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:
- Hyper-threading (also known as logical processing or logical processors), you will need to disable this feature in the BIOS prior to commencing the installation process
-
In the instance of physical (non-VM) installations, the following are NOT supported:
- Raid 5
- Raid 6
- SAN Drives
- Virtualized High-Availability installations
Installation HDD
- All data on the hard disk will be deleted during a new install
- See Version 5 Hardware Requirements for more information on HDD requirements
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
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
Hardware Requirements
Ensure that both prospective HA servers meet the Version 5 Hardware 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 cable 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
