## 6.1 Setting up the TS7700 

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. 

## 6.1.1 TS4500/TS3500 tape library definitions 

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 

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. 

GLYPH<SM590000> Defining control path drives 

Each TS7700T requires the definition of four tape drives (among installed drives) as control path drives.
