To create a system group, use the group_create command, for example:

spacecmd {SSM:0}> group_create group3 "Example system group 3"

To list system groups, use the group_list command, for example:

spacecmd {SSM:0}> group_list
group1
group2
group3

To add client systems to a system group, use the group_addsystems command.

spacecmd {SSM:0}> group_addsystems group3 svr1.mydom.com

You can also specify systems by the software channels to which they are subscribed or the results of a system search, for example:

spacecmd {SSM:0}> group_addsystems group3 channel:ol6-x86_64
spacecmd {SSM:0}> group_addsystems group3 ip:192.168.1

See Section 8.3, “Searching for Systems Using spacecmd”.

To display the details of a system group, use the group_details command.

spacecmd {SSM:0}> group_details group3
Name               group3
Description:       Example system group 3
Number of Systems: 1

To create a union of two or more system groups, create an empty group and specify the groups to the group_addsystems command.

spacecmd {SSM:0}> group_create group4 "Example system group 4"
spacecmd {SSM:0}> group_addsystems group4 group:group1 group:group2

To create an intersection of two or more system groups, clear the contents of the system set in the System Set Manager, use the ssm_intersect command to create the intersection as the new system set, create an empty group and specify the system set as ssm to the group_addsystems command.

spacecmd {SSM:0}> ssm_clear
spacecmd {SSM:0}> ssm_intersect group:group1 group:group2
spacecmd {SSM:2}> group_create group5 "Example system group 5"
spacecmd {SSM:2}> group_addsystems group5 ssm
spacecmd {SSM:2}> ssm_clear
spacecmd {SSM:0}>

To remove client systems from a system group, use the group_removesystems command.

spacecmd {SSM:0}> group_removesystems group3 svr1.mydom.com
Systems

Remove these systems [y/N]: y

To delete a system group, use the group_delete command.

spacecmd {SSM:0}> group_delete group3
