Hi,

Depends (love that statement) on the type of restore. If you have a no-query
restore, the tsm server will restore the data in a "as few mounts as
possible way", if you have a query restore the client will ask the tsm
server for a object (being file or directory), so the TSM server can not do
its thing to minimize the number of tapemounts.

>From the read.me:

No query restore
When you enter an unrestricted wildcard source file specification on the
restore command and do not specify any of the options: inactive, latest,
pick, fromdate, or todate, the client uses a different method for retrieving
files and directories from the server. This method is called no query
restore because instead of querying the server for each object to be
restored, a single restore request is sent to the server. In this case, the
server returns the files and directories to the client without further
action by the client. The client merely accepts the data coming from the
server and restores it to the destination named on the restore command

Regard,

Karel
