Configuring Your Library
file:///T|/htdocs/stor-sys/ML6000/en/html/ch04.htm[9/17/2012 1:49:29 PM]
A partition can be deleted when it is no longer needed or in preparation for removing a module from the library.
Administrators can delete one partition at a time.
Unload all tape drives and export all cartridges assigned to the partition that is to be deleted. After exporting the cartridges,
remove them from the I/E station. For more information, see
Unloading Tape Drives and Exporting Media.
Details about deleting partitions include the following:
• After a partition is deleted, its resources (for example, tape drives and slots) become available and can be reassigned
to new or existing partitions.
• Deleting a partition does not delete users assigned to that partition. However, if these users are not assigned to other
partitions, they will not be able to perform library operations. See
Changing Partition Access.
• Because partitions may extend across the library's physical modules and share resources, the library will report errors
if you permanently remove or replace a module in your library without first deleting or modifying partitions and
modifying shared resources such as cleaning slots and I/E slots. See
Preparing to Remove or Replace a Module for
detailed instructions on preparing your library for the permanent removal or replacement of a module.
Note: You may need to modify settings in your host application as a result of deleting a partition. See your host
application documentation.
The paths to open the appropriate screens are as follows:
• From the Web client, select Setup > Partitions.
• From the operator panel, select Setup > Partition Mgmt.
Changing Partition Access
An administrator can control which partitions a specified user can access by modifying the user's account. Also, any user
assigned to a partition that has been deleted can be reassigned to other partitions.
To change partition access, you must provide the following information:
• Password — A unique password that can be viewed and modified by the administrator.
• Privilege Level — Determines the user's access privileges. See
User Privileges for more information on user privilege
levels.
• Partition Access — the partitions to which the user has access.
The paths to open the appropriate screens are as follows:
• From the Web client, select Setup > User Management > User Accounts.
• From the operator panel, select Setup > User Mgmt > Modify User.
Taking a Partition Online or Offline
This topic focuses on using the library user interface to change partition mode. Changing a partition mode using the library
user interface may affect your host application. See your host application documentation for more information.
There are two partition modes: online and offline.
• Online — SCSI hosts control the partition. In this mode, all host application SCSI commands are processed.
• Offline — SCSI hosts cannot control the partition. In this mode, library operations can be performed via the operator
panel or Web client.
When you are changing the partition mode, be aware of the following:
• When you access the Change Partition Mode screens, you will see only partitions to which you have been given
access.
• The Online/Offline buttons toggle between modes.
• If a partition is in use, the Online/Offline button is grayed out.
Note: Some maintenance activities require that the entire library be taken offline. To take the library offline, change
