With TSM V5.1 and below a drive has to be defined, visible, and online to the TSM server and the SAN Storage Agent. Essentially, the SAN Storage Agent is a cut down TSM server code set that does its database I/O remotely. You have another option, install the TSM server code where you were going to install the SAN agent. Consider one important item, even if TSM did support what you wanted. The link over the IP potentially has a lot of meta data to move back and forth. With a single thread SAN like solution, this may not be the best choice.
TSM V5.2 will likely have improvements in SAN attachment configuration operations to address drives being visible to the TSM server and all SAN clients, but there is nothing announced. So, we will have to see. The library probably supports LAN-Free connections by using a SCSI address to talk to the library. Paul D.

We have our main data center with the big TSM server in Boise, Idaho. We have a smaller data center with a small SAN in Phoenix, AZ, about 2000km away. The Phoenix data center has its own SAN that is just a little too large to back up across the WAN. We're wondering if we can avoid having to buy a separate TSM server and just put a small library in Phoenix that would run LAN-free, with IP robot controller that talks to the TSM server in Boise. Conceptually, can it work? 2) What do you know about/think of Scalar 24 libraries, specifically for LAN-free work? The small library we are looking at is a Scalar 24 from Adic. I've never actually seen one, but the brochures talk about LAN-free connections. If the remote use concept is possible, will this library work? Thanks, Kai.
