FASTREPLICATION: Indicating a recovery preference

Explanation: FASTREPLICATION is an optional parameter that indicates whether the use of fast replication for data set recovery is required, preferred, or not desired.

The following are parameters of the FASTREPLICATION parameter:
PREFERRED
Indicates that fast replication should be used when possible. If fast replication cannot be used, the data set is recovered through traditional copy methods.
REQUIRED
Indicates that if fast replication cannot be used, the recovery is to fail.
NONE
Indicates that only traditional copy methods are to be used.

Defaults: None.

Notes:
  1. Using the FASTREPLICATION parameter overrides the FASTREPLICATION value specified using the SETSYS FASTREPLICATION command. If not specified, the value of SETSYS FASTREPLICATION is used.
  2. FASTREPLICATION is valid only for recovery from disk. If the recovery is from tape, the parameter is ignored.
  3. FASTREPLICATION is valid with DSNAME only. It is not valid with the COPYPOOL or TOVOLUME parameters.
  4. To recover data sets only when fast replication can be used, specify FROMDASD with FASTREPLICATION(REQUIRED).
