Connect the SCSI or SAS Cables and the SCSI Terminator
UsethefollowingstepstoconnecttheSASorSCSIcablesandtheSCSI
terminator.
1. Shutdownthehostcomputer(s).
Note: Ifyouarefollowingtheseinstructionstoreplaceadriveina
librarythatisalreadyinstalled,alsoshutdownandpoweroff
thelibrary(seePowerOfftheLibraryonpage136).
2. Connectcablestothedrives,asappropriateforyourdesired
configuration.SeeDriveInterfacePortsonpage32forthelocationof
theports.
Note: ForSASdrives,thetwoSASportscannotbeusedsimultaneously
toprovideredundantdatapathsbetweenthehostsandthe
drive.However,theycanbeusedtoprovidefailovercapability
intheev entthatcommunicationtotheportcurrentlyinuseis
interrupted(seeDriveConnectivityFailoveronpage37).
3. ForSCSIdrives,connecttheprovidedUltra3WideActiveSCSI
terminatortotheunusedSCSIconnectoronthedrive.
Note: Ifyoudaisy‐chainedtwoLTO‐3drivesinthelibrary,connectthe
terminatortotheunusedSCSIconnectoronthelastdriveinthe
chain.
4. Connecttheotherendofthecable.
 SCSI—ConnecttheotherendoftheSCSIcabletotheLVDSCSI
HBAinthehostcomputer.
 SAS—ConnecttheotherendoftheSAScabletoastandard
6Gb/secondSAS(HBA)inthehostcomputerortoaSASexpander.
5. RepeatStep1throughStep4foranyadditionaldrivesinthelibrary.
