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.
Source Media
Destination Media

Database—it does not have a volume
numbe
r.
•
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.
• 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

marked Read-Only after the volcopy process
begins. The exception is the Backup Volume.
AMASS recognizes the Backup Volume and
leaves its’ status as read-write.
