Open_basedir issue

file_exists(): open_basedir restriction in effect. [warning]
File(/etc/drush/drushrc.php) is not within the allowed path(s):
(/var/www/vhosts/:/tmp:/usr/local/bin:/usr/bin)
is_dir(): open_basedir restriction in effect. [warning]
File(/usr/share/drush/commands) is not within the allowed path(s):
(/var/www/vhosts/:/tmp:/usr/local/bin:/usr/bin)
file_exists(): open_basedir restriction in effect. [warning]
File(/var/www/settings.php) is not within the allowed path(s):
(/var/www/vhosts/:/tmp:/usr/local/bin:/usr/bin)
file_exists(): open_basedir restriction in effect. [warning]
File(/var/settings.php) is not within the allowed path(s):
(/var/www/vhosts/:/tmp:/usr/local/bin:/usr/bin)

How do I get around this?
Why is it calling for /var/www/settings.php or /var/settings.php

Thanks,
Chris
