4.6.11. T9840D and T10000A Applicable
The T9840D and T10000A support AES256 encryption supported by the SUN Crypto Key
Management Station (KMS). Currently all devices of a particular type must be encryption
capable or have encryption disabled.
The T9840D and T10000A tape devices are supported by all Dorado systems.
BUFFIL (buffering of tape file marks) is supported by T9840D and T10000A.
BUFTAP (Tape Mark Buffering Phase II) is supported by T9840D and T10000A .
The Media Manager ILES (MMGR) and the Exec Media Manager code are modified to
support the T9840D and T10000A tape devices. New bits are added in the TIF record
and MMI work buffer to represent the T9840D and T10000A devices and the new
density values. With the addition of the T9840D and T10000A, these devices make up
the eighth and ninth media types (these types are, open-reel, 18/36-track, DLT,
LTO3-HP/LTO4-HP, T9840A, CTS9940, U9840C, T9840D, and T10000A cartridge). The
existing media is represented by open-reel, half-inch cartridge, T9840A, CTS9940B,
U9840C, T9840D, DLT, LTO3-HP/LTO4-HP, and T10000A cartridge. This design
addresses nine media types by having MMGR return different statuses for each media
type when a media incompatibility is found.
Table 4–5 provides a summary of the features that are supported within the Exec for
T9840D and T10000A tape devices (Y=yes, the feature/capability is supported; N=no,
the feature/capability is not supported; NA=not applicable, the feature/capability does not
apply because it’s not supported by the vendor)
