Draft Document for Review February 7, 2020 3:15 pm 8464ch06_HW Implement.fm 6.1 Setting up the TS7700  6.1.1 TS4500/TS3500 tape library definitions  The following sections describe the implementation and installation tasks to set up the  TS7700. Specific names are used in this chapter if a task applies to only one model among  supported models because slight differences exist between the TS7770C/TS7760C  (TS7700C cloud storage tier configurations), TS7770D/TS7760D (TS7700D disk-only  configurations), and TS7770T/TS7760T (TS7700T tape-attached configurations). For example, because the TS7700D and TS7700C do not include a tape library that is  attached to them, the implementation steps that are related to a physical IBM  TS4500/TS3500 tape library do not apply to them. However, you can install the TS7760T or  TS7770T with your existing or new TS4500/TS3500 tape library to serve as the physical  back-end tape library.  The section describes implementing TS7700T that is attached to a TS4500/TS3500 tape  library. If your TS7700 does not have an associated tape library (such as the TS7700D and  TS7700C), see 6.1.4, “TS7700 definitions” on page 229. Your IBM Service Support Representative (IBM SSR) installs the TS7700T hardware, its  associated tape library, and the frames. This installation does not require your involvement  other than the necessary planning. For more information, see Chapter 4, “Preinstallation  planning and sizin g ” on page 131.  Clarification:  The steps that are described in this section relate to the configuration of a  new or existing IBM TS4500/TS3500 tape library with all of the required features installed,  such as Advanced Library Management System (ALMS).  If you are attaching to an IBM physical tape library that is also attached to Open Systems  hosts or IBM Z hosts, see  IBM TS3500 Tape Library with System z Attachment A Practical  Guide to Enterprise Tape Drives and TS3500 Tape Automation , SG24-6789, or  IBM  TS4500 R6 Tape Library Guide , SG24-8235 for more information about extra steps that  might be required. The following tasks apply to TS4500/TS3500 library definition (for more information about the  procedure, see 9.5.1, “Tape library with the TS7700T cluster” on page 524): GLYPH<SM590000> Defining a logical library: – Ensuring that ALMS is enabled  – Creating a logical library with ALMS – Setting the maximum cartridges for the logical library GLYPH<SM590000> Adding drives to the logical library GLYPH<SM590000> Defining control path drives Each TS7700T is associated with only one logical library in the physical library, and each  logical library can be associated with only one TS7700. A TS7700T requires a minimum of  four installed tape drives to be operational, and a maximum of 16 can be used. Each TS7700T requires the definition of four tape drives (among installed drives) as  control path drives. Chapter 6. IBM TS7700 implementation  227
