Installation guide

For example, to modify the dump-sp-threshold attribute for the
generic subsystem, issue a command like the following:
# /sbin/sysconfig -r generic dump-sp-threshold=20480
To modify the value of more than one attribute at a time, include a list on
the /sbin/sysconfig command line. For example, to modify the
dump-sp-threshold attribute and the locktimeout attribute, issue a
command like the following:
# /sbin/sysconfig -r generic dump-sp-threshold=20480
locktimeout=20
You do not include a comma between the two attribute specifications.
5.3.7 Managing Subsystems and Attributes Remotely
You can use the /sbin/sysconfig h command to administer
configurable subsystems and dynamic subsystem attributes remotely on a
local area network (LAN). This ability allows you to administer several
systems from a single machine.
Each system you want to administer remotely must have an
/etc/cfgmgr.auth file that contains the full domain name of the local
system. The name in the /etc/cfgmgr.auth file should be identical to the
name in either the /etc/hosts file or in the Berkeley Internet Domain
(BIND) or Network Information Service (NIS) hosts databases, if you are
using BIND or NIS. You must create the /etc/cfgmgr.auth file; it is not
on your system by default. The following shows an example cfgmgr.auth
file:
salmon.zk3.dec.com
trout.zk3.dec.com
bluefish.zk3.dec.com
To manage subsystems and attributes on remote systems, you include the
h flag and a hostname with the /sbin/sysconfig command. For
example, to load the decnet subsystem on a remote host named MYSYS,
you issue the following command:
# /sbin/sysconfig -h MYSYS -c decnet
In the previous example, a decnet.mod file must exist in either the
/subsys directory or the /var/subsys directory on the remote system
before the subsystem can be loaded. If the loadable subsystem subset is
kitted correctly, the
subsystem-name.
mod file is installed on the remote
system when you use the setld command to install the loadable
subsystem.
