Once again, I am looking for help/confirmation/suggestions on how to make this seemingly impossible configuration of Library Manager/Library Server/TSM server behind firewall.
This is what we are attempting----sorry about the repeats for those folks who have been living through this mess, with me ! 1. 3494-ATL with FC drives 2. 1-TSM AIX server acting as the Library Manager. Attached to SAN. 3. 1-TSM Linux server acting as a Library Client. Attached to SAN. Here are the conditions/requirements: a. The AIX server and the 3494 are on the same, private subnet. The AIX server is dual-homed with another nic that is accessible from the outside. b. The Linux server is behind a firewall/nat on a completely different network. Dual-homing IS NOT ALLOWED. We have been able to configure a static IP address for when this server goes out the firewall. Issue: The Linux server needs to use the 3590-FC drives in the 3494-ATL. Problem: Server-to-server communications is not constant or kept open. While the Linux server can contact and initiate communications with the AIX server, the AIX server can not initiate a communications session with the Linux server.....thus the AIX server can't manage the access to the tape library and drives. How can we resolve this ? From my point of view, I can see how to do this without either another connection to the ATL (again, not allowed as dual-homed.....can the ATL have multiple IP addresses, one behind the firewall, the other not ???) or another ATL just for the Linux server (not do-able - no $$$$$). We are open to any and all suggestions.
