You can automatically create additional partitions any time after the initial configuration of the library. The library must contain at least one unallocated tape drive and one unallocated slot to automatically create a partition. If no unallocated tape drives or slots exist, you must modify or delete partitions to free resources. For information on modifying partitions, see Modifying Partitions. For information on how to delete a partition, see Deleting Partitions.
Automatic partitioning assigns library resources proportionately among the partitions, grouping tape drives according to their interface type. The three supported tape drive interface types are Fibre Channel, SCSI, or Serial Attached SCSI (SAS).
The maximum number of partitions that you can create is equal to the number of drives in the library. On the Automatically Create Partitions screen, you can select the number of partitions to create, from a minimum of one to a maximum that equals the number of tape drives in your library. The default is the number of available tape drive interface types (interface types of drives that are not currently assigned to a partition).
Automatic partitioning does not allow you to mix FC, SCSI, and SAS tape drive interfaces within the same partition. For example, if your library contains a combination of FC and SCSI tape drives, you must select at least two partitions on the Automatically Create Partitions screen. The library then automatically groups the FC tape drives and SCSI tape drives and assigns them to different partitions. If you choose to create fewer partitions than you have available interface types, then some tape drive interface types will not be assigned to any partition. Create the partitions manually if you want different tape drive types within the same partition. To manually create partitions, use the Web client. See Manually Creating Partitions.
When the library automatically creates partitions, the first SCSI or SAS tape drive assigned to a partition is designated as the control path tape drive by default. If the partition contains only Fibre Channel (FC) tape drives, a control path tape drive is automatically selected only if I/O blades are not installed in the library. If I/O blades are installed in the library, you must manually select a control path for partitions that contain FC tape drives directly connected to host applications. Do not select a drive control path for partitions that are connected to an I/O blade. For more information about drive control paths, see About Control Paths.
Before automatically creating partitions, verify that all tape drives are unloaded and that all cartridges are in their appropriate storage slots. For information on unloading tape drives, see Unloading Tape Drives.

NOTE: This operation should not be performed concurrently by multiple administrative users logged in from different locations. You can access the appropriate screens, but you cannot apply changes while another administrative user is performing the same operation. |
Users with administrative privileges can create partitions, but users with user privileges cannot.
If one or more partitions are currently configured, the Setup - Partitions screen appears. If no partitions are configured, the Setup - Partition Creation Mode screen appears.

NOTE: By default, the library applies the ADIC Scalar i500 library emulation type and Standard barcode format to each partition. You can change these settings by modifying the partition after it has been created. For information on modifying partitions, see Modifying Partitions. |
