Using perccli with Dell PE R710 and Perc 6/i

Intro

Dell uses raid controllers from LSI.

The megactl utility should therefore work with all PERC raid controllers.

The Dell-provided CLI-raid-utility is for Ubuntu 16.04 and rather old, so I decided to try out this third-party utility instead.

This guide has been tested on PERC7 as well and found to work.

Assumptions

Using Debian Buster with a Dell R710 and PERC 6/i.

root@dragonborn:~# lspci -nn
...
03:00.0 RAID bus controller [0104]: LSI Logic / Symbios Logic MegaRAID SAS 1078 [1000:0060] (rev 04)
...

root@dragonborn:~# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)
Release:        10
Codename:       buster
root@dragonborn:~#

Howto

Add repo to OS.
# echo "deb http://hwraid.le-vert.net/debian buster main" > /etc/apt/sources.list.d/hwraid.list

Add repo key.

# mkdir /root/Downloads
# cd /root/Downloads
# wget https://hwraid.le-vert.net/debian/hwraid.le-vert.net.gpg.key
# apt-key add hwraid.le-vert.net.gpg.key

Install megaraid-status and megacli.

# apt update
# apt-get install megaraid-status megacli

If the installation from §3 fails for some reason on Debian Buster, try downloading the packages below, using the url in the repo-file. Then install them with dpkg, followed by a apt install -f and or apt --fix-broken install.

In other words, use this url; https://hwraid.le-vert.net/debian/pool-buster/.

Note that the Debian Buster-packages works on Debian Bullseye as well (as of 2023-05-15).

# cd /root/Downloads
# apt-get install -f ./megactl_0.4.1+svn20090725.r6-7+Debian.buster.10_amd64.deb
```
megacli_8.07.14-2+Debian.buster.10_amd64.deb
megaraid-status_0.13+Debian.buster.10_all.deb
libc6-i386
megactl_0.4.1+svn20090725.r6-7+Debian.buster.10_amd64.deb
daemon
```
Done. Test it out with the commanda in the tips and tricks part.

Command tricks and tips

In no particular order. These three command should get you going fairly quick.

Show logical drive 0 on adapter 0 status and type

Of particular interest is the Ongoing Progresses line, This raid array is initializing, and has been doing so for a while.

Display and adjust automatic rebuild status on adapter 0

root@dragonborn:~# megacli -AdpAutoRbld -Dsply -a0

Adapter 0: AutoRebuild is Enabled.

Exit Code: 0x00

Info on rebuild rate on https://jackal777.wordpress.com/2015/05/29/adjust-raid-rebuild-rate/.

root@dragonborn:~# megacli -AdpGetProp RebuildRate -a0

Adapter 0: Rebuild Rate = 30%

Exit Code: 0x00
root@dragonborn:~# megacli -AdpSetProp RebuildRate 60 -a0

Adapter 0: Set rebuild rate to 60% success.

Exit Code: 0x00
root@dragonborn:~# megacli -AdpGetProp RebuildRate -a0

Adapter 0: Rebuild Rate = 60%

Exit Code: 0x00
root@dragonborn:~#

The rebuild rate can be set for software raids as well. The keywords to note here are speed_limit_max and speed_limit_min.
Preferably set the max and min values to the same high number.

See eg this site for more information; https://www.cyberciti.biz/tips/linux-raid-increase-resync-rebuild-speed.html.

The line Firmware state is of interest, this line states what the drive is doing, if anything.

If a drive is rebuilding, show the progress as below.

In this case the rebuilding drive is 32,1; ie enclosure id 32 and slot/drive 1.

# megacli -PDRbld -ShowProg -PhysDrv [32:1] -aALL

Rebuild Progress on Device at Enclosure 32, Slot 1 Completed 51% in 10 Minutes.

Find and blink a specific disk in a particular bay

For use when you eg need to replace a disk and it's difficult to see which one is shining amber instead of green.

First, only show bad drives

Legend

e32: denotifies which bay.
s0, s2: denotifies which disk in the above bay.

Then seek out the specific drives.

In bay 32 on raid controller a0, blink disk in slot 0 until turned off.
# megacli -PdLocate -start -physdrv[32:0] -a0
# megacli -PdLocate -stop -physdrv[32:0] -a0

In bay 32 on raid controller a0, blink disk in slot 2 until turned off.
# megacli -PdLocate -start -physdrv[32:2] -a0
# megacli -PdLocate -stop -physdrv[32:2] -a0
