本次由于需要搭建一套环境，但是所需硬件配置不足，需要进行统计采购。那么就需要得知服务器现有配置，所以这次会介绍些常用的命令和工具来查询硬件信息。其实也可以通过像DELL厂商的IDRAC控制台来获取这些信息，但是比较尴尬的是IBM在获取硬盘信息方面支持比较差，仅显示物理磁盘数量，能够获取的信息很少，这时就需要像storcli这种专业工具来收集。本章使用的命令查询需求比较单一，后续会在实际使用中慢慢补充上来。
一、查看服务器对应 IPMI 地址
[root@node-1 ~]# ipmitool lan print

二、查看网卡速率
[root@node-1 ~]# lspci | grep Ethernet #列出每个pci总线上的设备，通过grep过滤可得到网卡设备列表，这里看到总计8个网卡
06:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
06:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
06:00.2 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
06:00.3 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
11:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
11:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
20:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
20:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10)
[root@node-1 ~]# ethtool eth0 #查看单块网卡的详细信息
Settings for eth0:

三、查看内存信息
[root@node-1 ~]# cat /proc/meminfo
[root@node-1 ~]# dmidecode -t memory #此命令会列出每条内存的型号、频率等详细信息
Handle 0x000A, DMI type 17, 34 bytes

Asset Tag: Unknown

四、使用 storcli 查看服务器硬件基础信息
[root@node-1 ~]# rpm -ivh storcli-1.18.05-1.noarch.rpm #安装包请见文章末尾
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 show all #查询所有信息并show，在system overview下看到controller（缩写ctl）列数字就是controller号，得知node-1这台机器的controller号是0
System Overview :
===============
---------------------------------------------------------------------------
Ctl Model Ports PDs DGs DNOpt VDs VNOpt BBU sPR DS EHS ASOs Hlth
---------------------------------------------------------------------------
0 ServeRAIDM5110e 8 7 5 0 5 0 Opt On - Y 3 Opt
---------------------------------------------------------------------------
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 /c0 show #显示contrller0的raid卡的版本、功能、状态、以及raid卡下的物理磁、逻辑盘信息，这里我需要看物理磁盘的容量情况，可以在PD LIST部分找到
如果不需要其他信息，和我一样只需要知道物理磁盘信息的话可以使用如下命令
[root@node-1 ~]# /opt/MegaRAID/storcli/storcli64 /c0/eall/sall show
Controller = 0
Status = Success
Description = Show Drive Information Succeeded.
Drive Information :

252:6 18 Onln 4 557.861 GB SAS HDD N N 512B MBF2600RC U
-------------------------------------------------------------------------
五、不想安装 storcli 的情况下查看硬盘型号信息
[root@node-1 ~]# cat /proc/scsi/scsi|grep ‘Model:’ #node-1 是 IBM X3650 M4
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM Model: ServeRAID M5110e Rev: 3.34
Vendor: IBM SATA Model: DEVICE 81Y3682 Rev: D001
[root@node-5 ~]# cat /proc/scsi/scsi|grep ‘Model:’ #node-5 是 DELL R720，ST1000NM0023就是硬盘的型号
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0F
Vendor: SEAGATE Model: ST1000NM0023 Rev: GS0D
这种方式在硬盘做 raid 后不便于查看，例如下面查看我另一台服务器所看到到的，显示只有一块磁盘设备
[root@node-1 ~]# cat /proc/scsi/scsi|grep ‘Model:’
Vendor: DELL Model: PERC H710 Rev: 3.13
Vendor: TSSTcorp Model: DVD-ROM SN-108FB Rev: D150
接下来通过 lsblk 查看设备情况，发现这块盘总容量2.7T（我这里使用的盘是1T的SAS盘，可以倒推出是4块1T盘组成的raid5）正好对应上我在IDRAC界面中看到的四块物理磁盘
[root@node-1 ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 2.7T 0 disk
├─sda1 8:1 0 24M 0 part
├─sda2 8:2 0 200M 0 part
├─sda3 8:3 0 250M 0 part /boot
├─sda4 8:4 0 1.4T 0 part
│ ├─os-root 253:0 0 1.4T 0 lvm /
│ └─os-swap 253:1 0 32G 0 lvm [SWAP]
└─sda5 8:5 0 1.3T 0 part
└─mongo-mongodb 253:2 0 1.3T 0 lvm /var/lib/mongo
sr0 11:0 1 1024M 0 rom
storcli安装包各平台百度网盘链接地址（可在官网下载 https://www.broadcom.com/site-search?q=storcli）

提取码：pu7n
续：在检查过程中发现IBM服务器上有两块disk告警，联系维保需要提供FRU号，但是人又不在现场没办法拔盘拍照。所以需要通过storcli来查询盘对应FRU号。
六、查询硬盘FRU号
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 -PDList -aAll | grep FRU #如果想查看具体信息可以去掉过滤条件
IBM FRU/CRU: 42D0638
IBM FRU/CRU: 49Y2023
IBM FRU/CRU: 49Y2004
IBM FRU/CRU: 49Y2023
IBM FRU/CRU: 49Y2004
IBM FRU/CRU: 49Y2023
从上可以看到有两对重复的FRU号，怀疑可能是组成raid，那么就要通过storcli查看下硬盘raid情况
(1)查看逻辑磁盘
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/vall show #这里看到有5块逻辑磁盘，通过 /c0 show 命令查看物理磁盘发现有6块，继续向下查看硬盘 raid 情况。
Controller = 0
Status = Success
Description = None
Virtual Drives :

AWB=Always WriteBack|WT=WriteThrough|C=Cached IO|D=Direct IO|sCC=Scheduled
Check Consistency
(2)查看逻辑磁盘大小、raid结构
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/v0 show #可以看到 TYPE 为 RAID1，两块 600G 盘做的 RAID1，正好能够对上6块物理磁盘
Controller = 0
Status = Success
Description = None
Virtual Drives :
==============
---------------------------------------------------------------
DG/VD TYPE State Access Consist Cache Cac sCC Size Name
---------------------------------------------------------------
0/0 RAID1 Optl RW Yes RWBD - ON 557.861 GB

AWB=Always WriteBack|WT=WriteThrough|C=Cached IO|D=Direct IO|sCC=Scheduled
Check Consistency
[root@node-2 ~]# /opt/MegaRAID/storcli/storcli64 /c0/v1 show #可以看到 TYPE 为 RAID0
Controller = 0
Status = Success
Description = None
Virtual Drives :
==============
---------------------------------------------------------------

Consist=ConsistentR=Read Ahead Always|NR=No Read Ahead|WB=WriteBack|
AWB=Always WriteBack|WT=WriteThrough|C=Cached IO|D=Direct IO|sCC=Scheduled
Check Consistency
依次查看 /c0/v0……4，结果为 v0 raid1 其余四个逻辑磁盘均为 raid0
