You only have to initialize a CKDS the first time you start ICSF on a system. When you initialize a CKDS, you can copy the disk copy of the CKDS to create other CKDSs for use on the system. You can also use a CKDS from another ICSF system.
At any time, you can read a different disk copy into storage. For information about how to read a disk copy into storage, see Local CKDS refresh.
