Use DEFINE STORAGE to change the storage size of your virtual machine.
size
is the size of the extent you are defining (when CONFIGuration is not
specified). size is of the form nu, where n is a decimal number and u is the unit
of measure (see Table 7 on page 186).
CONFIGuration
allows you to define multiple, non-contiguous storage extents. You can also
define a single extent just as you would without CONFIGuration, for example:
DEF STOR 64M
DEF STOR CONFIG 0.64M
-decrement
1 Up to seven additional extents can be specified.
.size
DEFINE STORAGE
The advantage of CONFIGuration is that it provides more detail in the
command response and in the output of the QUERY VIRTUAL STORAGE
command.
0.size
is the size of the first extent you are defining (when CONFIGuration is specified)
which always starts at address 0. size is of the form nu, where n is a decimal
number and u is the unit of measure (see Table 7 on page 186).
address
is the starting address of the extent you are defining. address is of the form nu,
where n is a decimal number and u is the unit of measure (see Table 7 on page
186). The first address must be zero. Subsequent extent start specifications
must specify a higher address than the ending address of the last extent plus
one (contiguous extents are not valid).
