ADDING OR REPLACING A DRIVE
Prepare the Library and the Host Computer
Beforeaddingorreplacingadrive,makesureyouaddressthe
requirementsinthefollowingsections.
Discontinue Backups
Ifyouarereplacingorremovinganexistingdrive,discontinuebackupor
restoreoperationsasrequired.
Fibre Channel or SAS drives Backupsrunningtootherdrivesinthelibrary
(orpartition)cansafelycontinuewhileyoureplaceadrive,aslongasthat
driveisnottheoneexportingthelibrary(thatis,providingtherobotic
controlpathforthepartition).Ifthemalfunctioningdriveistheexporting
driveforthepartition,stopbackuporrestoreoperationstothepartition.
SCSI drives Ifyouplantopower‐offthehostbeforeinstallingorreplacing
aSCSIdrive,stopbackuporrestoreoperationstoallofthedrives
connectedtothehost.Ifyouchoosenottopower‐offthehost,the
requirementtostopbackuporrestoreoperationsdependsonhowthe
driveisconnectedandconfiguredinthelibrary.
 Exportingdrive—Ifthedrivethatyouarereplacingistheexporting
driveforthepartition,stopbackuporrestoreoperationstoallofthe
drivesinthepartitionbeforeremovingthedrive.
 LTO‐3orLTO‐4driveisnotdaisy‐chained—Ifthedriveisnotthe
exportingdriveandisnotdaisy‐chainedwithanotherdrive,operations
totheotherdrivescancontinue.
 Twodrivesdaisy‐chained(LTO‐3only)—IftwoSCSIdrivesaredaisy‐
chainedonthesameSCSIbus,removingadriveinthechaininterrupts
communicationsonthebus.Beforeremovingadrive,stopbackupor
restoreoperationstobothofthedrivesinthedaisychain.
Power-Off the SCSI Host
SpectraLogicrecommendsthatyoushutdownandpower‐offthehost
beforeinstallingorreplacingaSCSIdrive;thisisnotrequiredforFibre
ChannelorSASdrives.
Important
Only use tape drives obtained from Spectra Logic in the library. When replacing a
drive that is assigned to a partition, the new drive must be the same technology
and generation as the one you replace.
Caution
Improperly adding or removing a device from a SCSI bus can cause the host
computer to crash. If you leave the host running during this procedure, Spectra
Logic assumes no responsibility for damage to data or equipment.
