Device commands, 3 element status – HP Data Protector Express Basic-Software User Manual
Page 40

Status
The Status page displays the current status information for the selected device. For example,
it shows the current operation, if any, being performed on the device. It also shows the last time a
write and read was done on the device.
TIP:
Data Protector Express tracks the contents of devices and libraries while it is running. However, there may
be times when someone changes media in a device or a library when Data Protector Express is not
running. The Probably qualification on element status indicates that Data Protector Express has restarted
and is operating under its previous understanding of the current element status but that the understanding
may be incorrect. When Probably appears before an element status, the element’s actual status will
be determined the next time the element is used.
Table 3 Element status
Valid
The slot is known to hold media that is in the current catalog.
Probably Valid
The slot held valid media previously. Data Protector Express verifies that the media is valid
before using it. When you exit and restart Data Protector Express, media marked Valid is
reset to Probably Valid.
Invalid
The slot holds media that is definitely not in the current catalog.
Probably Invalid
The slot holds media that may not be in the current catalog. When you exit and restart Data
Protector Express, media marked Invalid is reset to Probably Invalid.
Empty
The slot is either known to be empty or a user changed its status to Empty.
Probably Empty
The slot was empty previously. When you exit and restart Data Protector Express, slots marked
Empty are reset to Probably Empty.
Unknown
The status of the slot is not known, usually because it has not been used yet.
Cleaning Tape
A user marked the slot as holding a cleaning cartridge. The number of remaining cleaning
cycles also appears. Data Protector Express does not verify that a cleaning cartridge was, in
fact, inserted into this slot.
Probably Cleaning TapeThe slot previously contained a cleaning tape. When you exit and restart Data Protector Express,
slots marked Cleaning Tape are reset to Probably Cleaning Tape.
Reserved
The slot was disabled by a user. Data Protector Express will ignore it during any job. You can
only change the status of a reserved slot. Data Protector Express changes the status of all
other slots during normal operations.
Configuration
You can set the size of the I/O buffer to be used for this device. Usually, you do not
need to change the default. However, for some devices, you may be able to increase performance by
adjusting the size of the I/O buffer.
Diagnostics
The Diagnostics page displays diagnostic information about the device. This includes
information about the driver, the inquiry information, device statistics, and buffer statistics. Often this
information can assist in troubleshooting problems. The diagnostics can be saved to a file or emailed
directly from the diagnostic screen.
Device Commands
There are several physical operations that can be performed on a selected device. Some of these
operations affect the device itself, while others affect the current media in the device.
