Table III.o. Task: -d cell:cell_id :cpu::num
Explanation Deletes num CLPs on cell cell_id from the
vPar’s configuration.
Values cell_id: A positive integer or 0
num: A positive integer
Usage If the target vPar is in an alternate
Restrictions database file:
o Total number of CPUs >= min
o num CPUs from cell_id must
currently be assigned to the vPar.
In addition, if the target vPar is in the
live monitor database:
o cell_id must exist in the configuration.
o num CPUs from cell_id must
currently be assigned to the vPar.
Table III.p. Task: -d cpu:path
Explanation Releases the path binding of a CPU at the
specified hardware path, or deletes the CPU
from the vPar.
Value A text string of the form returned by the
ioscan command, such as "0/13"
Usage If the vPar is Down, the CPU must have been
Restrictions previously assigned by path to the
vPar using the -a cpu:path option.
If the vPar is Up:
o A CPU must exist at path,
o It cannot be the boot processor,
o Deleting the CPU cannot lower the total
CPU count below min.
Usage If the vPar is Down, the deletion does not
Guidelines reduce the number of total CPUs assigned to
the vPar. Instead, the CPU becomes a non-CLP,
meaning any CPU can be assigned by the monitor
when the vPar next boots.
If the vPar is Up, the CPU is deleted from the
vPar, unless it is the boot processor, or the
deletion would reduce total CPU count below
min. The CPU need not have been
user-assigned by path.
Hewlett-Packard recommends that users configure
specific CPUs only when required for performance
reasons. In other situations, specify only the
total number of CPUs (num) and allow the
monitor to manage the actual CPU allocation.
