DESCRIPTION

The Ampex DST/DIS SCSI Automated Cartridge Library libacl C-Library functions comprise

an application programming interface that provides access to the ACL device driver and also

to native SCSI passthru device driver interfaces. libacl functions provide the means to:

• check whether the ACL is ready to accept commands.

• update the ACL internal database and check element status.

• check or change ACL conﬁguration parameter settings.

• retrieve error/event logs, static logs, and SCSI sense data.

• get vendor, product, software version, and software release information.

• control the ACL cartridge handling system (CHS).

• move tape cartridges between speciﬁed locations.

• retrieve ACL operating status.

• reserve and release the ACL.

• issue generic SCSI commands.

APPLICABILITY

Unless otherwise noted, the information in the libacl API manual pages applies to all DST and

DIS ACLs. Information unique to speciﬁc ACL models is identiﬁed by series number:

Series Number ACL Model

2XX DIS 220i, DIS 260i, etc.

4XX DST 410, DST 412, etc.

8XX DST 810, DST 812, etc.
