17 Remove the software

17.1 Remove HELIOS products from the server

: Mount the ISO image burnt to physical disc or the ISO image file.

The correct commands for your specific computer are stated in the “First Steps” guide.

Example:

(Linux)

# mkdir -p /mnt/helios
# mount -r /dev/cdrom /mnt/helios
# cd /mnt/helios
# ./installer

: As soon as you have entered the last command, HELIOS Installer will be started (Fig. 17.1). To uninstall the HELIOS software select Remove HELIOS Products from the main menu and press RETURN.

There is also an alternative option to remove all software products from the server:

# cd /usr/local/helios 
# bin/stop-helios now
# sbin/uninstall base

Please be aware that this command will remove all installed HELIOS products from the server!

The Removable Products item shows all HELIOS software products which can be removed from the server (Fig. 17.2).

The following example shows an uninstallation procedure where PCShare is about to be removed.

Fig. 17.2: HELIOS Installer – Remove HELIOS products

: In the Removable Products section highlight the product you want to remove and press the space bar, so it becomes marked (see Fig. 17.2). To deselect one (or more) item in the list, press the space bar again.

The example in Fig. 17.2 shows that Base (with Base Data) and EtherShare are supposed to remain on the server, and PCShare is about to be removed.

Note:: Starting the uninstallation will stop all HELIOS services running on the server. Therefore, please make sure all HELIOS users are logged-out before you uninstall a product. To verify the HELIOS user status you can use 8.6 “swho”.

: After you have marked all products that you want to remove confirm with Ok.

The window in Fig. 17.3 informs you about the software removal status.

: Leave the installation menu with Esc or Ctrl-X (see 4.1.6 “Navigating within HELIOS Installer”) to get back to the main menu.

Note:

Uninstalling the HELIOS software or parts of the software, will not remove any configuration files nor volume or spool directories. This allows installing the software again using all existing configuration data.

To remove all HELIOS files after the software removal do the following:

# cd /usr/local
# rm -rf helios
Then remove all HELIOS spool directories.
Remove all user volumes.

: Make sure that the Please select pull-down menu shows the entry Deinstallation, and click Continue.
