Reveal Time Machine Disks Hidden by Lion Server

Apple Mac OS X Lion Server 10.7.2 hides Time Machine volumes when it is installed. Lion Server limits the number of volumes for client Time Machine backups to one. We prefer to have a Time Machine volume for each client that uses server attached Time Machine disks.

There is a work around. Execute the following, replacing clientTM with the share name of your disk.

sudo defaults write /private/var/db/dslocal/nodes/Default/sharepoints/clientTM timeMachineBackup '(1)'

Thanks to this support discussion for the answer.
