Overview

The migration process from a non-HA installation to an HA installation is broken down into 3 steps:

  • A backup of your current installation
  • A fresh install on the two systems comprising the HA installation
  • Restore from the backup

Important Notes

Unsupported Configurations

Statseeker does NOT support the following configurations for physical (non-VM) installations:

  • Raid 5
  • Raid 6
  • SAN Drives

Installation HDD

User Accounts

The installation process will create the following administrative system accounts:

  • admin – the web user administrator account
  • statseeker – the system user account used by the Statseeker application
  • root – the superuser account in the backend operating system

You will be prompted to provide the root user password during the installation process. This password will become the default password for both the admin and statseeker accounts. This password can be changed after the installation process via:

  • the command line ssadmin tool
  • the web interface in the Administration Tool, see Admin Tool > Statseeker Administration > OS Configuration
Note: the password specified for your new HA installation does not need to be the same as that used for your current Statseeker installation.

Prerequisites

  • A current Statseeker installation
  • A license key that is compatible with a Statseeker High-Availability installation, contact Customer Service to ensure that you have a suitable key
  • A Statseeker High-Availability installation image/iso, contact Customer Service for access to the installation image

System Requirements

Ensure that both prospective HA servers meet the Version 5 System Requirements. In addition an HA installation requires that each server have a least two network interfaces and that are connected via a dedicated high-speed connection for the HA data sync link.

Installation Media

Contact Customer Service for access to the Statseeker installation ISO image file appropriate for your HA license. Once this file is downloaded, depending on the destination hardware, use CD/DVD writing software to open this ISO image file and burn the contents to a CD/DVD disc or copy the iso to a USB drive.

Configuration Information

You will also need to provide, or define, the following information during the install process:

  • The root user password for the server
  • A host name for the server
  • A domain name suffix for the server
  • Static IP, Netmask and Default Gateway addresses for the server
  • The IP address of your Domain Name Server
  • The SNMP read access community string to your devices (routers, switches, servers, etc.)

Backup Current Installation

For assistance with backing up your current Statseeker installation, please refer to Backup and Restore

Once the backup process is complete:

  • Verify the backup
  • Ensure that the verified backup is not being stored on any of the prospective Statseeker High-Availability servers as all data on those server will be erased during the installation process
