If, after capacity has been decreased, the total number of cells allocated to all
partitions is still less than the new licensed capacity, you do not need to
reconfigure the partitions.
Host Notification of Capacity Changes
When storage capacity is added or removed, the library controller notifies all affected
hosts according to their interface requirements. SCSI hosts are notified by a “Mode
Parameters Changed” unit attention. The host must re-audit the library to determine
the specific configuration changes. See the appropriate tape management software
documentation for detailed procedures and commands.
