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
on another
ICSF system if the system has the same master key value.
Note: Use of a CKDS on another system depends both upon where the CKDS
was initialized and the cryptographic hardware type of the other system.
At any time, you can read a different disk copy into storage. For
information about how to read a disk copy into storage
on a single
system, see Performing a Local CKDS Refresh. For information about
how to read a disk copy into storage when in a sysplex environment,
see Performing a coordinated refresh. For a description of how to use the Master Key Entry panels to
enter the master key, see Steps for entering the first master key part. For a
description of how to use the TKE workstation to enter
the master key, refer to z/OS Cryptographic Services ICSF TKE Workstation User's Guide.
