GLYPH<SM590000> Defining the encryption method for the new logical library 

The TS7700T supports only encryption when its attached logical library is configured to use the System-Managed encryption method. 

GLYPH<SM590000> Defining CAPs (Cartridge Assignment Policies) 

Defining CAP policies automates the assignment of physical volumes to the logical library that are associated with the target TS7700T. 

GLYPH<SM590000> Inserting TS7770T or TS7760T physical volumes into the library 

This task consists on the physical insertion of cartridges to be used by the TS7700. This process can be done by using the I/O station in the tape library, or by opening a tape library enclosure door and directly inserting cartridges into available slots. The inventory is needed only if the door is opened to insert cartridges. 

GLYPH<SM590000> Assigning cartridges in the TS4500/TS3500 tape library to the logical library partition 

This procedure is necessary only if a cartridge was inserted, but a Cartridge Assignment Policy (CAP) was not declared in advance. 

GLYPH<SM590000> Relabeling physical volumes 

This procedure is necessary only if a mismatch exists between the internal and external label of a physical tape cartridge. To correct such a condition, you can use the library request command interface to submit a LI REQ PVOL, <volser>, RELABEL, YES  request against the affected cartridge, which marks it for relabeling the next time that it is written from the beginning of tape. 

Note:  For more information about the Library Request commands and their responses, see IBM TS7700 Library Request Command V5.0, WP101091. 

## 6.1.2 Definitions for TS7700T 

If you use a TS7700C or TS7700D, skip this section and see 6.1.4, “TS7700 definitions” on page 229. For more information about TS7700T procedures, see 9.5.2, “TS7700 definitions” on page 541. 

The following tasks apply only to TS7700T: 

GLYPH<SM590000> Defining VOLSER ranges for physical volumes 

The physical VOLSER ranges in the TS7700T should match the cartridge assignments in the logical library of the attached TS4500/TS3500 

GLYPH<SM590000> Defining physical volume pool properties: 

– Set the reclaim threshold 

– Set up any Inhibit Reclaim schedules, if required 

GLYPH<SM590000> If the TS7700T is required to perform tape encryption (only for machines that have feature code 9900 installed), the following definitions are applicable: 

– Data at rest encryption configuration 

This cluster setting requires the address of the (IBM Security Key Lifecycle Manager (ISKLM) server that is responsible for managing the encryption keys that are used for data that is copied to physical volumes. 

Key exchanges for tape encryption are performed by using the IPP protocol. Starting with microcode R5.0, the TS7700T supports the use of the TLS1.2 protocol to encapsulate IPP traffic to target ISKLM, which requires importing its corresponding server certificate into the TS7700T.
