Conﬁguring and enabling PRM on the command line

Conﬁguring PRM

Chapter 7 125

Step 4. Load the conﬁguration using one of the following commands:

To initialize, moving user processes to the owners’ initial groups and

moving applications to their assigned groups, use the command:

# prmconfig -i [-f configfile] {-s | -c}

To keep the existing assignments of users, processes, and groups, use the

command:

# prmconfig -k [-f configfile] {-s | -c}

Use the -f configfile option to specify a ﬁle other than the default

/etc/prmconf. The -s option displays warnings regarding the

conﬁguration ﬁle. (The -c option displays a subset of the -s warnings.)

Step 5. Enable PRM’s disk bandwidth manager if it is not already enabled:

# prmconfig -e DISK

Alternatively, enable all PRM resource managers using prmconfig -e

without any additional arguments:

# prmconfig -e

Removing disk bandwidth shares

To remove a disk bandwidth record manually:

Step 1. Open the conﬁguration ﬁle in a text editor.

Step 2. Remove the line corresponding to the disk bandwidth record you wish to

remove. Disk bandwidth records have the following form:

VOLUME:{ PRMID | GROUP }:SHARES::

Step 3. Repeat Step 2 until all disk bandwidth records referencing VOLUME are

removed if you no longer want VOLUME under PRM control.

Step 4. Ensure there is still a one-to-one correspondence between disk

bandwidth records and group/CPU records if there are any disk

bandwidth records still present in the conﬁguration.

Step 5. Save the ﬁle and exit the text editor.
