Important: If you plan to use one of the PostScan features that uses a Global
Spare, one or more Global Spare drives must be configured for the partition.

Decideontheexportingcontroller(LTO‐5orlatergenerationtapedrive,RIM,
orF‐QIP)forthelibrary’srobotics.
Notes:
 Ifyouplantoselectbothportsontheexportingcontroller,makesurethatthe
softwareusedwiththepartitionsupportsusingmultiplecontrolpathsand
thattheportsarecabledcorrectly.Selectingbothportsprovidesredundancy,
butrequiressoftwarethatsupportstwocontrolpathstotherobotics.
 Youcanselectmultiplesimilar(RIMsandF‐QIPs,ordrives)exporting
controllers,andexportthesamechangerinterfaceoverthemtoprovide
redundancy,aslongasyourstoragemanagementsoftwarecansupportthis.
Thesemultiplepathscannotbeusedatthesametime.
 Themaximumnumberofexporterssupportedbythelibraryissix.
 Sixdriveexporterscanbeusedforsixdifferentpartitions,ormultiple
exporterscanbeconfiguredinthesamepartition,reducingthemaximum
numberofpartitions.
 AsingleRIMcanexportuptoeightpartitions,butstillonlycountasone
exporter;asingleRIM2canexportupto16
