DRM and file based copy storage group

[yoda woya]

Can the copy group of a primary file based storage pool point to a file
based copy storage pool.  Is so, how does DRM handle the failure of the TSM
server or the primary storage pool.  If any one is doing this please give me
as much insight as you can.   I would like to set a copy stgpool on a remote
disk array for DRM and not sure if this is possible.
