The TS3500 Tape Library with the Advanced Library Management System (ALMS)
enabled can have a mix of both LTO and 3592 tape drives supporting various
encryption configurations across several logical libraries. The rules for setting up
encryption differ based on whether you use Library-Managed Encryption (LME),
System-Managed Encryption (SME), or Application-Managed Encryption (AME).
Table 69 presents an overview of these rules.

(for libraries with ALMS)
LTO Tape Drives
Note: Feature code 1604 is required to enable encryption
on LTO Ultrium 4 and newer tape drives if using LME
or SME.
v
Encryption can be enabled with a mix of both
encryption-capable (LTO Ultrium 4 and later) drives
and drives that are not encryption capable (LTO
Ultirum 2 and Ultrium 3).
v
Any LTO Ultrium 4 and later drives in the library can
be encryption enabled with LME, AME, or SME,
however FC 1604 is required for LME and SME.
v
When using LME with Ultrium 5 and later tape drives,
the Tivoli Key Lifecycle Manger (TKLM) is required as
the key manager.
3592 Tape Drives
v If using LME or AME, all drives in a logical library
must be encryption capable for encryption to be
enabled.
v
If using SME in a library with ALMS, it is possible for
the library to consist of a mix of encryption-capable
drives and drives that are not encryption capable.
Mixed (LTO and 3592) Drives
v
Encryption can be enabled only on the 3592 tape
drives, only on the LTO Ultrium tape drives, or on
both.
v If you want to enable encryption only on 3592 drives,
follow the rules above for 3592 libraries.
v
If you want to enable encryption only on LTO drives,
follow the rules above for LTO libraries.
v If you want to enable encryption on both, adhere to
the rules above for each, respectively.
Note:
v
In order for encryption to be supported in the TS3500 Tape Library, the rules
presented in Table 69 must be followed. Failure to adhere to these rules may
result in problems when enabling encryption.
v
The following feature codes are required when setting up encryption in the
TS3500 Tape Library.
– FC 9900, Encryption Configuration
– FC 1604, Transparent LTO Encryption (required for LTO Ultrium 4 and newer
tape drives if using LME or SME)
– FC 1690, Advanced Library Management System
v
