Automatically Creating Partitions; Manually Creating Partitions - Dell PowerVault ML6010 Troubleshooting Manual

Configuring Your Library
• Administrators can create, modify, delete, and control access to all partitions. Users can be given access to only
certain partitions and denied access to others.
• Partition names are limited to 12 lower-case alphanumeric characters and underscores (_).
• The maximum number of partitions that can be created is equal to the number of tape drives in the library.
• At minimum, a partition consists of one tape drive and one slot. The tape drive or slot cannot be shared with another
partition.
• I/E station slots are shared between all partitions. Partitions take temporary ownership of I/E station slots when
importing or exporting tape cartridges.
Caution:
Before permanently removing a 9U Library Expansion Module from your library, you need to perform a set
of configuration operations that includes deleting all partitions. See
Expansion Module.

Automatically Creating Partitions

At any time after the initial configuration of the library, administrators can add to the number of existing partitions by using
the automatic partitioning process. Automatic partitioning assigns available library resources proportionately among the
partitions, grouping tape drives according to their interface type (SCSI, FC, or SAS) and tape drive media type.
The library must contain at least one unassigned tape drive and one unassigned slot to automatically create a partition. If no
unassigned tape drives or slots exist, you must modify or delete one or more partitions to free up resources. For more
information, see Modifying Partitions
On the Automatically Create Partitions screen, you can select the number of partitions to create, from a minimum of the
default specified by the library to a maximum that equals the number of unassigned tape drives in your library.
The default number of partitions created is the number of distinct tape drive interface/media type combinations of the tape
drives that are not currently assigned to a partition. For example:
• If your library contained two tape drives, an FC IBM LTO-3 and an FC IBM LTO 4, two partitions would be created
because although they have the same interface type, they have different media types (LTO-3 and LTO-4).
The default number of partitions created is also the minimum number of partitions you can create. If you are using the Setup
Wizard, you may choose to create zero partitions now and instead create them later using the web client or operator panel.
When the library automatically creates partitions, it creates control paths. See
the default control paths and how to change them.
By default, the library applies the Standard barcode format to each partition. You can change this setting by modifying the
partitions after it has been created. For information on modifying partitions, see
Note:
This operation cannot be performed concurrently by multiple administrators logged in from different locations.
You can access the screen, but you cannot apply changes while another administrator is performing the same
operation.
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 > Create Partition.

Manually Creating Partitions

Using the Web client, administrators can manually create additional partitions any time after the initial configuration of the
library. The maximum number of partitions that can be created is equal to the number of drives in the library.
The library must contain at least one unassigned tape drive and slot to create a partition. If no tape drives or slots are
available, you must modify or delete an existing partition to free up resources. For more information, see
and Deleting Partitions. When you manually create partitions, the library creates control paths. See
Paths for a description of the default control paths and how to change them.
When creating partitions manually, you need to provide the following information:
