我正在尝试暂停两个设置为 RAID1 并带有逻辑卷的 8TB 驱动器。
这些磁盘是相同的，因此我在这里仅显示一个磁盘的输出，但和的输出 (bar Unique ID)相同。/dev/sdc/dev/sdd

我读到上面的内容是我可以开车......
- 支持电源管理（APM）。
- 有密码但未启用，驱动器也未锁定或冻结，并且安全计数尚未过期。
hdparm -B所以我尝试使用和来设置降速hdparm -S。
hdparm -B
# hdparm -B /dev/sdc
/dev/sdc:
APM_level = not supported
令人惊讶的是，给出的信息表明它支持Power Management feature set，或者它Device-initiated interface power management与此处相关但不受此驱动器支持？
# hdparm -B 127 /dev/sdc
/dev/sdc:
setting Advanced Power Management level to 0x7f (127)
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 04 51 40 7f 21 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
APM_level = not supported
找一个线建议SG_IO: bad/missing sense data可以通过暂停来纠正错误，但不能在这里骰子。
hdparm -S
# hdparm -S 127 /dev/sd{c,d}
/dev/sdc:
setting standby to 127 (10 minutes + 35 seconds)
看起来很有希望，但在检查...
# hdparm -S /dev/sd{c,d}
-S: bad/missing standby-interval value (0..255)
其不保留。有关的线。
问题
鉴于上述...
如何解决
SG_IO: bad/missing sense data, sb[]？如何正确挂起空闲磁盘？
想要这样做的主要原因有两个，首先驱动器非常吵，其次它们实际上并没有定期使用，因为保持音乐/工作只是定期使用。
