本文链接地址: smartctl获取raid卡下intel ssd寿命
我们在线上用了大量的Intel ssd盘，总所周知的是ssd盘是有寿命的，在实际的使用中能够监控ssd盘是非常有帮助的。
我们通常是在raid卡下用intel ssd盘做10level的阵列，通常的工具很难读出它的寿命信息等。 经过intel和社区的努力，对intel ssd的寿命读取代码集成到了smartctl中去了， 这下我们方便了。
先交代下我们的环境：
硬件和操作系统：
System | Huawei Technologies Co., Ltd.; Tecal RH2285; vV100R001 (Main Server Chassis)
Release | Red Hat Enterprise Linux Server release 5.4 (Tikanga)
Kernel | 2.6.18-164.el5
Architecture | CPU = 64-bit, OS = 64-bit
raid卡控制器：

我们再来演示下如何使用：
STEP1： 因为我们用的是LSI的raid卡，需要先安装raid卡的工具程序：
首先去lsi官网去拉个megacli-2.00.11-2.x86_64.rpm
$ sudo rpm -i megacli-2.00.11-2.x86_64.rpm #一定要root权限运行 $ sudo /opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -aALL Adapter #0 Number of Virtual Disks: 2 Virtual Drive: 0 (Target Id: 0) Name : RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 Size : 278.464 GB State : Optimal Strip Size : 64 KB Number Of Drives : 2 Span Depth : 1 Default Cache Policy: WriteBack, ReadAheadNone, Direct, Write Cache OK if Bad BBU Current Cache Policy: WriteBack, ReadAheadNone, Direct, Write Cache OK if Bad BBU Access Policy : Read/Write Disk Cache Policy : Enabled Encryption Type : None Number of Spans: 1 Span: 0 - Number of PDs: 2 PD: 0 Information Enclosure Device ID: 12 Slot Number: 0 Enclosure position: 0 Device Id: 13 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SAS Raw Size: 279.396 GB [0x22ecb25c Sectors] Non Coerced Size: 278.896 GB [0x22dcb25c Sectors] Coerced Size: 278.464 GB [0x22cee000 Sectors] Firmware state: Online, Spun Up SAS Address(0): 0x5000c5002bdd95fd SAS Address(1): 0x0 Connected Port Number: 4(path0) Inquiry Data: SEAGATE ST3300657SS 00066SJ017HA FDE Capable: Not Capable FDE Enable: Disable Secured: Unsecured Locked: Unlocked Needs EKM Attention: No Foreign State: None Device Speed: 6.0Gb/s Link Speed: 3.0Gb/s Media Type: Hard Disk Device Drive Temperature :39C (102.20 F) ...

注意上面的：Device Id: xxx, 下面要用的，说明raid正常读取信息了。
STEP2：
我们还需要下载较新的smartmontools 5.39或者5.40 来使用：
http://sourceforge.net/projects/smartmontools/files/smartmontools/
编译安装后我们就有了smarctl.

推荐读物：
我们dba写的有更详细的对intel ssd信息的解释，看这里!
另外我还写了个脚本自动获取各个intel ssd的脚本片段：
OPT_l="${OPT_l:-/tmp/intel_ssd_life}"; export OPT_l;
OPT_s="${OPT_s:-60}"; export OPT_s;
export PATH="${PATH}:/usr/local/bin:/usr/bin:/bin:/usr/libexec"
export PATH="${PATH}:/usr/local/sbin:/usr/sbin:/sbin"
export PATH="${PATH}:/opt/MegaRAID/MegaCli/"
PID=$$
date +"TS %s.%N" > ${OPT_l}
while true; do
if MegaCli64 -PDList -aALL >/tmp/isl 2>/dev/null; then
for dev in $(awk '/Device Id/{print $3}' /tmp/isl); do
idev="$(sed -e '/./{H;$!d;}' -e "x;/Device Id: ${dev}/!d;" /tmp/isl\
|awk '
/Device Id/ {d=$3}
/Inquiry Data/ {if ($0 ~ /INTEL/) {printf("%d\n", d)}}
')"
if [ -n "${idev}" ]; then
(echo -n "Device Id[${idev}]:" && smartctl -a -d megaraid,${idev} /dev/sda |grep "Media_Wearout_Indicator") >> ${OPT_l} 2>/dev/null
fi
done
date +"TS %s.%N" >> ${OPT_l}
if ! ps -p ${PID} >/dev/null 2>&1; then
break;
fi
fi
sleep ${OPT_s}
done &
echo "running in background, see result please type: cat /tmp/intel_ssd_life"
# do something issue ios here
# ...
# end
结果类似以下：
$cat /tmp/intel_ssd_life

用的上的同学自己再修改下要收集的信息点的代码。

貌似现在用dmesg也可以看到ssd盘的device id
# dmesg |grep -i “INTEL SSD”
scsi 0:0:12:0: Direct-Access ATA INTEL SSDSC2CW24 400i PQ: 0 ANSI: 5
scsi 0:0:13:0: Direct-Access ATA INTEL SSDSC2CW24 400i PQ: 0 ANSI: 5

能获取到就可以。
还有一事请教
#smartctl -a -d sat+megaraid,12 -d /dev/sda
我想把/dev/sda换成virtual id，这个您知道怎么写吗？
