hd-idle -a /dev/sda1 -i 10
-i 后面10为10秒后休眠
-a 后面为硬盘名
解释：
| -a <name> | Set (partial) device name of disks for subsequent idle-time parameters (-i). This parameter is optional in the sense that there‘s a default entry for all [SCSI] disks which are not named otherwise by using this parameter. |
| -i <idle_time> | Idle time in seconds for the currently named disk(s) (-a <name>) or for all disks. |
| -l <logfile> | Name of logfile (written only after a disk has spun up). Please note that this option might cause the disk which holds the logfile to spin up just because another disk had some activity. This option should not be used on systems with more than one disk except for tuning purposes. On single-disk systems, this option should not cause any additional spinups. |
| -t <disk> | Spin-down the specified disk immediately and exit. Use only the disk name (e.g. sda) without /dev/ prefix |
| -d | Debug mode. This will prevent hd-idle from becoming a daemon and print debugging info to stdout/stderr |
| -h | Print brief usage information |
Users of hd-idle have asked for means to set idle-time parameters for individual disks. This makes a lot of sense, not only because some [SCSI] disks may not react well to being stopped. Originally, hd-idle had one idle time for all disks. The parameter "-a" can now be used to set a filter on the disk‘s device name (omit /dev/) for subsequent idle-time settings.
Example:
hd-idle -i 0 -a sda -i 300 -a sdb -i 1200
This example sets the default idle time to 0 (meaning hd-idle will never try to spin down a disk), then sets explicit idle times for disks which have the string "sda" or "sdb" in their device name.
