Since command line options are processed left-to-right, you can modify resources in a
static partition by specifying -S dynamic on the command line before any resource
options, then specifying -S static after all resource options to prevent further resource
modifications.
-b kernel_path Specifies the absolute path to a bootable kernel for the partition. If the option is omit-
ted, the kernel_path is not changed. The kernel path may be changed while vp_name
is running.
-o boot_opts Specifies the command-line string, except for the kernel path, applied when the virtual
partition is booted. For example, if a non-partitioned system start string at the ISL
prompt is:
ISL> hpux -iS /stand/vmunix
the boot_opts string is the -iS portion of this string. Note that if the string includes a
space, the string must be quoted.
Refer to "Monitor and Shell Commands" in Installing and Managing HP-UX Virtual
Partitions for a full list of supported boot option strings.
The boot options may be changed while vp_name is running. If the
-o option is omit-
ted, boot_opts is not changed.
-P new_vp_name Specifies a new name for the virtual partition being modified, that is, after all
modifications are successfully applied to vp_name , it is renamed to new_vp_name ,
assuming no virtual partition with that name already exists in the monitor database,
the specified alternate database file, or the default database file /stand/vpdb.
The name can consist of alpha-numeric characters
A-Z, a-z, 0-9, the underbar charac-
ter (
_), and period (.). The maximum length of the name is 239 characters.
The vPar name may be changed while vp_name is running. If the
-P option is omitted,
vp_name is not changed.
-a rsrc -a adds resources to a virtual partition.
-d rsrc -d deletes resources from a virtual partition.
-m rsrc -m modifies existing resources in a virtual partition.
rsrc is a hardware resource specification, as described in detail in the vparresources(5)
manpage. You should refer to the section "CPUs and Instant CAPacity (iCAP)" in that
manpage when adding CPU resources.
The iCAP product will not allow CPU activation in excess of that shown by iCAP’s
Intended Active number. The underlying nPartition is said to be compliant.
vpar-
modify fails if you attempt to add one or more processors such that the total proces-
sors assigned to all vPars would exceed Intended Active . Refer to the Instant CAPacity
(iCAP) User’s Guide available at
http://docs.hp.com
, and to the icod(5) manpage
for more information.
A summary of resource syntax forms is shown in Table 1. Multiple resource
specifications in the same command are allowed, but some syntax forms are restricted
to specific options, and some are only allowed once. Both are indicated in Table 1. In
any case, resources in multiple specifications must not repeat or conflict with each
other.
