===== 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>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.</note>

=== 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

**Show controllers status**

	ssacli ctrl all show status

**Show detailed controllers information**

	ssacli ctrl all show detail

**Show controllers configuration**

	ssacli ctrl all show config

**Rescan for new devices**
Useful after swapping disks in bays, etc...
	
	ssacli rescan

**Show all physical disks (or their status) (controller slot 0)**

	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 pd all show detail

**Show logical drives (or their status) (controller slot 0, all or specific logical drive(s))**

	ssacli ctrl slot=0 ld all show
	ssacli ctrl slot=0 ld all show status
	
	ssacli ctrl slot=0 ld 1 show
	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
	ssacli ctrl slot=0 ld 1 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
