Managing the AMASS File System
•Both source and destination media must be of the same type and have the same block size and capacity.
Tip
Manufacturing variations make “equal” tapes have variable lengths. Consequently, AMASS does not check tape lengths before allowing you to do the volcopy process.
The system administrator must make sure the source and destination tapes are the same types.
However, AMASS will check MO and WORM lengths.
Requirements are illustrated by the following figure:
Read Drive
Source Media
•Media is known to File System Database.
•Block size and capacity is same as destination volume.
•Inlet and outlet the volumes with either the volinlet and voloutlet commands or the bulkinlet and bulkoutlet commands, depending on the library connection.
•To prevent changes to the source volume, it is marked
Write Drive
Destination Media
•Media is unknown to File System
•Block size and capacity is same as source volume.
•Load and unload the volumes with the mediamove utility.
•During process, destination volume is flagged as IU (Inactive, Unformatted) and assigned to SP (space pool) volume group when displayed with the sysperf, sysop, and vollist commands.
