Thecomponentidentifierforeachdriveisbasedonitslocationrelativeto
theframeandtheDBAwhereitisinstalled,asviewedfromthebackofthe
library(seeFigure29onpage64).Thecomponentidentifierforadriveis
shownasFRx/DBAx/fTYPE-DRVx,where:
 FRx isthenumberoftheframefromlefttorightwhenviewedfromthe
frontofthelibrary.
 DBAxisthenumberoftheDBAcontainingthedrive.
 fTYPEistheinterface(fforFibreChannel)anddrivetype(LTOforan
LTOdriveorTS11x0foraTS11x0technologydrive).
 DRVxisthenumberofthedrivebayintheDBA,asviewedfromthe
backofthelibrary.
Forexample,Figure30showsthecomponentidentifierforaFibreChannel

fLTO‐DRV1)ontheDrivesscreen.TheDrive Typedescriptorindicatesthat
thedriveisanIBMLTO‐5FibreChanneldrive.
FIBRE CHANNEL CONNECTIVITY
Thelibrary’sroboticsandthelibrary’sdrivesconnecttothehostsystem
overaFibreChannelarbitratedlooporfabric.TheseFibreChannel
connectionscarrytwotypesofinformation:
 Thecommandsfromthestoragemanagementsoftwarethatcontrolthe
roboticmotionandtheread/writeoperationsofthedrives.
 Thedatabeingtransferredtoandfromadrivebythehost.
ThefollowingsectionsdescribetheFibreChannelconnectivityforthe
library’sroboticsandthedrives.
