Joe, It is interesting that you can't have a disk storage pool defined in the management class storage hierarchy or client won't use the LAN path, even if there aren't any volumes in the diskpool.
Yes, you can use the FILE device type and set up a hierarchy in the same way you would use a disk pool - set maxsize on a storage pool made of the FILE device type so that larger files go to tape and the smaller files stay on disk. However, the last time I checked you must have SANergy to use this feature so that you can define the files to both systems. I haven't used this method yet.

I needed to create a new policy for these nodes and direct them to teh tapes instead of the disk storage pools. I have also noticed a slow down. I use colocation for my local copies and since I am sending mostly large files from this node I see a backlog of sessions just sitting at MEDIAW. So not I went from a 10 session connection to a 1 session connection. Great it goes directly to tape, but is there any way to utilize the LAN Free path to use the diskpool as well if the file is lower than a certian size (like a regular disk storage pool)??

Is the Server receiving the mount request from the Agent ? Any changes to the device configurations on the server that effect the Agent (other server) need to recycle agent. If you want to send portion of activity log and oter messages, we can take a look see. Are the device names on the Client the same as the Server ? What levels of TSM? Performance note : If the client supports SHAREDMEM / NANEPIPES these in my testing have provided the best performance especialy where the client and Agent talk there is no TCP/IP overhead. Biggest Advantage I see todate is that all that big I/O ( Data Bases ) are removed from the LAN traffic and other tentents act better who need LAN. The other big difference is that during a LAN backup the client is somewhat working hard ( 35% - 40% or more ) moving data using IP stacks. Performed testing where I had four drives writing to 3590 @ native speeds + during a DB2 run where the engine was 79% idle during the run. This is the biggest advantage to date for LAN-Free. Predicting performance over the SAN is another animal for another day. My two cents. ----- Original Message ----- From: "Joe Cascanette" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, March 05, 2002 2:53 PM Subject: LAN Free backups I am having some problems with the LAN Free backups. Server is 4.2.1.12 (Windows 2000), client is 4.2.1.20, SAN client is installed and I guess setup. I see the node in question connecting to the TSM Server (under q ses I can see the node and its session type is server). When I launch the client it does not give me a "LANFree path failed. Using LAN Path" anymore. I have mapped all the drives to this server to use. Is there something missing?. When the backups start no tape is loaded, it goes to the storage pool (unless it is over 500Megs which goes directly to tape). This is also causing a problem when I try to restore to the original location for this SAN attached server - File is unavailable to the server. So I need to launch the client (login as this node) on another machine and save the files to a different location. TSM server is connected to the library via fibre switch. All nodes for LAN free backups are connected to this fibre switch and are able to see all the drives in the TSM admin GUI. The service "TSM StorageAgent1" is created and is running. Thanks for any help Joe
