Hello Joe,
as far as i know, the only way to use the diskpool in a LAN free environment,
is to use SANErgy in addition to TSM.

Subject: Re: LAN Free backups
Actually it was something I missed (another TSMer fill me in..Thanks). 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)??
Joe

Joe,
Are you seeing the Agent make communications to the Server when recycled ?
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.

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
