VOL Control Statement
This statement defines the volume to be modified.
VOL Statement Syntax
The VOL control statement uses the fixed format shown below. Start the VOL
command in position one.
VOLnxxxxxx,ownerid
VOL
n
xxxxxx
Ownerid
Specifies which DASD volume is to be modified.
Indicates the relative position (1—6) of a volume label within a group of
volume labels, normally a 1.
Identifies the volume to be modified. We recommend using all six characters.
(For more information, see the IBM Initialize Disk Utility Manual.)
Optional operand. Specifies the code that identifies the owner to be entered
into the volume label. 1—14 alphanumeric characters; embedded blanks
acceptable.
Example
// JOB CAINTDK
// ASSGN SYS001,1E8 /* DASD VOLUME TO BE MODIFIED */
// EXEC CAINTDK

Converting EXTENTs—DYNCONV
The DYNCONV program lets you convert the EXTENT statements in a job
stream to accommodate the value of the CA Dynam/D trigger. It produces a
listing of the old and new EXTENT statements.
This program also accepts an optional statement, the CONVERT control
statement, as the first input statement to DYNCONV. The CONVERT command
lets you convert the number of allocated tracks/blocks to a new value based
upon new and old device types or a user-defined conversion ratio.
If you want to modify only the relative track/block value to the CA Dynam/D
trigger value, omit the CONVERT control statement. However, if you supply a
CONVERT statement for a job stream whose EXTENTs already specify the CA
Dynam/D trigger, the allocation value conversion is still performed.
