HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)
Why use HP Smart Storage Admin CLI?
You can use ssacli (smart storage administrator command line interface) tool to manage any of supported HP Smart Array Controllers in your Proxmox host without need to reboot your server to access Smart Storage Administrator in BIOS. That means no host downtime when managing your storage.
CLI is not as convenient as GUI interface provided by BIOS or desktop utilities, but still allows you to fully manage your controller, physical disks and logical drives on the fly with no Proxmox host downtime.
ssacli replaces older hpssacli, but shares the same syntax and adds support for newer servers and controllers.
Installation
Installation process of the ssacli package on Proxmox is the same as on any other Debian based system.
NOTE: HP does not provide Buster repository for Debian 10/Proxmox 6.x, but we can still use Stretch repository even that it's targeted for Debian 9/Proxmox 5.x.
Add HP's MCP repository
To add HP's MCP repository to apt sources list use this command:
echo "deb http://downloads.linux.hpe.com/SDR/repo/mcp stretch/current non-free" > /etc/apt/sources.list.d/hp-mcp.list
Download and add public keys for the MCP repository
Public keys are needed by apt to verify repository signatures, so we need to download and add them. There are four of them and we need to download and them all:
wget -q -O - http://downloads.linux.hpe.com/SDR/hpPublicKey1024.pub | apt-key add -
wget -q -O - http://downloads.linux.hpe.com/SDR/hpPublicKey2048.pub | apt-key add -
wget -q -O - http://downloads.linux.hpe.com/SDR/hpPublicKey2048_key1.pub | apt-key add -
wget -q -O - http://downloads.linux.hpe.com/SDR/hpePublicKey2048_key1.pub | apt-key add -
Installing the ssacli package
First, we need to update available packages:
apt update
And then we can install the ssacli package:
apt install ssacli
Using the ssacli tool
Command short and long names
All commands have a short name to reduce the length of the total input provided to the ssacli tool. You can use short or long name. Here is a list of all commands and their long and short names:
- chassisname = ch
- controller = ctrl
- logicaldrive = ld
- physicaldrive = pd
- drivewritecache = dwc
- licensekey = lk
You can specify disks also as:
- A range of drives (bay 1 to 3): 1I:1:1-1I:1:3
- Drives that are unassigned: allunassigned

ssacli ctrl slot=0 create type=ld drives=1I:1:1-1I:1:4 raid=5
Delete logical drive (controller slot 0, logical drive 1)
ssacli ctrl slot=0 ld 1 delete
Add new physical disks to logical drive (controller slot 0, logical drive 1, disks in port 1I:box 1:bay 6 and 7)
ssacli ctrl slot=0 ld 2 add drives=1I:1:6,1I:1:7

Hi! Thanks for this. Have you tried installing the hpasmcli tools? Can't do it in Debian
