Useful openstack commands
This section includes some commands that you might find useful.
Adding a user to access the IBM Power Virtualization Center graphical user interface instead of root
The following commands enable a user to access the IBM Power Virtualization Center (IBM PowerVC) graphical user interface (GUI). You most likely want to change the password to something much more secure.
# adduser IBM PowerVC -p SECRET
# source /opt/ibm/IBM PowerVC/IBM PowerVCrc
# export OS_USERNAME=root
# export OS_PASSWORD=SECRET
# openstack role add --project ibm-default --user IBM PowerVC admin
Adding and listing a project
To create a project and list it, run the following commands:
# openstack project create --description "Six Project" six

+----------------------------------+-------------+
Creating users and roles for access to a project
You can create users and add roles to them in Version 1.3.1 by running the following commands. You might want to use a more secure password.
# adduser sixadmin -p SECRET
# adduser halfdozen -p SECRET
#
# openstack role add --project six --user sixadmin admin
# openstack role add --project six --user halfdozen admin
# openstack user list
+--------------------------+-------------------+
| ID | Name |
+--------------------------+-------------------+
. . .
| 1dd45dfca1d83b0e38 . . . | IBM PowerVC |
| 79d13683f8ab37b1d5 . . . | sixadmin |
| 897db369914c6109c4 . . . | halfdozen |
+--------------------------+-------------------+
Changing a role
Perhaps you need to change a role after you discover that a user is not an administrator. To do so, run the following commands:
# openstack role remove --project six --user halfdozen admin
# openstack role add --project six --user halfdozen deployer
Useful IBM PowerVC-config commands
This section is a quick reference to several commands.
The following command finds the current settings with example output from IBM PowerVC V1.3.1.1 on RHEL7.1 BE on POWER8. Most of the settings are the default values except the network ones. Adding -h after the command shows you how to set the same variable.
The following command can be used to set the network domain as follows as the root user:
# /usr/bin/IBM PowerVC-config compute server-domain --set ats.uk.ibm.com
The default domain name was updated for the specified hosts. Verify that no tasks are in-progress, then run the '/opt/ibm/IBM PowerVC/bin/IBM PowerVC-services nova restart' command to restart the nova services and complete the operation.
General subcommands
Here are general IBM PowerVC-config subcommands.
Listing an interface configuration
To list an interface configuration, run the following command:
# IBM PowerVC-config general ifconfig
IBM PowerVC IP version : 4
IBM PowerVC management address: vm17.ats.uk.ibm.com
IBM PowerVC hostname: vm17
ifconfig Change the hostname or IP address of the IBM PowerVC controller
Listing an IP address
To list an IP address, run the following command:
# IBM PowerVC-config general ipaddress
Current value: 9.137.62.17
ipaddress The IP address of the IBM PowerVC controller Warning: This option will be deprecated in future releases.
Listing a host name
To list a host name, run the following command:
# IBM PowerVC-config general hostname
Current value: vm17
hostname The hostname of the IBM PowerVC controller Warning: This option will be deprecated in future releases.
Identify subcommands
The following commands are identify subcommands for the IBM PowerVC-config command.
Listing a token expiration
To list a token expiration, run the following command:
# IBM PowerVC-config identity token_expiration
Current value: 6:00:00
Default value: 6:00:00
token_expiration Configure the expiration interval for the identity token
The output is in Hours:Minutes:Seconds format.

Useful scripts
The scripts that are provided in this section format output as report quality output.
Listing the defined projects and user assignments
To list the projects and users that are defined, use the openstack role assignment list command. A script is helpful to align the output into something more readable.
 
Note:
•The -f option stops TTY style output.
•The -c column-name option selects what is output.
•The --name option removes the hexadecimal D and provides the names (note the double "-").
•Removing the @Service lines removes internal users.
By project, role, and user name
A simple script produces list quality output from the openstack command:
# openstack role assignment list -c Project -c Role -c User --names -f value
| grep -v @Service | sed 's/@Default//g' |
awk '{ printf "%-15s %-15s %-15s ", $3, $1, $2 }' | sort
