Become friendly with RAID CLI
talset | linux, raid |
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.

cli disk info drv=X
Create a RAID set with drive 1 and 2
cli rsf create drv=1,2 name=raidset1
Create a volume RAID
#vsf create <raid=xx> <capacity=xxx> <level=<0:1:3:5:6>> [ch=<0>] [id=<0~15>] [lun=<0~7>] <name=xxx> [tag=<Y:N>] [cache=<Y:N>] [stripe=<4:8:16:32:64:128>] [fginit=<Y:N>]
cli vsf create raid=1 capacity=2000 level=1 name=volume1 fginit=N
Display controller configuration
Change priority of disk in port 2 to speed up raid rebuild
Verify the rebuild progress
Display details of raid volume 2
To prevent removing the wrong drive. Active LED blinking on drive 19

HP / Hpacucli
Installation
#debian
apt-get install hpacucli
#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
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
hpacucli ctrl slot=0 ld 1 modify raid=1
