7.1.3 Examples
To grant shutdown and reboot privileges to user 'jsmith' (note that ALL can be replaced with
localhost or the hostname of the HP Insight CMU management node):
jsmith ALL = NOPASSWD: /opt/cmu/tools/halt.exp /opt/cmu/tools/reboot.exp
The /etc/sudoers file supports creating "command aliases" when you need to refer to a group
of commands. For example, the following lines configure useful HP Insight CMU aliases by grouping
the commands into three categories: power control, provisioning, and the rest of the features:
Cmnd_Alias CMU_POWER = /opt/cmu/tools/halt.exp /opt/cmu/bin/cmu_power /opt/cmu/tools/boot.exp
/opt/cmu/tools/reboot.exp
Cmnd_Alias CMU_IMAGE = /opt/cmu/bin/cmu_backup /opt/cmu/bin/cmu_clone /opt/cmu/tools/cmu_autoinstall_node
Cmnd_Alias CMU_ETC = /opt/cmu/bin/cmu_console /opt/cmu/tools/cmu_cn_install /opt/cmu/bin/cmu_firmware_mgmt
Now you can grant power control to user 'cjones' as long as he provides a password:
cjones ALL = CMU_POWER
To let user 'bstevens' control power and provisioning without a password:
bstevens ALL = NOPASSWD: CMU_POWER CMU_IMAGE
To grant user 'sbarney' full HP Insight CMU control without a password (similar to the current root
user capability in the HP Insight CMU GUI):
sbarney ALL = NOPASSWD: CMU_POWER CMU_IMAGE CMU_ETC
If a non-root user in the HP Insight CMU GUI tries to execute a command without sudo privileges,
the sudo command prevents it from running and logs the incident.
7.2 HP Insight CMU diskless API
As of version 7.1, HP Insight CMU supports a diskless API. This diskless API provides hooks into
the creation, management, and booting of diskless logical groups in HP Insight CMU. This diskless
API enables the development and/or integration of different "diskless OS" implementations within
HP Insight CMU.
