Managing Systems and Workgroups: A Guide for HP-UX System Administrators

Conﬁguring a System

Reconﬁguring the Kernel (HP-UX 11i Version 2)

Chapter 3 323

With a -P (Parse) option, the commands produce an output format

designed to be parsed by scripts or applications. This format is described

in “Parsing Command Output” on page 363. Scripts and applications

must parse this output format, because HP supports release-to-release

compatibility of output format only when the -P option is used.

The kernel conﬁguration commands all use a common format for error,

warning, note, and progress messages. It is the same format used by the

Software Distributor package, and therefore already familiar to most

administrators.

ERROR: This is an error message. It explains why the requested

operation cannot complete.

WARNING: This is a warning message. The requested operation

completed, but not smoothly. A situation may exist that

needs correction.

NOTE: This is a note. It provides information about how the

operation completed, or other information of potential

interest to the administrator.

* This is a progress message. It displays the steps

completed during the operation.

Common Exit Status Codes

All of the kernel conﬁguration commands exit with one of the status

codes in Table 3-13.

Common Security Constraints

Any user can run the kernel conﬁguration commands to query

conﬁguration information. However, access to conﬁguration information

is subject to standard Unix ﬁle system permissions on the relevant ﬁles.

Superuser privileges are required to make any conﬁguration changes.

Table 3-13 Exit Status Codes

0 Operation was successful.

1 The requested changes could not be applied to the currently

running system. They are being held and will be applied at next

boot.

2 The operation could not complete successfully.
