# HPE MSA 2040 Storage by HTTP

## Overview

The template to monitor HPE MSA 2040 by HTTP.
It works without any external scripts and uses the script item.

## Requirements

Zabbix version: 7.2 and higher.

## Tested versions

This template has been tested on:
- HPE MSA 2040 Storage

## Configuration

> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.2/manual/config/templates_out_of_the_box) section.

## Setup

1. Create a user with a monitor role on the storage, for example "zabbix".
2. Link the template to a host.
3. Set the hostname or IP address of the host in the {$HPE.MSA.API.HOST} macro and configure the username and password in the {$HPE.MSA.API.USERNAME} and {$HPE.MSA.API.PASSWORD} macros.
4. Change the {$HPE.MSA.API.SCHEME} and {$HPE.MSA.API.PORT} macros if needed.

The RAID6 disk group has one inaccessible disk. The disk group is fault tolerant but degraded. If the inaccessible disks come online or if after 60 seconds from being quarantined the disk group is QTCRor QTDN, the disk group is automatically dequarantined.</p><p>- QTOF: Quarantined offline. The disk group is offline with multiple inaccessible disks causing user data to be incomplete, or is an NRAID or RAID 0 disk group.</p><p>- QTUN: Quarantined unsupported. The disk group contains data in a format that is not supported by this system. For example, this system does not support linear disk groups.</p><p>- STOP: The disk group is stopped.</p><p>- UNKN: Unknown.</p><p>- UP: Up.
