Table III.h. Task: -a mem:::base:range
[:base|floating]
Explanation Specifies an explicit address space of memory
starting at base bytes and extending for
range megabytes. If the target vPar is in the
live monitor database, both quantities are
rounded upward as required to be aligned on a granule
boundary.
Values base: An unsigned 64-bit integer <=
(0x1000000000000000 - appropriate granularity)
range: A positive 64-bit integer <=
(0x100000000000 - granularity)
Usage The target vPar can be Up or Down.
Restrictions
No part of the range may be already owned by this
or another vPar.
If the vPar is in the live monitor database, the entire
range (after rounding upward if necessary) must
exist in the system.
The entire range must exist within one memory type.
CLM ranges can span cells. For base and range
calculations, use the granularity in effect for
the memory type of the address range.
If the target vPar is Down, the total memory
allocated in specific ranges must not exceed
the vPar’s memory size specification for
memory of that type.
If the vPar is not in the live monitor database, base
must lie on either a CLM or ILM granule boundary, or
the command fails.
Usage If the target vPar is Down, addition of specific
Guidelines memory ranges does not increase
the total amount of memory allocated to the vPar.
Any such memory is a part of that total amount.
Caution: It is possible to specify memory ranges
and sizes such that none of the virtual partitions
will launch. Hewlett-Packard recommends that
users configure specific memory ranges only when
required for performance reasons. In other
situations, specify only total memory and allow
the monitor to manage
