The tmsh save sys config file /var/tmp or /shared/tmp or a relative path to these directories (for example, /config/../shared/tmp) saves the scf with the specified real path. However, since the /var/tmp directory is used internally by BIG-IP daemons, some functionality may be rendered unusable till the /var/tmp symlink to /shared/tmp is restored.
Some system functionality may be rendered unusable.
Saving the sys config file /var/tmp or /shared/tmp (or a relative patch to one of these directories).
Use the following commands to delete the scf and restore the symlink and reset the permissions of the /shared/tmp directory: -- rm -f /var/tmp -- ln -s /shared/tmp /var/ -- chmod 01777 /shared/tmp -- bigstart restart
The /var/tmp or /shared/tmp are now invalid paths for the tmsh save sys config file command.
