RELEASE RELEASE Use the RELEASE command to free an accessed disk ana make the files on
it unavailable. The format of the RELEASE command is: r ----------_._------_._-_._-----, , RELease , { CUU} (DET()]] , mode , L _____ _
cuu is the virtual device address of the disk that is to be released.
mode Valid addresses are 001 through 5FF for a
basic control mode and 001 through FFF for a extended control mode. virtual machine in
virtual machine in
is the mode letter at which the disk is currently accessed.
DET specifies that the disk is to be detached from your virtual
machine configuration; CMS calls the CP command DETACH.
1. If a disk is accessed at more than one mode letter r the RELEASE cuu
command releases all modes. If you access a aisk specifying the
mode letter of an active disk r the first disk is released.
2. YOl cannot release the system disk (S-disk). 3. When a disk is releasedr the user file directory is freed from storage and that storage becomes available for other CKS commands and programs. When you release a read/write CKS disk r either with the RELEASE command or implicitly with the FORMAT command, the user
file directory is sorted and rewritten on disk; user(s) who may
subsequently access the same disk may have a resultant favorable
decrease in file search time.
4. When a disk is released, any read-only extensions it may have are
not released. The extensions may be referred to by their own mode
letters. If a disk is then accessed with the same mode as the
original parent disk, the original read-only extensions remain extensions to the new disk at that mode.
5. In CMS/DOS, when you release a disk, any system or programmer unit assignments made for the disk are unassigned. DASD cuu DETACHED
This is a CP message that is issued when you use the DET option.
It indicates that the disk has been detached.
