HP Smart Array P420i Array Management in ESXi 5.5
The tool you should be using today is hpssacli
. The older hpacucli
utility doesn't work on current-generation ProLiant servers.
In case you don't have hpssacli
, the support download bundle for your server is here (if you're not already using the HP ESXi build).
Also, RAID6 for 4 disks doesn't make sense. Do RAID 1+0

I have a HP DL380p Gen8 server with ESXi 5.5 running on it and HP Smart Array P420i. I've installed 4 new hard disks on it and want to put them in a RAID 6 array (Although RAID 10 would be OK too).
Hoping to run hpacucli, this is what I thought would work: http://www.virtualtothecore.com/en/manage-an-hp-smart-array-directly-from-vmware-esxi/
But now, when I run hpacucli via esxcli, I get this error:
Error: No controllers detected.
Is there anything I forgot? Or any advice how to find the problem?

ewwhite over 10 years@MohammadrezaMontazeriShatoori There's a performance penalty. RAID 1+0 with 4 disks will perform better.

pauska over 10 years@MohammadrezaMontazeriShatoori RAID6 requires two parity disks, which leaves you with the same usable storage as RAID 1+0 does. RAID1+0 performs a lot better.

Mike S over 8 yearsAnd if
hpssacli
showsno controllers detected
, runmodprobe sg
and try again, as per support.hp.com/id-en/document/c04647234 . This is a problem today on RHEL/Centos 7.1. -
mwfearnley about 6 yearsI would say that RAID 6 does "make sense" for four disks, and unlike RAID 1+0 it does allow any two drives to fail without losing integrity. The obvious trade off is the speed, but I would reserve a term like "doesn't make sense" for logical impossibilities like RAID 10 on three disks, or RAID 6 on two disks.
