Library Manager/Client & Firewall - the sage continues
2004-05-20 16:07:03
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.
