HP-UX Secure Resource Partitions (SRP) A.02.01 Administrator's Guide

12 Starting and Stopping SRP Compartments

This chapter describes how to start and stop SRP compartments. For complete syntax information, see

srp(1M).

This chapter addresses the following topics:

• 12.1 SRP Startup and Shutdown Processing

• 12.2 Starting an SRP Compartment

• 12.3 Stopping an SRP Compartment

12.1 SRP Startup and Shutdown Processing

By default, all SRP compartments are automatically started at system startup time and are

automatically stopped at system shutdown time. Each SRP home directory contains an sbin

subdirectory (/var/hpsrp/compartment_name/sbin) that contains a subtree similar to the

system /sbin subtree. Each sbin directory contains an init.d directory and an rcN.d

subdirectory tree with the subdirectories rc0.d, rc1.d, rc2.d, rc3.d, and rc4.d.

The SRP product also includes the /opt/hpsrp/bin/util/srp_rc script. This is a sequencer

script that is executed at system startup and shutdown time and is similar to the /sbin/rc utility, (see

rc(1M)), with the following differences:

• The /opt/hpsrp/bin/util/srp_rc script first restarts itself in the target compartment by

executing the following command:

privrun -c compartment_name /opt/hpsrp/bin/util/srp_rc

This causes all the processes and scripts executed by srp_rc to run in the target SRP

compartment.

• The srp_rc script executes the files in the

/var/hpsrp/compartment_name/sbin/init.d/rcN.d directories (instead of the files

in the /sbin/init.d/rcN.d directories).

The /opt/hpsrp/bin/util/srp_rc script executes the scripts in the rcN.d directories in

alphabetical order. When the system starts up, SRP traverses these directories in ascending

order and executes scripts in these directories. When the system shuts down, SRP traverses

these directories in descending order and executes scripts in these directories.

NOTE: The numeric portion of the subdirectory name does not correspond to the system run

level at which the scripts are executed. The system run level at which the scripts are executed

is determined by the run level at which the SRP master script, /sbin/init.d/srp, runs (run

level 3 when the system starts up and at run level 2 when the system shuts down).

At system startup or shutdown time, the SRP scripts are executed as follows:

• The /sbin/init.d/srp file is linked to the following files:

/sbin/rc3.d/S999srp

/sbin/rc2.d/K001srp
