ACL Operational Characteristics
3.1 Introduction
This section describes ACL capabilities and behavior. You should be familiar with the
information in this section before using the ACL utilities or libacl API functions.
3.2 ACL Configuration
The following paragraphs describe the ACL configuration.
3.2.1 Addressable Elements
Each ACL element that can contain a tape cartridge is assigned both a SCSI address and a
location name.
libacl functions recognize the element addresses listed below. You can use aclGetElemData()
to retrieve complete element counts and starting addresses from the ACL, or
aclAuditLibrary() to retrieve the addresses of all elements in the ACL.
The ACL utilities recognize both the element addresses and the location names listed below.
You can use acl_audit_library to retrieve the names and addresses of all elements in the ACL.
The DST 412 ACL can move a tape cartridge from a storage bin to the tape drive, or from the
tape drive to a storage bin. DST 712 and DST 812 ACLs can move a tape cartridge to or from
any element. See “Configuration Parameters” on page 3-6 for information on configuration
parameter settings that affect tape cartridge movement.
