If you do not specify this
attribute when you create a
vPar, the default memory
allocated is 2 MB. For more
information, see Table 35 (page

mem::mem_size[:{b|f}]
The memory is specified in
megabytes. The minimum
amount of memory you allocate
to a vPar must be the total of the
following:
• The amount of memory
required by the operating
environment in the vPar.
• The amount of memory
required by the applications
running on the vPar.
Memory
If you do not specify this
attribute when you create a
vPar, the vPar will not have
access to network and storage
devices.
-a rsrcYou can allocate virtual network
switches and virtual storage
devices to the vPar. The VSP
presents devices as virtual
devices to the vPar.
The vPar network consists of
vNICs and vswitches. For vPars
to communicate either with other
vPars or outside the VSP system,
each virtual network of the vPar
must be associated with a
vswitch. If you start a vPar
without a vswitch, the vPar has
no network communication
channel.
vPar also supports DIO
networking where physical
devices are directly presented.
DIO devices do not require a
vswitch.
Virtual storage devices are
backed by physical devices on
the VSP system. You can specify
one of the following devices –
disk, dvd, tape, changer,
burner, or hba. For more
information about virtual
devices, see Section 9.1.6
(page 136).
