WARNING: This documentation covers Parallels H-Sphere versions up to 3.1. For the latest up-to-date Parallels H-Sphere documentation, please proceed to the
official Parallels site.
This document explains how to recreate H-Sphere 2.4.x services,
users, and resources on a particular non-CP Linux/Unix box. For the CP server, see
Recovering Control Panel. Servers are
recreated on empty machines with a newly installed operating system.
See also how to recover H-Sphere Unix servers in
H-Sphere 2.5 and up and in
H-Sphere 2.4.1 Patch 2 and earlier.
Servers are recreated by means of a Perl script inluded into H-Sphere
distributions starting with version 2.4 Patch 3.
You must have all user content and configuration files backed up.
- Prepare the server
To start the recreate, you need to set up a clean server with the IP address of the server you
are recreating and prepare it for H-Sphere installation.
We don't recommend setting up updated versions of integrated party software at this point. Please
stick to the original versions.
- Download the installer
Download and untar the installer of the H-Sphere version you were running on the crashed server.
See the list of H-Sphere versions.
If you already have an older version of hsinst.tgz in the current directory,
please remove or rename this file before the download.
- Run the recreator
Run the recreator on the CP server as root:
It will allow you to select the server to recreate, and will take you through the recreation wizard.
Once it finishes, the server will be up and running.
- Restore user content
If you are recovering servers with user content, such as web, mail, or mysql,
postresql, you need to restore user content from backup. This is not necessary for DNS servers.
To restore data from the backup, check with the backup and recovery list
for for this server. Restore listed directories from /var/backup/<ARCHIVE>.tgz
or custom backup directory into the appropriate locations.
