Notes: To use encryption, all drives that are associated with the TS7740, TS7720 Tape Attach, or TS7760 Tape Attach must be encryption-capable and -enabled. Encryption is not supported on 3592 J1A tape drives.

Restrictions for use with TS1140 Tape Drives

Note: Throughout this section, the term TS7700 refers to either the TS7740, the TS7720 Tape Attach, or the TS7760 Tape Attach.

TS1140 Tape Drives are supported in new TS7700 orders from manufacturing, and with existing TS7700s attached to a library. The following additional media restrictions apply when a library attached to a TS7740, TS7720 Tape Attach, or TS7760 Tape Attach contains TS1140 Tape Drives:

JA and JJ media are supported for read-only operations. If JA or JJ media exist or are installed in a library that contains TS1140 Tape Drives, then:
- Online processing succeeds but all JA and JJ media is marked read-only for reclamation
  Note: One main purpose of reclamation is to increase the number of available physical scratch volumes in the pool. When TS1140 Tape Drives are installed, JJ and JA media reclamation reduces, instead of increases, the number of available scratch volumes. Reclamation of a JA or JJ cartridge does not occur if the TS7700 is in a low scratch state (fewer than 15 available scratch volumes) for the pool. For example, if borrowing is enabled and there are JA physical volumes to be reclaimed in pool 1, the sum of available scratch tapes in pool 1 and the common scratch pool 0 must be greater than 15 for reclamation of the JA physical volumes to occur. If the system contains TS1140 or TS1150 tape drives, the system requires at least 15 scratch physical volumes to run reclamation for sunset media.
- JA and JJ media can be ejected by using the TS7700 Management Interface once their active data is reclaimed onto newer media
Note: JA and JJ media should not be inserted if the volumes do not exist in the TS7700 database.
If JB media contains data that is written in E05 format, it is marked full and is supported as READ-ONLY data. Once the data is reclaimed or written in E06 or E07 format, it is supported for READ-WRITE operations. The IBM Encryption Key Manager is not supported for use with TS1140 Tape Drives. If encryption is used, either the Tivoli Key Lifecycle Manager (TKLM) or the IBM Security Key Lifecycle Manager (ISKLM) must be used.
3592 EU6 Tape Drives cannot be converted to TS1140 Tape Drives.

Restrictions for use with TS1150 Tape Drives (Homogeneous Configuration)

Note: Throughout this section, the term TS7700 refers to either the TS7740, the TS7720 Tape Attach, or the TS7760 Tape Attach.

TS1150 Tape Drives are supported in new TS7700 orders from manufacturing, and with existing TS7700s attached to a library. The following additional media restrictions apply when a library attached to a TS7740, TS7720 Tape Attach, or TS7760 Tape Attach contains TS1150 Tape Drives:

JA, JJ, and JB media are not supported for read-only operations.
The IBM Encryption Key Manager is not supported for use with 3592 E08 Tape Drive. If encryption is used, either the Tivoli Key Lifecycle Manager (TKLM) or the IBM Security Key Lifecycle Manager (ISKLM) must be used.
TS1140 Tape Drives cannot be converted to TS1150 Tape Drives.

Restrictions for use with TS1150 Tape Drives (Heterogeneous Configuration)

Note: Throughout this section, the term TS7700 refers to either the TS7740, the TS7720 Tape Attach, or the TS7760 Tape Attach.

TS1150 Tape Drives can be intermixed with one other TS11xx drive type in a library attached to a TS7740, TS7720 Tape Attach, or TS7760 Tape Attach.
JA, JJ, and JB media are supported for read-only operations. If JA, JJ, or JB media exist or are installed in a library that contains TS1150 Tape Drives, then:
- Online processing succeeds but all JA, JJ, JB media is marked read-only for reclamation
  Note: One main purpose of reclamation is to increase the number of available physical scratch volumes in the pool. When TS1150 Tape Drives are installed, JJ, JA, and JB media reclamation reduces, instead of increases, the number of available scratch volumes. Reclamation of a JA, JJ, or JB cartridge does not occur if the TS7700 is in a low scratch state (fewer than 15 available scratch volumes) for the pool. For example, if borrowing is enabled and there are JA physical volumes to be reclaimed in pool 1, the sum of available scratch tapes in pool 1 and the common scratch pool 0 must be greater than 15 for reclamation of the JA physical volumes to occur. If the system contains TS1140 or TS1150 tape drives, the system requires at least 15 scratch physical volumes to run reclamation for sunset media.

Note: JA, JJ, and JB media should not be inserted if the volumes do not exist in the TS7700 database.
The IBM Encryption Key Manager is not supported for use with TS1150 Tape Drive. If encryption is used, either the Tivoli Key Lifecycle Manager (TKLM) or the IBM Security Key Lifecycle Manager (ISKLM) must be used.
TS1140 Tape Drives cannot be converted to TS1150 Tape Drives.

Native capacity of tape drives

The TS7700 uses the native capacity of 3592 Tape Drives with the following restrictions:

Only a TS1120 Tape Drive can emulate a 3592 J1A Tape Drive. When the TS1120 Tape Drive is in 3592 J1A emulation mode, data is written in the 3592 J1A recording format. The TS7700 supports a mix of TS1120 Tape Drives in 3592 J1A emulation mode and 3592 J1A Tape Drives.
The combination of encryption-capable and non-encryption-capable drives is not supported. Model 3592 J1A Tape Drives and TS1120 Tape Drives without hardware encryption modules are not encryption capable. All TS1120 Tape Drives with the hardware encryption modules, TS1130, TS1140, and TS1150 Tape Drives are encryption capable.
When the TS7700 is online and tape drives are running in native E05 mode, 3592 J1A Tape Drives cannot be added to the configuration.
When physical volumes are written in native E05 mode, the TS7700 can no longer operate in 3592 J1A emulation mode.
Note: If the TS7700 is returned to 3592 J1A emulation mode after physical volumes are written in native E05 mode, the TS7700 cannot be returned to an online status.

TS1120 Tape Drives operate in native E05 mode or in 3592 J1A emulation mode. However, all 3592 Tape Drives associated with the TS7700 must be TS1120 Tape Drives in order for the TS1120 Tape Drives to operate in native E05 mode. To use TS1120 Tape Drives in native E05 mode, the drives must be set to E05 native mode. If you intend to use TS1120 Tape Drives in native E05 mode, the minimum microcode levels are 8.0.1.xx for the TS7700 and 534.2x for the Library Manager. Ask your next level of support to receive the most current levels of microcode.
