You can create a TC pair using volumes that have been assigned the access attribute by the Data Retention Utility (DRU). However, you cannot specify a volume with the "S-VOL Disable" attribute as a TC S-VOL.
The following table shows whether a DRU volume with the specified access attribute can be used as a TC P-VOL or S-VOL.
