LIBRARY PARTITIONS

physicallibraries—onelibraryperconfiguredpartition.Partitioning
simplifiesstorageconsolidationthroughthecreationofvirtuallibraries,
eachwithitsowndrivesandmedia.Eachpartition:
 Hasexclusiveaccesstothetapedrivesandmediastorageassignedtoit.
 Cancontroltheroboticstomovemediawithinthepartition.
Thelibrarysupportstwotypesofpartitions,storagepartitionsand
cleaningpartitions.IfanystoragepartitionsuseaFibreChanneldriveto
