The Cache Manager maintains a list of foreign cells that it knows how to reach. A cell must appear in the list for you to access its AFS filespace. (In addition, the ACL on each directory in the pathname to the file must grant you the necessary permissions, and your system administrator must mount the cell in the local AFS filespace--by convention, just under the /afs directory.)
Issue the fs listcells command to display the cells you can access from this client machine. It can take several minutes for the command shell prompt to return. The Cache Manager stores the machines as IP addresses, but has the addresses translated to names before displaying them. To have the command shell prompt return immediately, use the ampersand (&) to run the fs listcells command in the background as in the following example.
% fs listcells & Cell abc.com on hosts db1.abc.com db2.abc.com db3.abc.com Cell test.abc.com on hosts test4.abc.com. Cell stateu.edu on hosts sv5.stateu.edu. sv2.stateu.edu. sv11.stateu.edu. Cell def.com on hosts serverA.def.com
