Privilege Class: A
Use CPRELEASE to release a disk that was previously accessed using the
CPACCESS command or the CP_ACCESS statement.
For more information on the CPACCESS command, see page “CPACCESS” on
page 79. For more information on the CP_ACCESS statement, see the z/VM: CP
Planning and Administration book.
fm is the file mode letter of the minidisk that you want CP to release.
ASYNChronous
tells CP to schedule the command and lets you enter other commands before
the CPRELEASE command completes. When the command is complete, CP
displays the following:
CPRELEASE request for disk filemode completed
ASYNCHRONOUS is the default.
SYNChronous
tells CP to process the command immediately and does not allow you to enter
any other commands until the CPRELEASE command completes. CP must wait
until all the files are closed before it can release a minidisk. If there are a large
number of open files and you specify the SYNCHRONOUS option, you may be
forced to wait for some time before you can enter any other commands.
1. When you enter a CPRELEASE command, CP removes from storage all the
files on the minidisk that were cached into storage as a result of CPCACHE
commands or a CPCACHE FILES file.
