I just implemented LanFree backups across a SAN for Solaris. I have one
Solaris client , a Solaris TSM server, and an IBM 3583 LTO tape library all
connected to a SAN. We are not using a TDP yet but are backing up all files
LanFree directly to tape.

You cannot have a disk storage pool defined at all in the domain you are
using for LanFree backups.

The backup will go directly to tape unless there is a problem with the SAN
then it will go to the TSM server across the LAN.

Your mount points cannot exceed your defined tape drives.

The documentation states to use disk storage you can use SanEnergy but we
haven't looked at this.

The only problem we have had is storage agent sessions that start every
couple of hours and hang up on the TSM server. So far it seems they do not
time out. We have been cancelling them and are working with TSM support to
fix this problem.

Subject:  LAN Free (SAN) Backup



Hello,

I will soon implement my first TSM Server on a SAN network.

The SAN is connected with a MA8000 storage server, 5 NT clients, and 1 Sun
Unix server
Each machine has local disk + san-attached storage and will use TDP for
oracle to make backups
(data on the MA8000).

I read that a backup/archive of regular files is also possible since TSM
4.2.

Now, is it correct that with LAN-Free backup :

                - I can't use diskpools (on the SAN), with migration (next
storage pool)
to the tapelibrary, over the SAN ?
                - You always make a "direct connection" from the backup
client to the
storage device which takes the backup
                  (tape).  So data transfers twice through the SAN-switch ?
