KeysthataresplitintosharescanonlybeimportedfromUSBdevices;they

Forexample,ifyouselectthe2‐of‐3optionandexportedthekeytoUSB

Use a Key Stored in the Library
Iftheencryptionkeyusedtoencryptthedataiscurrentlystoredinthe
library,usethefollowingstepstodecryptandrestoredata.
Note: Ifthedatawasnotencryptedusingthekeycurrentlystoredin
thelibrary,thelibrarypromptsyouwiththemonikerofthekey
thatisrequiredtodecryptthedata.Youmustimportthekeyas

page318beforethedatacanberestored.
1. IfyouselectedSecureInitialization,accesstheencryptionfeature(see
LogIntotheEncryptionFeatureonpage284).
2. Ifnecessary,importthecartridgescontainingthedatatobedecrypted
intothelibrary(seeImportingCartridgesonpage198).
3. Ifthepartitioncontainingthecartridgesdoesnotcurrentlyhavethe
