16.2.1 Defining library, drives, and associated paths on the server As we said, the library must be shared between server and Storage Agents for LAN-free operations. Therefore, in contrast to a typical library definition, you must enable the library for SAN sharing using the shared=yes parameter; otherwise, the library clients will not be able to communicate with the drives. Additionally, Tivoli Storage Manager V5.3 and later supports an option when defining the library, resetdrives. This is mainly used in cluster failover configurations, since its purpose is to reset SCSI reservations on defined drives during the server instance startup. However, it can also be helpful in non-clustered solutions, so we set the resetdrives value to yes, as in Example 16-3. Example 16-3 Library and drive definition tsm: ATLANTIC>define library 3582_shared libtype=scsi shared=yes resetdrives=yes autolabel=yes serial=autodetect ANR8400I Library 3582_SHARED defined. tsm: ATLANTIC>define path atlantic 3582_SHARED srctype=server \ cont> desttype=library autodetect=yes device=/dev/smc0 ANR1720I A path from ATLANTIC to 3582_SHARED has been defined. tsm: ATLANTIC>define drive 3582_shared dr00 serial=autodetect \ cont> element=autodetect cleanfrequency=none ANR8404I Drive DR00 defined in library 3582_SHARED. tsm: ATLANTIC>define drive 3582_shared dr01 serial=autodetect \ cont> element=autodetect cleanfrequency=none ANR8404I Drive DR01 defined in library 3582_SHARED. tsm: ATLANTIC>define path atlantic dr00 srctype=server desttype=drive \ cont> library=3582_shared device=/dev/rmt0 online=yes ANR1720I A path from ATLANTIC to 3582_SHARED DR00 has been defined. tsm: ATLANTIC>define path atlantic dr01 srctype=server desttype=drive library=3582_shared \ cont> device=/dev/rmt1 online=yes ANR1720I A path from ATLANTIC to 3582_SHARED DR01 has been defined. Tip: LTO drives have an internal self-cleaning mechanism, which cleans a drive any time a tape is to be loaded. Therefore, you do not need to set the cleaning frequency in the drive definition. 530 IBM Tivoli Storage Manager Implementation Guide
