准备设置的软件 下载地址
https://raw.githubusercontent.com/Seagate/ToolBin/master/SeaChest/PowerControl/v1.10.0/Linux/SeaChest_PowerControl_1100_11923_64
或者通过
http://support.seagate.com/seachest/SeaChestUtilities.zip
下载后解压拿到二进制文件
注意版本尽量用这个版本，不同的版本命令不同，可以有的重要命令不支持，所以限定这个版本即可
磁盘休眠相关命令 默认磁盘开启的是idle_a的节能模式，这个模式实际上不省电
服务器的操作是禁用了一些内部服务，减少处理器和通道功耗，磁盘还是全速转动
idle b 模式
官方给出的功耗数据
1 https://www.seagate.com/www-content/product-content/enterprise-hdd-fam/enterprise-capacity-3-5-hdd/enterprise-capacity-3-5-hdd/en-us/docs/100791104c.pdf
1 2 3 4 idle_A 4.36 idle_B 2.98 idle_C 2.34 Standby 0.80
考虑恢复时间和功耗的节省问题，我们选择idle_B
关闭AB模式，也就是关闭省电模式
1 2 ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --disableMode --changePower --powerMode idle_b ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --disableMode --changePower --powerMode idle_a
开启B模式的省电模式，并设置休眠时间为60s
1 2 ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --disableMode --changePower --powerMode idle_a ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --enableMode --changePower --powerMode idle_b --modeTimer 600
这个可以不管什么情况，都把A模式关闭了，否则同时设置的时候，会优先进入a模式
检查当前的省电设置情况
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 [root@node120 ~] ========================================================================================== SeaChest_PowerControl - Seagate drive utilities - NVMe Enabled Copyright (c) 2014-2019 Seagate Technology LLC and/or its Affiliates, All Rights Reserved SeaChest_PowerControl Version: 1.10.0-1_19_23 X86_64 Build Date: Jun 10 2019 Today: Mon Aug 24 10:51:36 2020 ========================================================================================== /dev/sg17 - ST10000NM0016-1TT101 - ZA2CRY9G - ATA . ===EPC Settings=== * = timer is enabled C column = Changeable S column = Saveable All times are in 100 milliseconds Name Current Timer Default Timer Saved Timer Recovery Time C S Idle A 0 *1 1 1 Y Y Idle B *10 *1200 *10 4 Y Y Idle C 0 6000 6000 50 Y Y Standby Z 0 9000 9000 120 Y Y
可以看到我的设置是1s的，这个是我方便测试看是否能进入到省电B模式设置的1s的，实际按照我们自己的设计是60s的
查询当前磁盘的省电状态的命令
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --checkPowerMode; [root@node120 ~] ========================================================================================== SeaChest_PowerControl - Seagate drive utilities - NVMe Enabled Copyright (c) 2014-2019 Seagate Technology LLC and/or its Affiliates, All Rights Reserved SeaChest_PowerControl Version: 1.10.0-1_19_23 X86_64 Build Date: Jun 10 2019 Today: Mon Aug 24 10:54:49 2020 ========================================================================================== /dev/sg17 - ST10000NM0016-1TT101 - ZA2CRY9G - ATA Device is in the PM1: Idle state and the device is in the Idle_b power condition [root@node120 ~] ========================================================================================== SeaChest_PowerControl - Seagate drive utilities - NVMe Enabled Copyright (c) 2014-2019 Seagate Technology LLC and/or its Affiliates, All Rights Reserved SeaChest_PowerControl Version: 1.10.0-1_19_23 X86_64 Build Date: Jun 10 2019 Today: Mon Aug 24 10:55:04 2020 ========================================================================================== /dev/sg17 - ST10000NM0016-1TT101 - ZA2CRY9G - ATA Device is in the PM0: Active state or PM1: Idle State
在省电模式的提示是
1 Device is in the PM1: Idle state and the device is in the Idle_b power condition
磁盘正在运行的模式是
1 Device is in the PM0: Active state or PM1: Idle State
注意，这个命令
1 ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --showEPCSettings
会唤醒磁盘也就是中断了省电模式，所以只有确定知晓会中断省电模式的时候才使用
管理平台不要频繁调用
如果需要检查当前模式就用上面的checkPowerMode命令，checkPowerMode命令不会唤醒磁盘，并且需要注意是否有本地的意外进程把磁盘省电模式中断了
