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.

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