The PVSREN utility routine can generate autonomous pubsets from the disk copies of an SM or SF pubset (pubset copy) within a system.
PVSREN uses the local replication functions of the disk storage systems to create autonomous pubsets by renaming pubset copies. In the case of SM pubsets the rules for renaming the volume sets are stored in a parameter file in which the new catalog ID for is defined for each volume set using the SET-NAME-OF-NEW-VOLUME-SET statement.
The CREATE-PUBSET-FROM-MIRROR statement is used to create an autonomous pubset. Here the MIRRORING-METHOD operand determines whether or with which function PVSREN generates a copy:
The specification MIRRORING-METHOD=*SPLIT-MIRROR requires that the pubset’s copies have already been split and are available in double-point notation (see "Double-point notation for mirror disks"). In this case PVSREN only renames an autonomous pubset.
PVSREN uses MIRRORING-METHOD=*CLONE(...)/*SNAP(...) to generate a copy on the basis of clone units or snap units and renames this as an autonomous pubset.
