Establishing network connections

Edit online

You must establish network connections from the client, with the storage agent installed, to the z/OS system where the IBM Storage Protect for z/OS Media is installed.

For details, levels, and models of hardware and software, see http://www.ibm.com/support/entry/portal/Overview/Software/Tivoli/Tivoli_Storage_Manager.

Figure 1. Network connection between a storage agent, a IBM Storage Protect server, and a z/OS media server. Client data is transferred between the storage agent and the z/OS media server.
The following systems are connected to a LAN: a IBM Storage Protect backup-archive client, with a storage agent attached; a IBM Storage Protect server; and a z/OS media server. A z/OS FICON tape library is attached to the z/OS media server.
The IBM Storage Protect server system, the z/OS media server system, and the client systems along with appropriate storage devices are all attached to a LAN. You must define the following paths to establish network connections:
  • Storage agent to the z/OS media server
  • Backup-archive client to the IBM Storage Protect server
  • IBM Storage Protect server to the z/OS media server
Figure 2. Network connection between a storage agent, a IBM Storage Protect server, and a z/OS media server, using two LANs.
The following systems are connected to two LANs: a IBM Storage Protect backup-archive client, with a storage agent attached; a IBM Storage Protect server; and a z/OS media server. A z/OS FICON tape library is attached to the z/OS media server. The backup-archive client, with the storage agent attached and the z/OS media server are also attached to LAN 1. Client data is transferred between the storage agent and the z/OS media server through LAN 1. Metadata is transferred from the storage agent to the z/OS media server via a IBM Storage Protect server, through LAN 2. The IBM Storage Protect backup-archive client HLADDRESS is 9.6.5.41; the backup-archive client to server path is 9.6.5.4; the HLADDRESS path from the storage agent to z/OS media server is 9.8.7.6; and the IBM Storage Protect server to the z/OS media server path is 192.0.2.24.

You can use multiple network connections to establish a connection to a z/OS media server. For example, if you use a high-bandwidth connection, you can use multiple network connections to access a z/OS media server.

Client data is transferred between the storage agent and the z/OS media server server through LAN 1. Metadata is transferred from the storage agent to the IBM Storage Protect server, through LAN 2.
