Linux Basics View hardware information

One: Quick View

1. View CPU information: Cat/proc/cpuinfo or LSCPU or

2. View card information: CAT/PROC/PCI

3. View USB Device: Cat/proc/bus/usb/devices

4. View PCI information: LSPCI (more intuitive than CAT/PROC/PCI)

5. View memory information: Cat/proc/meminfo or Free-m

6. View keyboard and mouse: Cat/proc/bus/input/devices

7. View system hard disk information and usage: Fdisk & disk–l & DF or lsblk or hdparm or Smartctl

8, detecting new hardware with hardware detection program Kuduz: Service kudzu start (or restart)

9. View Interrupt Request (IRQ) for each device: cat/proc/interrupts

10. View Boot Hardware detection infolog: DMESG more/var/log/dmesguname-auptime

11. View NIC Hardware information: Lspci|grep-i ' eth ' or Ethtool eth0

Several ways to view Linux version information:

1:uname-a

2:cat/proc/version

3:cat/etc/issue

4:lsb_release-a

5:cat/etc/redhat-release

6:rpm-q Redhat-release

Two: View hardware verbose commands

1.dmidecode: View All

2.smartctl: View Hard Drive

-I specified device

-d Specifies the device type, for example: ATA, SCSI, Marvell, Sat, 3ware,n

-A or a displays all information

-l Specifies the type of log, for example: Type:error, selftest, selective, Directory,background, Scttemp[sts,hist]

-H view hard disk health status

-T short background detection hard disk, time consuming

-T long background detection hard disk, long time consuming

-C-T Short Front desk detects hard drives and consumes less time

-C-T Long front desk detects hard drive and consumes time

-X interrupts background detection of hard drives

-l selftest display HDD detection log

HP HDD:

Smartctl-s on-d cciss,0/dev/cciss/c0d0 Turn on Smart

Smartctl-a-D cciss,0-i/dev/cciss/c0d0 Show all Smart info

Smartctl-l error-d cciss,0-i/dev/cciss/c0d0 View disk error log

Simply say SMARTCTL:SMARTD is installed by the Kernel-utils package by default. With the command RPM-QL kernel-utils can list the files in the Kernel-utils package, which is a daemon (a helper) that can monitor self-monitoring, analysis and reporting techniques (self-monitoring, analyses, and Reporting Technology-smart) of the hard drive.

Master configuration file:/etc/smartd.conf

Add a line/dev/cciss/c0d0-h-m [email protected]

3.megaCli: Check the hard drive (if the machine has a disk array, you cannot use Smartctl)
