CPFMTXA
sext
is the starting cylinder or page that is to be allocated. It is a 1-digit to 5-digit
decimal integer (1-digit to 9-digit decimal integer for fixed-block devices) and
must be within the size of the real device where vdev is located. If the starting
cylinder or page is all you specify, only that cylinder or page is allocated.
-eext
-END
is the last of the range of cylinders or pages whose allocation is specified. It is
a 1-digit to 5-digit decimal integer (1-digit to 9-digit decimal integer for
fixed-block devices). If specified, it must be equal to or greater than sext. It
must be within the size of the real device described by this virtual device.
Specify END to allocate all cylinders or pages as the specified type.
An alternative to using a dash (–) to separate sext from eext or END is one or
more blanks. For example, you may enter CPFMTXA 191 MYDISK 0 20 instead
of CPFMTXA 191 MYDISK 0-20
If you do not specify eext or END, only sext is allocated.
.num
.END
is a 1-digit to 5-digit decimal integer (1-digit to 9-digit decimal integer for
fixed-block devices) designating the number of cylinders or pages being
allocated. If specified, num must not be zero, and the sum of sext and num
must not exceed the size of the real DASD upon which the specified virtual
device is located. Specify END to allocate all cylinders or pages as the
specified type. If you do not specify num or END, one cylinder or page is the
default.
Interactions With ICKDSF
The following shows the prompts that are issued if ICKDSF is available, and you
enter CPFMTXA only. In this example, the information entered by the user is in
italics. This example uses a non fixed-block device. Using a fixed-block device
would result in similar prompts with page replacing cylinder.
