HP-UX Reference (11i v2 07/12) - 1M System Administration Commands N-Z (vol 4)

p
parmodify(1M) parmodify(1M)
-B Specifies to reboot the partition now. The default is not to boot. If this option is
specified and the partition to be modified is not the local partition, then the command
proceeds only if the specified partition is not active. Also this option is useful only if
the -a option or the -d option or a clm_value has been specified.
-r cell Specifies the core cell choices. A core cell choice is a configured cell which has
attached core IO. 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 pre-
vious 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.
-I IPaddress Specifies the IP address that should be used by management tools such as
parmgr to
address the target partition. This value must be consistent with the IP address that is
assigned to the partition once HP-UX is installed and networking is configured.
-b path Specifies the primary boot path. path specifies a physical hardware path. Note: On
Itanium-based platforms, only boot paths of the local partition can be modified.
-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.
-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 support
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.
-P Partition Name Specifies the name of the partition. The characters which can appear in a valid parti-
tion name are a-z, A-Z, 0-9, - (dash),
_ (underscore), " " (space) and . (period). If
the partition name includes space then the name should be enclosed within double
quotes. The partition name can have a maximum of 64 characters.
-k s_lock:p_lock Specifies the lock keys provided by parmgr for the Stable Complex Configuration
Data and Partition Configuration Data. The lock keys should always be specified in
pairs. If either lock key is not available -1 should be specified as a placeholder. For
example: if the s_lock is available but the p_lock is not available, then it should be
specified as -k s_lock:-1.
Note: The -k option is intended for use by system management tools which invoke
the parmodify command programmatically. Command line users should avoid this
option.
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 correspond-
ing 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". See parstatus(1).
