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