• The use_on_next_boot field of the last cell containing core I/O cannot be modified
to
n.
• If modifying the CLM value of a cell in any partition other than the local parti-
tion, it is preferable to use the -u
option.
-P Partition Name Specifies the name of the partition. The characters which can appear in a valid par-
tition name are
a-z, A
-Z, 0-9, - (dash), _ (underscore), " " (space) and
. (period).
If the partition name includes a space then the name should be enclosed in double
quotes. The partition name can have a maximum of 64 characters; it should not
start with a dash (
-).
-r cell Specifies the core cell choices. A core cell choice is a configured cell which has
attached core I/O. If the core cell of a partition is deleted then the firmware will
select the first core cell choice as the next core cell. One to four core cell choices can
be specified. The first cell specified is the first core cell choice, the second cell
specified is the second core cell choice, the third cell specified is the third core cell
choice and the fourth cell specified is the fourth core cell choice. Use of this option
will override previous core cell choices. So, if the order of a given cell is changing,
all of the core cell choices should be specified in the new order.
A cell can be specified either in the local (cabinet# /slot#) or global (cell# )format.
For example, the cell located in cabinet 0, slot 1 is identified in the local format as
0/1 or in the global format as 1.
-s path Specifies the secondary boot path. path specifies a physical hardware path. Note:
On Itanium-based platforms, only boot paths of the local partition can be modified.
-T flag Specifies that whether Hyper-Threading should be enabled or not (only if cell sup-
port this feature). If this option is not specified, Hyper-Threading property will not
be changed. The valid values for flag are:
y enables Hyper-Threading, which allows multiple threads to run concurrently
on each CPU.
n disables Hyper-Threading.
-t path Specifies the alternate boot path. path specifies a physical hardware path. Note:
On Itanium-based platforms, only boot paths of the local partition can be modified.
-u username[:] Specifies the required authorization to access a partition other than the local system
(but can also be used as a loopback access to the local partition).
The
-h option is required if this option is used.
If this option is specified, the command prompts for the password.
username specifies a configured user name on the target partition.
Note: This command is a Web-Based Enterprise Management (WBEM) Client
Application. The
-u option accesses the target partition using a Secure Sockets
Layer (SSL) connection. If errors are reported, check that the conditions described
in the DEPENDENCIES section are satisfied.
Mapping of Global Cell Numbers to Local Cell Numbers
The cabinets in a complex are numbered starting from 0. The cell slots in each cabinet are also numbered
starting from 0. Each cabinet can have a maximum of 8 cells. For example, the cells located in cabinet 0
will have the following cell numbers in global format: 0, 1, 2, 3, 4, 5, 6, 7. The cell numbers in
corresponding local format will be 0/0, 0/1, 0/2, 0/3, 0/4, 0/5, 0/6, 0/7.
Similarly the cells located in cabinet 1 will have the following cell numbers in global format: 8, 9, 10, 11,
12, 13, 14, 15. The cell numbers in corresponding local format will be 1/0, 1/1, 1/2, 1/3, 1/4, 1/5, 1/6, 1/7.
From the above convention the cell located in cabinet 1, slot 0 is identified in the local format as 1/0 or in
the global format as 8. The
parstatus command will display the above cell as "cab1,cell0". The cell
located in cabinet 1, slot 4 is identified in the local format as 1/4 or in the global format as 12. The par-
status command will display the above cell as "cab1,cell4".
RETURN VALUE
The
parmodify command exits with one of the following values:
