This partitioning has been expanded with the new library firmware and half-high drive integration. Now it is possible to configure 1, 2, 3 or 4 partitions in the 4U library. Additionally the 2U library can now be configured into one or two partitions. Each library must contain at least one drive per logical library (partition). In a partitioned library, the Operator Control Panel (OCP) only reports the status of logical library 1 in the main menu due to space limitations. You must navigate to the logical libraries status in the OCP to get the information on the additional library partitions. Partitioning of 2U Libraries When two half height drives are installed in a 2U library, the library firmware will support partitioning in the same way that the 4U supports partitioning with two full height drives today. The first partition will contain the first magazine and the first drive. The second partition will contain the second magazine and the second drive. The I/O station (if configured as I/O) will be shared, as is done with the partitioned 4U library. One full height drive is "Drive 1". When using half height drives, the first half height drive position will be called "Drive 1", The second half height drive position will be called "Drive 2." Partitioning of 4U Libraries When one or more half height drives are added to a 4U library, the drive naming will change. Currently, the first full height drive is "Drive 1" and the second full height drive is "Drive 2". When you consider that each full height drive slot may contain one or two half height drives, there are four potential drives in the space Appendix A.
