HP Smart Storage Admin CLI (ssacli) installation and usage on Proxmox PVE (6.x)

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

Command examples

Here are few examples of ssacli commands that you can use to diagnose and manage your HP Smart Storage Controller.

Show available controllers

ssacli ctrl all show

ssacli ctrl all show config

ssacli ctrl slot=0 pd all show
ssacli ctrl slot=0 pd all show status

Show all physical disks detailed information (controller slot 0)

ssacli ctrl slot=0 ld 1 show status

Show detailed logical drives information (controller slot 0, all or specific logical drive(s))

ssacli ctrl slot=0 ld all show detail

Show array information (controller slot 0, array A)

ssacli ctrl slot=0 array a show

Show array status (controller slot 0, all arrays)

ssacli ctrl slot=0 array all show status

Create new RAID 0 logical drive (controller slot 0, disk in port 1I:box 1:bay 1)

ssacli ctrl slot=0 create type=ld drives=1I:1:1 raid=0

Create new RAID 1 logical drive (controller slot 0, disks in port 1I:box 1:bay 1 and 2)

ssacli ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2 raid=1

Create new RAID 5 logical drive (controller slot 0, diks in port 1I:box 1:bay 1 to 4)

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

Add spare disks (controller slot 0, logical drive 1, array A, disks in port 1I:box 1:bay 6 and 7)

ssacli ctrl slot=0 array a add spares=1I:1:6,1I:1:7

Add global spare disks (controller slot 0, logical drive 1, all arrays, disks in port 1I:box 1:bay 6 and 7)

ssacli ctrl slot=0 array all add spares=1I:1:6,1I:1:7

Turn on/off blink logical drive LED (controller slot 0, logical drive 1)

ssacli ctrl slot=0 ld 1 modify led=on
ssacli ctrl slot=0 ld 1 modify led=off

Turn on/off blink physical disk LED (controller slot 0, physical disk port 1I:box 1:bay 1)

ssacli ctrl slot=0 pd 1I:1:1 modify led=on
ssacli ctrl slot=0 pd 1I:1:1 modify led=off

Modify smart array cache read and write ratio (controller slot 0, cacheratio 80% read/20% write)

ssacli ctrl slot=0 modify cacheratio=80/20

Show physical drive write cache status (controller slot 0)

ssacli ctrl slot=0 modify dwc=?

Enable/disable physical drive write cache (controller slot 0) Important: Because physical drive write cache is not battery-backed, you could lose data if a power failure occurs during a write process. To minimize this possibility, use a backup power supply.

ssacli ctrl slot=0 modify dwc=enable
ssacli ctrl slot=0 modify dwc=disable

Show status of smart array write cache when no battery is present (no-battery write cache option, controller slot 0)

ssacli ctrl slot=0 modify nbwc=?

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

Proxmox is Debian based, so that is quite strange that you have troubles installing it on this distro...
