hpacucli - Check RAID Information from Linux Shell

Have you ever tried to check how the hardware RAID Array configured on server from your Linux Shell? Have you ever wanted to change or modify your Hardware RAID configurations without rebooting the server and without leaving your Linux shell?

hpacucli utility is there to help you, If your server is HP Hardware. hpacucli  (HP Array Configuration Utility CLI) is a command line based disk configuration program for Smart Array Controllers and RAID Array Controllers. You can download and  install hpacucli tool from HP website.

Quick Abbreviations:

chassisname = ch
controller = ctrl
logicaldrive = ld
physicaldrive = pd
drivewritecache = dwc

As root, just type "hpacucli" and you will be into hpacucli command line interface. Let me give you a quick example of what you can do with this hpacucli.

To Get the quick details about the RAID controller and its Health:

=> ctrl all show status

Smart Array P400 in Slot 9
   Controller Status: OK
   Cache Status: OK
   Battery Status: OK

=>

To get a quick idea of How the disks are grouped and which raid level used:

=> ctrl all show

HPASMCLI - Overview and Commands

hpasmcli stands for HP Server Management Application and Agents Command Line Interface


It comes with HP ProLiant Support Pack (PSP) and can be installed in HP ProLiant Servers to view, modify the BIOS / System settings such as  hyper-threading, boot sequence control, and UID LEDs, etc. It can also be used to display hardware status  of the HP ProLiant servers. 

It’s a scriptable command line interface for interacting with the hpasm management daemons.

hpasmcli is also usable for incorporating into shell scripts. Hpasmcli supports TAB completion of command names and has a history buffer that can be accessed using the up/down arrows.

Finding BIOS version in Linux Servers

In a day to day system administrative tasks, you may need to find out BIOS version of your servers. In Linux, you can find out the BIOS version without rebooting the server. dmidecode command can be used to achieve this.


Command : dmidecode --type 0


[root@testsrv1 ~]# dmidecode --type 0
# dmidecode 2.7
SMBIOS 2.5 present.

Collecting Server Hardware Information in Linux

To Print Entire Hardware Information - dmidecode

To List PCI devices - lspci 

To List USB devices - lsusb

To Find CPU Information - cat /proc/cpuinfo

To Find Memory/RAM in Information,

    1. cat /proc/meminfo
    2. free -m

To find Hard disk Information,

• fdisk –l
• df –h
• vgdisplay
• lvdisplay

To Know SWAP information,

   cat /proc/swaps

To detect Hardware Changes,

    service kudzu restart

To See Kernel Version, Architecture, OS Release Version, etc..

• uname –a
• cat /etc/redhat-release
