ACSLS, SCSI and 349X Tape Library Sharing

When Tivoli Storage Manager servers share an ACSLS, SCSI tape, or 349X storage device using a library manager and library clients, one server, the library manager, owns and controls the tape library device. The library manager operations include checking volumes into and out of the library, labeling volumes, mounting and dismounting volumes, auditing volumes, and tracking an inventory of library contents. The storage agents, along with other Tivoli Storage Manager servers that share this library, are considered library clients. As a library client, the storage agent is able to store data and request drives, tapes, and volumes.

When the Tivoli Storage Manager server (data manager server) is also the library manager for the devices where data is stored by the storage agent, then the storage agent communicates requests to this Tivoli Storage Manager server. When the Tivoli Storage Manager server (data manager server) is another library client, then the storage agent communicates requests for itself or the metadata server directly to the library manager.

Note that when using a shared ACSLS library, the library manager must be a Tivoli Storage Manager server on AIX, Solaris, or Windows.

A library client requests shared library resources, such as drives or media, from the library manager, but uses the resources independently. The library manager coordinates the access to these resources. Data moves over the SAN between the storage device and either the library manager or the library client. Either the library manager or any library client can manage the LAN-free movement of client data as long as the client system includes a storage agent.

In this library-sharing environment, the most important relationship is the one between the server and the storage agent. The server, working in conjunction with the storage agent, manages the storage hierarchy. The server could be a library client or library manager, and it is responsible for:

vMigrations

vExpiration of files based on policy information

vReclamation of free space on volumes and consolidation of the volumes

vDisaster recovery

The storage agent contributes information to the storage hierarchy through various operations, but this role is independent of the library sharing role.

The library manager and library client configurations are represented in Figure 3 on page 7 and Figure 4 on page 8.
