indicates either Yes (xxxxxx) , where xxxxxx indicates the maximum number
of logical volumes that can be inserted into the VTS, or No . The expansion
occurs in increments of 50,000, so possible values of xxxxxx are limited to
300000, 350000, 400000, 450000, or 500000.
Secure Data Erase Capable
Indicates Yes if the VTS or TS7700 Virtualization Engine has the Secure
Data Erase option enabled or No if it has not. If enabled, this option
ensures that expired logical volume data on a reclaimed physical volume
cannot be recovered by any reasonable means, such as reading in a
standalone tape device. See “Stacked Volume Pool Properties” on page 266
for more information.
Larger Logical Volume Capable
Indicates whether or not the VTS or TS7700 Virtualization Engine has the
Larger Logical Volume option enabled. If enabled, this option allows the
operator to select the size of the VTS’s logical volumes from a set of
defined sizes via the data class construct. It indicates either Yes (xxxx) ,
where xxxx indicates in megabytes the maximum logical volume size
allowed for the VTS (either 1000 MB, 2000 MB, or 4000 MB), or No . See
“Manage Data Classes” on page 264 for more information.
JB Media Capable
Indicates Yes if the VTS or TS7700 Virtualization Engine has the JB Media
option enabled or No if it has not.
Encryption Capable
Indicates Yes if the VTS or TS7700 Virtualization Engine is encryption
capable.
Library Emulation Capable
Indicates Yes if the VTS or TS7700 Virtualization Engine is library
emulation capable.
Note: For a TS7700 Virtualization Engine that is library emulation capable,
all the VE-related functions that used to be executed from the
Library Manager are now executed from the VE’s Management
Interface (MI). This includes logical mounts. For this reason, the
logical devices are marked as unavailable along with their associated
VCU ports. The Library Manager will only manage the physical
drives for a VE that is library emulation capable.
The VTS Status window has the following push buttons:
OK Closes the VTS Status window.
Help Provides help about the VTS Status window.
VTS Active Data
Notes:
v This window is not used with the TS7700 Virtualization Engine.
v You can view VTS active data from the Specialist (see “Specialist
Features and Functions” on page 396).
The VTS Active Data window (Figure 99 on page 173) displays a graph showing
the amount of active data, amount of free storage, maximum active data, and a
free storage alarm level for the stacked volumes in a VTS. The data stored on
stacked volumes is from the tape volume cache and may be compressed when the
VTS has the
