希捷powerchoice磁盘休眠功能配置方法

本篇关于希捷磁盘休眠的配置方法

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

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

是卸载磁头到硬盘斜坡

官方给出的功耗数据

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

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

./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

后面的单位为100ms

./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

[root@node120 ~]# ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp --showEPCSettings

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

./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp  --checkPowerMode;
[root@node120 ~]# ./SeaChest_PowerControl_1100_11923_64 -d /dev/sdp  --checkPowerMode;

/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

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

Device is in the PM0: Active state or PM1: Idle State

注意，这个命令

./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
