Re: [ADSM-L] SV: SV: Deduplication number of sessions

Hi Christian

First thanks for your help ....... As you suggest I add in the dsm.opt the 
parameter   resourceutilization  10  , I run inc d:\*.* e:\*.* f:\*.* g:*.* 
h:*.* i:\*.*  -su=yes

But still got only 3 sessions and two mounts of file volume

Try this in your dsm.opt file
I have just copy and paste from the help menu in dsmc (C:\>dsmc help)

3.102.1 Regulating backup and archive sessions

When you request a backup or archive, the client can use more than one
session to the server. The default is to use a maximum of two sessions;
one to query the server and one to send file data. The client can use
only one server session if you specify a resourceutilization setting of
1.

When you request a backup or archive, the client can use more than one
session to the server. The default is to use a maximum of two sessions;
one to query the server and one to send file data. The client can use
only one server session if you specify a resourceutilization setting of
1. The client is also restricted to a single session if a user who is
not an authorized user invokes a UNIX or Linux client with
passwordaccess=generate specified.

A client can use more than the default number of sessions when
connecting to a server that is Version 3.7 or higher. For example,
resourceutilization=10 permits up to eight sessions with the server.
Multiple sessions can be used for querying the server and sending file
data.

Multiple query sessions are used when you specify multiple file
specifications with a backup or archive command. For example, if you
enter the following commands and you specify resourceutilization=5, the
client might start a second session to query files on file space B.

inc /Volumes/filespaceA /Volumes/filespaceB

Whether or not the second session starts depends on how long it takes to
query the server about files backed up on file space A. The client might

Hi,
That is probably because you only have 2 or 3 partitions on your server you try 
to backup.
TSM can only stream 1 session per local partition on the client.
