Target Specification
powerman
target hostnames may be specified as comma separated or space separated hostnames or
host ranges. Host ranges are of the general form: prefix[n-m,l-k,...], where n < m and l < k, etc., This form
should not be confused with regular expression character classes (also denoted by ''[]''). For example,
foo[19] does not represent foo1 or foo9, but rather represents a degenerate range: foo19.
This range syntax is meant only as a convenience on clusters with a prefix NN naming convention and
specification of ranges should not be considered necessary—the list foo1,foo9 could be specified as
such, or by the range foo[1,9].
Some examples of powerman targets follows.
Power on hosts bar,baz,foo01,foo02,...,foo05:
powerman --on bar baz foo[01-05]
Power on hosts bar,foo7,foo9,foo10:
powerman --on bar,foo[7,9-10]
Power on foo0,foo4,foo5:
powerman --on foo[0,4-5]
As a reminder to the reader, some shells will interpret brackets ([ and ]) for pattern matching.
Depending on your shell, you might need to enclose ranged lists within quotes. For example, in tcsh, the
last example above should be executed as:
powerman --on "foo[0,4-5]"
15.9.2 The
pmpower
tool
The
pmpower
utility is a high level tool for manipulating remote preconfigured power devices connected
to the
console server
either via a serial or network connection. The PDU UPS and IPMI power devices are
variously controlled using the open source
PowerMan, IPMItool
or
Network UPS Tools
and Black Box’s
pmpower
utility arches over these tools so the devices can be controlled through one command line:
pmpower [-?h] [-l device | -r host] [-o outlet] [-u username] [-p password] action
-?/-h
This help message.
-l
The serial port to use.
-o
The outlet on the power target to apply to
-r
The remote host address for the power target
-u
Override the configured username
-p
Override the configured password
on
This
action
switches the specified device or outlet(s) on
off
This
action
switches the specified device or outlet(s) off
cycle
This
action
switches the specified device or outlet(s) off and on again
status
This
action
retrieves the current status of the device or outlet
Examples:
To turn outlet 4 of the power device connected to serial port 2 on:
# pmpower -l port02 -o 4 on
To turn an IPMI device off located at IP address 192.168.1.100 (where username is 'root' and
password is 'calvin':
# pmpower -r 192.168.1.100 -u root -p calvin off
