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.
