Page 15: General Information
General Information This manual describes the SCSI Media Changer (SMC) Command set for Oracle's StorageTek SL150 Modular Tape Library System. The SL150 library uses designated tape drives as the interface to the library or partition. The bridged tape drive determines the destination for commands based on the Logical Unit Number (LUN) that is sent with the command: •...
Page 16: The Fibre Channel Standard
The Fibre Channel Standard 2. Targets: A device (SL150 library tape drives) containing logical units and target ports that receives requests for processing and sends responses to an initiator. The target device for this document is an HP LTO-5, HP LTO-6, IBM LTO-6 or IBM LTO-7 tape drive.

Page 19: Host Application Best Practices
Host Application Best Practices Running on Both Fibre Channel or SAS Ports When the drive has 2 ports, Oracle recommends that Host Application treat the second SL150 drive port as a fail over port. The library may report a CHECK CONDITION to a command received on one port, when the other port is already busy with a library command.
Page 20: Address Installed Drives Only
Drive Element Addressing Mode Configuration • A SCSI MODE SENSE command requesting the Element Address Assignment page will end in Good status. The total number of data transfer elements reported will include empty drive bays. • A SCSI READ ELEMENT STATUS command that includes an empty drive slot will end in Good status.
Page 21: Operation And Configuration Details
Operation and Configuration Details This chapter provides details for operation and configuration that are important while writing host applications. Multiple Initiator Support The library architecture supports multiple initiators with the following details: • Unit - Reserve and Release commands are supported. Persistent Reserve commands are also supported.

Page 29: Scsi Command Status
SCSI Command Status SCSI Command Status Good Good status (00h) indicates that the device successfully completed the command. Check Condition Check Condition status (02h) occurs when any error, unit exception, or abnormal condition generates sense data. The initiator should issue a Request Sense command following a Check Condition status to determine the nature of the error.
Page 30: Initialize Element Status
Initialize Element Status Initialize Element Status The host uses the Initialize Element Status command (07h) to request an inventory of the cartridge tapes held in the library. The library accepts this command for compatibility, but does not perform any action. At power-on the library performs an audit of and maintains the inventory during operations.
Page 31: Initialize Element Status With Range
Initialize Element Status With Range Initialize Element Status With Range The Initialize Element Status With Range command (37h and E7h) is a request from the host to perform an inventory of a portion of the cartridge tapes within the library. The library accepts this command for compatibility but does not perform any action.

Page 249: Partitioning Overview
Partitioning Overview The SL150 library can be partitioned into a maximum of eight distinct sections. Briefly stated, this means that instead of one library—with all its cartridge slots, tape drives, and mailslots—being a single entity, the library and these components can now be divided into sections or partitions.
Page 250: Partitioning-Feature
Partitioning—General Partitioning—Feature The SL150 library supports one to eight partitions. The customer has the choice of a non-partitioned library or a library with one to eight partitions. When a partitioned library is desired, the administrator enables the Library Partitioning option and adds the desired number of partitions. The administrator configures each partition with the following: •...
