Tivoli Storage Manager Deduplication Sample Architecture 4.4.2 Device class creation backups The random disk storage pool uses the built-in disk device class. Device classes must be created for the sequential file deduplication pool, and the tape storage pools. • sequential file > define devclass largefile devt=file mountlimit=750 maxcap=102400M dir=/tsmfile1,/tsmfile2,/tsmfile3,/tsmfile4,/tsmfile5,/tsmfile6,/tsmfile7,/tsmfi le8 • tape > define library TS3500 libtype=scsi shared=yes autolabel=overwrite > define path scorpio2 TS3310 SRCTYPE=server DESTTYPE=library device=/dev/smc0 online=yes > define drive TS3500 drivea element=autodetect serial=autodetect … Repeat the define drive for other drives … > define drive TS3500 drivej element=autodetect serial=autodetect > define path scorpio2 drivea SRCTYPE=server DESTTYPE=drive LIBRARY=TS3500 device=/dev/rmt0 … Repeat the define path for other drives … > define path scorpio2 drivej SRCTYPE=server DESTTYPE=drive LIBRARY=TS3500 device=/dev/rmt9 > define devclass TS3500devc devtype=LTO library=TS3500 4.4.3 Storage pool creation Below are the commands used to create the four storage pools used in this sample architecture. The options controlling reclamation, migration, and duplicate identification are set to disable the automatic launching of these tasks. Instead, the tasks are scheduled to run at specified times as detailed in a later section. • tape > define stgpool tapepool ts3500devc maxscratch=30 reclaim=100 collocate=group reusedelay=3 reclaimprocess=3 • random disk > update stgpool BACKUPPOOL nextstgpool=tapepool migprocess=5 highmig=100 lowmig=0 > update stgpool ARCHIVEPOOL nextstgpool=tapepool migprocess=5 highmig=100 lowmig=0 > define volume ARCHIVEPOOL /tsmdisk/arch01.dsm format=512000M > define volume BACKUPPOOL /tsmdisk/back01.dsm format=512000M > define volume BACKUPPOOL /tsmdisk/back02.dsm format=512000M Document: Tivoli Storage Manager Deduplication Sample Architecture Date: 09/28/2012 Version: 1.0 Page 18 of 21

Archive objects are retained for 1000 days. > define domain GOLD > define policy GOLD GOLD > define mgmtclass GOLD GOLD GOLD > assign defmgmt GOLD GOLD GOLD > define copygroup GOLD GOLD GOLD type=backup destination=FILEPOOL VERE=nolimit VERD=10 RETE=60 RETO=NOLIMIT > define copygroup GOLD GOLD GOLD type=archive destination=FILEPOOL RETV=1000 > activate pol GOLD GOLD • The silver domain provides up to 40 days of backup retention and uses the random disk to tape storage pool hierarchy.
