Configuring drive spin down for a vdisk
The drive spin down (DSD) feature monitors disk activity within system enclosures and spins down inactive
disks. For a specific vdisk, you can enable or disable DSD 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 vdisks, see Scheduling drive spin down for
all disks on page 50. To configure DSD for available disks and global spares, see Configuring drive spin
down for available disks and global spares on page 49.
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 vdisk has started spinning down, the vdisk spins
up again.
To configure DSD for a vdisk
1. In the Configuration View panel, right-click a vdisk and select Configuration > Configure Vdisk Drive
Spin Down.
2. Set the options:
• Either select (enable) or clear (disable) the Enable Drive Spin Down option.
• Set the Drive Spin Down Delay (minutes), which is the period of inactivity after which the vdisk's
disks and dedicated spares automatically spin down, from 1–360 minutes. If DSD is enabled and
no delay value is set, the default is 15 minutes. A value of 0 disables DSD.
3. Click Apply. When processing is complete a success dialog appears.
4. Click OK.
