cartridge through the convenience I/O station for storage outside the 3494 Tape
Library or movement to another 3494 Tape Library to be imported into a VTS.
Host console messages provide status on progress and success of the Export
operation.
Note:
1. Exported Stacked Volumes created on 3590 B1A Tape Drives that are
associated with a VTS can be imported into VTS configurations that have
3590 B1A Tape Drives, 3590 E1A Tape Drives, or 3590 H1A Tape Drives.
Exported Stacked Volumes created on 3590 E1A Tape Drives or 3590
H1A Tape Drives cannot be imported using 3590 B1A Tape Drives.
2.
Exported Stacked Volumes created on 3590 B1A Tape Drives or 3590 E1A
Tape Drives can be imported into 3590 H1A Tape Drives. However,
Exported Stacked Volumes created on 3590 H1A Tape Drives cannot be
imported into 3590 B1A Tape Drives or 3590 E1A Tape Drives.
3. Exported Stacked Volumes created on 3592 J1A Tape Drives can be only
be imported into other 3592 J1A Tape Drives.
4. Exported Stacked Volumes created on 3592 J1A Tape Drives can be only
be imported into 3592 E05 Tape Drives and other 3592 J1A Tape Drives.
5. Exported Stacked Volumes created on 3592 E05 Tape Drives can be only
be imported into other 3592 E05 Tape Drives.
Advanced Policy Management
Note:
Advanced Policy Management is standard on the TS7700 Virtualization
Engine. No feature codes are required.
FC 4001-4004, Advanced Policy Management, gives you more control over how
logical and physical volumes are managed within the subsystem so you can better
utilize the resources of a VTS. Advanced Policy Management allows you to do the
following:
v Volume Pooling: Allows you to control the grouping of virtual volumes together
on 3590 or 3592 media. Pooling can be controlled by DFSMS Automatic Class
Selection or by storage administrator-defined defaults. The following items are
defined by pooling:
– Data reclamation policies
– Secure data erase policy
v Local Tape Volume Duplexing: Allows you to control the selective creation of a
second tape copy of virtual volumes in a different storage pool from the primary
copy. Dual copy is controlled by DFSMS Automatic Class Selection or by storage
administrator-defined defaults.
v
Peer-to-Peer Selective Copy Mode: Allows you to control the copy mode for
each logical volume.
v Tape Volume Cache Management: Allows you to manage the residency of
logical volumes in the Tape Volume Cache to maximize the probability of the
needed volumes being resident in the Tape Volume Cache when requested.
v Peer-to-Peer Selective Dual Copy: Allows you to select which VTS in a PtP VTS
configuration shall be the I/O VTS and to choose whether or not written data
shall be copied to a second (that is, non-I/O) VTS.
v
Larger Logical Volumes: Allows you to select among the following available
logical volume sizes: Default media type (either 400 MB or 800 MB), 1000 MB,
2000 MB, or 4000 MB.
