Un-installing Rational ClearCase in a non-global zone

Before you un-install Rational® ClearCase® from a computer where you have configured non-global zones with LOFS (loopback file system) directories, there are extra configuration steps you must perform as part of the de-installation process.

If you have followed the procedures in Tuning the MVFS cache for a non-global zone using cleartool setcache to set up a zone-specific configuration directory and mount it via LOFS, you must remove that mount entry in order to un-install Rational ClearCase from the system completely.

In the global zone, unshare the configuration directory that is loopback mounted into the non-global zone.
1. Log on to the global zone as root.
2. Use the Solaris zonecfg application to unshare the configuration directory.
  zonecfg -z ngz_name
3. At the zonecfg prompt, type remove fs to remove the fs entry that directs the system to loopback mount the zone-specific MVFS configuration directory onto the non-global zone.
  Note: You must use the full path name (/var/adm/rational/clearcase/...). Symbolic links are not supported by zonecfg.
4. Verify and commit the changes, and then exit the zone configuration application:
  verify commit exit
Reboot the non-global zone ngz-name.
Uninstall Rational ClearCase in the non-global zone.

After all non-global zone fs entries are removed, uninstall Rational ClearCase in the global zone if necessary.
