Become friendly with RAID CLI

We have a lot of RAID technologies and it’s difficult to automate creation, managment … Below we will find bases commandes for 3ware (tw-cli), Areca (cli), Hp (hpacucli), Dell (megacli).

requirement

Before starting, ensure to have the good repository in your sourcelist

Debian

echo "deb http://hwraid.le-vert.net/$(lsb_release -s -c) branch main" > /etc/apt/sources.list.d/hwraid.list

wget -O - http://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key | sudo apt-key add -
http://hwraid.le-vert.net/wiki/DebianPackages

 

If you haven’t¬†lsb-release package installed, change the distrib codename manually.

#or rpm
rpm -i ftp://ftp.hp.com/pub/softlib2/software1/pubsw-linux/p414707558/v59422/hpacucli-8.50-6.0.noarch.rpm

Usage

Useful to know : To expand RAID size, it requires that the controller board has a battery. Otherwise, the option is not available.

Informations

Display raid controllers and serial number

hpacucli ctrl all show

Display status of raid controllers

hpacucli ctrl all show status

Display drive connected on the raid controller slot 0

hpacucli ctrl slot=0 pd all show

Display details of controller 0 (cache …)

hpacucli ctrl slot=0 show

Display configuration of controller 0

hpacucli ctrl slot=0 show config
hpacucli ctrl slot=0 show config detail

Status of raid volumes

hpacucli ctrl slot=0 logicaldrive all show status

Display features of volume (logicaldrive) 1

hpacucli ctrl slot=0 ld 1 show

Display features of a drive

#find a S:E (slot:enclosure)
hpacucli ctrl slot=0 physicaldrive all show

#Select your drive
hpacucli ctrl slot=0 physicaldrive 1I:1:1 show

Managment

Delete raid on controller 0

hpacucli ctrl slot=0 delete forced

Create a RAID 1 volume

hpacucli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2 raid=1

Expand volume size

hpacucli ctrl slot=1 ld 1 modify size=max

If you controller haven’t cache, enable drive cache

hpacucli ctrl slot=5 modify dwc=enable

Sets the array accelerator cache ratio for the controller

hpacucli ctrl slot=0 ld 1 modify arrayaccelerator=enable

hpacucli ctrl slot=0 ld 1 modify cacheratio=25/75
# The first # is the read cache %.
# The second # is the write cache %.

 

Convert RAID 0 to RAID 1

If you need, add new drive in your volume

hpacucli ctrl slot=0 ld 1 add drives=2I:1:1

Modify raid type to RAID1
