■ Relabel the volume for immediate reuse.

■ Export the volume to offsite storage as a historical record of file changes. You

can use standard UNIX utilities to restore previous versions of files from

expired archive copies.

The recycling process is transparent to end users. For more information about

recycling, see “Recycling” on page 149.

Storage Devices

The Sun StorageTek SAM environment supports a wide variety of tape storage and

magneto-optical devices. The automated libraries that Sun StorageTek SAM supports

can be divided into the following groups, depending on how they are attached to the

environment:

■ A direct attachment. A direct attached library is connected directly to the host

system using a Small Computer System Interface (SCSI). This can be either a

direct connection or a Fibre Channel connection. For example, a direct attachment

is used for Sun StorageTek libraries. The Sun StorageTek SAM system controls

these libraries directly using the SCSI standard for automated libraries.

■ A network attachment. The Sun StorageTek SAM software can be configured as a

client of the library’s host system. The network attached libraries include some of

the StorageTek, ADIC/Grau, IBM, and Sony libraries. These libraries use a

software package supplied by the vendor. In these cases, the Sun StorageTek SAM

software interfaces with the vendor software, using a daemon specifically

designed for the automated library.

TABLE 1-1 shows the daemons specific to various automated libraries.

TABLE 1-1 Automated Library Daemons

Daemon Description

sam-robotsd Monitors the execution of robot control daemons. The

sam-robotsd daemon is started automatically by the sam-amld

daemon.

sam-genericd Controls direct attached libraries and media changers. Also controls

ADIC libraries through the DAS interface.

sam-stkd Controls the StorageTek media changers through the ACSAPI

interface.

sam-ibm3494d Controls the IBM 3494 tape libraries through the lmcpd interface.

sam-sonyd Controls the Sony network attached automated libraries through the

DZC-8000S interface.
