EMC VoyenceControl – Release Notes
(22943) – "Error: Version Already Installed" Message after a Failed install
or Upgrade
The "Version Already Installed" message indicated that enough of the product was
installed to make it appear that the new version is present. This could happen when
the installation is aborted or stopped in the middle of execution.
The steps below are provided as a work-around for this scenario if you receive this
error message when re-installing after a failed install or upgrade. Possible failure
scenarios include lack of sufficient disk space and/or loss of terminal session during
install/upgrade.
Install Workaround
If you receive the "Version Already Installed" error when attempting to re-install after a failed
install, the simplest approach is to uninstall, and then re-install. Run the uninstaller per the
instructions in the VoyenceControl Installation Guide. If the uninstall fails to run, complete the
following steps:
1. Stop all VoyenceControl services using:
/etc/init.d/vcmaster stop (Linux/Solaris)
“[Product Directory]\bin\ncmmaster.pl” stop (Windows)
2. Remove the VoyenceControl installation directory (Note: this deletes all VoyenceControl
data).
3. Remove the /etc/voyence.conf file (Linux and Solaris only).
4. Ensure that the failure condition is fixed (enough disk space, run session through screen
or VNC).
5. Run the install again.
Upgrade Workaround
If you receive the "Version Already Installed" error when attempting to re-install after a failed
upgrade, you can modify the current version number to allow the upgrade to continue. The
following steps should only be used if data migration has completed successfully, the upgrade
failed, AND you are receiving the "Version Already Installed" message when re-running the
upgrade.
1.
Change the current VoyenceControl build number. The build number is the last number
in the version. Change it to one less than its initial value. For example, if the line reads
4.1.0.850, change it to 4.1.0.849.
Linux/Solaris:
Edit the /etc/voyence.conf file and modify the VERSION line at the top.
Windows:
Edit the registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Voyence\Control\Configuration\VERSION
2. Ensure that the failure condition is fixed (enough disk space, run session through screen
or VNC).
3. Run the install again.
