This procedure should be performed only for vserver build 1056256121 (H-Sphere 2.3.1 RC 2).

1. Check the VPS build:
   # cat /proc/vservers/setup | grep "vserver build"
   You will get something like this:
   vserver build 1056256121
   If your vserver build is less than 1056256121, plase update your kernel.
2. Check the Virtual Private Server tools version:
   # rpm -qa|grep hsphere-vps
   You will see something similar to:
   hsphere-vps-0.98-29
3. Suspend all VPS before the server reboot:
   # cd /hsphere/shared/scripts
   # ./vps-suspend.pl -a
4. Uninstall old VPS tools:
   # rpm -e hsphere-vps-x.xx-xx
   where x.xx-xx is the old VPS version and release number.
5. Download and install new VPS tools:
   where y.yy-yy is the new VPS tools version and release number.
6. It is also recommended to install the latest VPS package (for now, it is hsphere-vps-0.98-30.noarch.rpm):
   # rpm -ivh hsphere-vps-0.98-30.noarch.rpm
7. Run update script:
   # cd /hsphere/shared/scripts/
   # ./vps-update.pl
8. Run configuration script:
   # ./vps-configure.pl
   and follow the script instructions step by step.
9. Resume suspended VPS:
   # cd /hsphere/shared/scripts
   # ./vps-resume.pl <vps_name>
   where <vps_name> is a suspended VPS server name.
   To resume all suspended VPS servers, run:
   # ./vps-resume.pl --all
