MegaCLI is a pain… a real pain. I’m not a fan of the syntax, it’s not easily readable, did I say it was a pain?

Well, our OCP Knox Units are connected via the LSI MEGARAID SAS 9286CV-8E (SGL) controller, so I’ve been using MegaCLI quite a bit lately. Here is a collection of my working examples:

List All Devices

./MegaCLI -PDList -aALL | egrep 'Adapter|Enclosure|Slot|Inquiry'

Create raid 1 volume with disk 0 and 1

./MegaCLI -CfgLdAdd -r1' [38:0,38:1]' -a0

Create raid 5 volume with disk 0-14

./MegaCLI -CfgLdAdd -r5 '[38:0,38:1,38:2,38:3,38:4,38:5,38:6,38:7,38:8,38:9,38:10,38:11,38:12,38:13,38:14]' -a0 -NoLog

Create individual raid 0 volumes on drives 2-14

i=2; while [ $i -le 14 ] ; do ./MegaCli -cfgldadd -r0 [38:${i}] WB RA Cached CachedBadBBU -strpsz512 -a0 -NoLog ; i=`expr $i + 1`; done

List  all volumes

./MegaCli -LDInfo -Lall -aALL

Create raid 50 volume

./MegaCli -CfgSpanAdd -r50 -Array0[38:0,38:1,38:2,38:3,38:4,38:5] -Array1[38:6,38:7,38:8,38:9,38:10,38:11] Direct RA WB -a0

Bring physical drive 14 online

./MegaCli -PDMakeGood -PhysDrv[38:14] -a0

Show physical drive status

./MegaCli -PDList -a0

Enable JBOD support – this is necessary for vSphere vSAN technology

./MegaCli -AdpSetProp -EnableJBOD 1 -aALL

Set global hot spare

./MegaCli -PDHSP -SET -PhysDrv [38:14] -a0

Delete all volumes

./MegaCli -CfgLdDel -Lall -aAll

Clear foreign configs

./MegaCli -CfgForeign -Clear -aALL

List drive state

./MegaCli pdlist -a0 | grep 'Firmware state'

Enable drive location LED

./MegaCli -PdLocate -start -physdrv[64:0] -a0
