Chapter 9 Running Your Library

Performing Media Operations

Dell PowerVault ML6000 User’s Guide 176

You need to provide the following information in the Unload Drive

screens to unload tape cartridges from tape drives:

• Partition — The partition containing the tape drive that you want to

unload. The screens include information about the partition mode

(online or offline).

• Tape drive — The tape drive that contains the cartridge that you want

to unload.

The paths to open the appropriate screens are as follows:

• From the Web client, select Operations > Drive > Unload.

• From the operator panel, select Operations > Unload Drive.

For step-by-step procedures, see the library’s online Help. To access the

online Help system, click the Help icon at the top right of the Web client or

operator panel user interface.

Taking a Tape Drive

Online or Offline 9

There are two tape drive modes: online and offline.

• Online — Tape drive is available for use. This is the normal operating

mode for the tape drive.

• Offline — Tape drive is offline to the host application and is not

available for cartridge load and unload (move) operations initiated

by the host application, but it remains available for Web client or

operator panel initiated move commands.

Note: If the operation does not complete successfully, the

partition remains offline until you turn it back online

manually or restart the library (see Taking a Partition

Online or Offline on page 78).

Note: You can sort the list of tape drives by clicking on columns with

bold headings. For example, selecting the Location column

heading sorts the list by location coordinates.

Note: If a cartridge is already in the tape drive when you take

the tape drive offline, then the host can still read and write

data on the tape.
