Re: setup library client manager LAN

The server-to-server communications is via LAN.  Each TSM server has a
server definition of the other server. The actual tape devices are defined
on each system that can see them. How each server references them is based
on the path definitions on the library managing server. For example, on my
SERVER  A, 3592 drive A is known as /dev/rmt14 while on SERVER B, this
same drive appears as /dev/rmt15.

Re: [ADSM-L] setup library client manager LAN






Zoltan,

In my setup the TSM server B does not have access to the library of TSM
server A through the SAN.

But I would like to sent the TSM database backup from server B to the
library owned and used by TSM server A.

By server-to-server communication between the 2 TSM servers and a library
manager on TSM server A and a library client on TSM server B.

Regards,
Kurt

If I understand you correctly, the answer is yes and I do this daily.

I have 3-tape libraries (1-3493 2-3583) and they are shared by all 4-TSM
servers (2-AIX and 2-Linux) across our SAN.

1-AIX server is the Library Manager for the 3494-ATL and the other AIX
server is the LM for the 2-3583 libraries.

Now that we have our new 3592E05 drives installed in the 3494, they are
used exclusively by the AIX TSM server that owns the 2-LTO libraries
(since the LTO libraries are so problematic and constantly fail - we are
phasing out their usage to just offsite copies), not the AIX server that
owns/manages the 3494, via IP connection.

All traffic is across the SAN. The various servers intercommunication to
juggle the resources. For instance, server A will ask server B for a
drives and scratch tape.  Once server B finished that part, it turns
control over to server A, who then sends the data over the SAN and tracks
the tapes it uses, in it's own database. Server B volhist shows the tape
as being in "REMOTE" status, i.e. used by another server.

[ADSM-L] setup library client manager LAN






Hello,



I've got a question about the setup of a library client and manager. Both
TSM servers are of the version 5.3.2 and run on AIX.



* The library manager would run on TSM server A that has access to the
library across the SAN.

* The library client would run on TSM server B and has no access to the
library of TSM server A across the SAN, the TSM server B has it's own
library.



Is it possible to send backups on TSM server B to the library on TSM
server
A. The backup would then go over the LAN.



In the admin guide I only find a discussion about 'Configuring SCSI
libraries shared among servers on a SAN'. Nothing is found about sharing a
library across the LAN. Is such a setup possible at all?



Thanks in advance for the responses.



Best regards,

Kurt
